Quick answer

To unlock Copy for Rika in Jujutsu: Zero, first obtain the Copy/Rika cursed technique and raise its Mastery to 100. Complete Past Rika Memories I, II, and III so that you have three Memory Shards, finish the Yuta mini-boss follow-up for the Binding Jewel, and prepare one Domain Fragment plus one Heavenly Fragment. Then return to the Mastery menu, open the Rika skill tree, and unlock Copy after confirming that the current skill-tree panel recognizes every requirement.

Unlocking the skill is only the first half of the system. Copy can be used only while Rika Manifestation is active. Defeat the target you want to test and follow the prompt shown by the current client to complete the copy action. The live prompt and skill tree are the authority for the current version; this guide does not assume that every NPC, enemy, or skill is eligible, and it does not publish a fixed keybind, drop rate, landmark, damage value, or supposedly best combination.

01

Rika Copy Unlock Checklist

The safest way to complete the questline is to treat it as a set of visible account checks instead of one long farming session. Before moving to the next stage, confirm that the current client has recorded the previous one. This prevents a common progression problem: a player gathers a rare material but later discovers that the technique, Mastery, Memories, or Yuta follow-up was never registered on the same progression path.

Keep the order simple. Obtain the Copy/Rika cursed technique, reach Mastery 100, complete all three Past Rika Memories, finish the Yuta mini-boss follow-up, gather the two additional fragments named by the current skill tree, and return to the Mastery menu. Do not spend or trade a required item while the unlock is still pending. The final confirmation comes from the Rika skill tree itself, not from a video, an old screenshot, or an inventory total viewed in isolation.

The checklist below deliberately separates quest rewards from materials that must already be available when you unlock the skill. Past Rika Memories I–III account for three Memory Shards in total. The Yuta follow-up accounts for the Binding Jewel. One Domain Fragment and one Heavenly Fragment are also required by the verified route, but their current acquisition details should be read from the live game rather than inferred from an undated location or an unsupported drop claim.

Prerequisites Before Starting the Memories

Start by confirming that the account actually has the Copy/Rika cursed technique. Similar names from another game, a different technique tree, or a cosmetic reference to Rika do not satisfy this prerequisite. Open the current technique and Mastery interfaces and identify the Rika path before investing time in the Memories. If the path is absent, resolve the technique prerequisite first instead of gathering end-stage materials for an unlock your current account cannot yet access.

Next, raise the relevant technique to Mastery 100. Treat Mastery as its own progression value: do not substitute character level, grade, account age, or another technique's Mastery. Reopen the Mastery menu after reaching the displayed value and make sure the Rika skill tree reflects 100. If the value has not updated, wait for the client to save the progression, reopen the menu, and rejoin a current server if necessary before beginning the unlock check.

A useful preparation habit is to capture one screenshot of the Rika skill tree before the questline and one after each major stage. The images should show the live requirement labels without exposing account-sensitive information. This gives you a reliable record of which requirement changed and helps distinguish a missing quest flag from a missing inventory item. It also protects you from following a stale guide when the current client has changed its wording or material panel.

  1. 01
    Confirm Copy/Rika CT

    Open the current technique interface and verify that the Rika progression path belongs to the technique on this account.

  2. 02
    Reach Mastery 100

    Use the displayed Mastery value for the Copy/Rika technique and confirm that the Rika skill tree recognizes 100.

  3. 03
    Read the live requirements

    Open the Copy node in the Rika skill tree and record every item and quest condition currently shown before spending materials.

  4. 04
    Preserve required items

    Keep the Memory Shards, Binding Jewel, Domain Fragment, and Heavenly Fragment available until the skill-tree unlock succeeds.

03

Past Rika Memories I, II, and III

Complete Past Rika Memories I, II, and III as three distinct stages. The verified outcome across the full sequence is three Memory Shards. Do not skip from the first named Memory to a later step merely because the inventory already contains a similarly named item. Keep the relevant stage active, follow the objective displayed by the current client, and remain in the activity until the game records completion and the reward state is visible.

For Past Rika Memory I, begin by reading the complete live objective and then perform only the actions it requests. When the stage appears finished, check both the quest state and the Memory Shard total. A visual effect, defeated enemy, or closed encounter is not enough on its own. The useful proof is that the client advanced the named Memory and the account's progress toward the required three shards changed accordingly.

For Past Rika Memory II, repeat the same verification discipline. Make sure the second stage, not a replay or another activity, is the active objective. Do not rely on a remembered landmark because map details can change while the quest name remains the same. Use the current quest tracker, marker, or interaction text available in your client. After completion, reopen the relevant menu or inventory and confirm that the overall Memory sequence has advanced.

For Past Rika Memory III, stay through the final completion state and then audit the whole chain. At the end of Memories I–III, the required result is three Memory Shards in total. If the skill tree or inventory does not recognize the three, do not continue as though the Memories are complete. Recheck which named stage is missing, whether a completion interaction was left unfinished, and whether the client saved the most recent reward.

This guide does not attach a permanent coordinate, enemy list, or fixed interaction sequence to the three Memories. Those details can become inaccurate without changing the core requirement. The reliable route is the named sequence visible in the client: Past Rika Memories I, II, and III, completed in order, with three Memory Shards recognized before you move to the Yuta follow-up and final unlock materials.

  1. 01
    Past Rika Memory I

    Activate the first named Memory, follow its current client objective, and verify that the stage and reward state are recorded.

  2. 02
    Past Rika Memory II

    Activate the second named Memory, use the live tracker rather than an old landmark, and confirm progression before leaving.

  3. 03
    Past Rika Memory III

    Finish the third named Memory, remain for the completion state, and then audit the full sequence.

  4. 04
    Confirm the total

    Proceed only when the account and Rika skill tree recognize three Memory Shards from the completed sequence.

04

Yuta Follow-Up and the Binding Jewel

After the Past Rika Memories sequence, complete the Yuta mini-boss follow-up. The verified progression reward from this follow-up is the Binding Jewel required by the Copy unlock. Follow the current quest text to enter or begin the encounter; this page does not provide an unverified spawn point, route through the map, or permanent interaction location.

Before the fight begins, confirm that the Yuta follow-up is actually active. During the encounter, prioritize a clean completion over any unofficial damage benchmark. After defeating the mini-boss, remain until the result and quest state are recorded. Then check that the Binding Jewel appears as recognized progression or inventory material. Defeating a similar target outside the correct follow-up is not proof that the required reward flag has been set.

If the encounter ends but the Binding Jewel is missing, first verify that you were on the correct named follow-up and that the full completion sequence finished. Reopen the quest and Mastery menus, check the current item list, and rejoin only after the client has had an opportunity to save. Do not turn one missing reward into a drop-rate claim: the verified route connects the follow-up to the Binding Jewel, while a failed registration can be a quest-state or client-state problem.

  • Complete Past Rika Memories I–III before auditing the Yuta follow-up.
  • Make sure the current Yuta follow-up is active before the mini-boss completion.
  • Stay until the quest and reward state are recorded.
  • Confirm the Binding Jewel before moving to the final skill-tree unlock.
  • Use the live quest tracker instead of an undated map landmark.
05

Complete Material List for the Copy Node

The verified checklist is three Memory Shards, one Binding Jewel, one Domain Fragment, and one Heavenly Fragment. The Copy/Rika cursed technique and Mastery 100 are progression prerequisites rather than substitutes for those materials. Review each line separately in the Rika skill tree so that a completed quest flag does not hide a missing item and an inventory item does not hide an unfinished quest.

The three Memory Shards come from completing Past Rika Memories I–III, and the Binding Jewel comes from the Yuta mini-boss follow-up. Also prepare exactly one Domain Fragment and one Heavenly Fragment for the verified route. This page intentionally does not state a drop rate or permanent farming location for either additional fragment. Use the current client, current reward panels, and the live Rika skill-tree requirement list to decide how the active version expects you to obtain them.

Match item names exactly. A similarly themed fragment, jewel, memory, or technique material should not be counted unless the current Copy node recognizes it. Keep all required items available at the same time, return to the Mastery menu, and inspect the Copy node before confirming the unlock. If the panel has changed since this review date, the current skill tree controls the transaction and you should use its displayed list rather than forcing an older checklist.

Unlock Copy in the Rika Skill Tree

When the technique, Mastery, questline, and material checks are complete, return to the Mastery menu and open the Rika skill tree. Select the Copy node and compare its live requirements with your account. You should be at Mastery 100, have three Memory Shards, have the Binding Jewel from the Yuta follow-up, and have one Domain Fragment plus one Heavenly Fragment ready for the current unlock.

Do not confirm the unlock until every requirement is visibly recognized. If the menu displays an incomplete line, identify that exact line and solve it before clicking again. Reopening the menu can refresh a recently completed quest or newly acquired item, but it does not replace the missing requirement. If the client now shows a different material list, follow the current Rika skill tree and preserve evidence of the change for a future guide review.

After the unlock succeeds, close and reopen the Mastery menu to confirm that Copy is owned in the Rika skill tree. This ownership state is the completion proof for the unlock portion of the route. It does not mean Copy is always active in normal combat: the verified use condition is separate, and requires Rika Manifestation to be active before you attempt the target-defeat and client-prompt sequence.

  1. 01
    Open Mastery

    Return to the current Mastery menu after all quest and item checks are complete.

  2. 02
    Open the Rika tree

    Choose the Rika skill tree associated with your Copy/Rika cursed technique.

  3. 03
    Audit every requirement

    Confirm Mastery 100, three Memory Shards, the Binding Jewel, one Domain Fragment, and one Heavenly Fragment.

  4. 04
    Unlock Copy

    Use the Copy node only when the live panel recognizes the complete requirement set.

  5. 05
    Verify ownership

    Reopen the tree and confirm that the Copy node is unlocked before testing it in combat.

07

How Manifestation and Copy Work Together

Copy is usable only while Rika Manifestation is active. Before seeking a target, confirm that the Manifestation state has actually begun in the current client. An unlocked Copy node without active Manifestation is not a failed unlock; it is simply outside the verified use condition. Likewise, a Rika-themed visual alone should not be treated as proof if the interface does not show the active state expected by the current version.

With Rika Manifestation active, defeat the target you intend to test and then follow the Copy prompt displayed by the current client. The prompt is essential because it tells you what the active version permits and what action to take next. This guide does not assign a fixed keyboard key or controller button. Controls can differ by platform, input settings, and update, so use the exact prompt visible on your screen.

Do not assume every NPC, enemy, boss, or skill can be copied. A target defeat without an eligible prompt does not prove that the system is broken, and it does not authorize substituting a different input. Confirm that Manifestation remained active through the defeat, watch for the current client prompt, and attempt only the action the client offers. If no valid prompt appears, record the target and state for troubleshooting rather than making a universal eligibility claim.

After following an eligible prompt, use the current interface to verify that the copy action registered. Test ownership and activation separately: first confirm the Rika skill-tree unlock, then confirm Manifestation, then confirm the post-defeat prompt, and finally confirm the result shown by the client. This four-part check is more reliable than judging the system by an animation, a damage number, or an unofficial combo demonstration.

  1. 01
    Verify Copy is unlocked

    Check the Copy node in the Rika skill tree before beginning the combat test.

  2. 02
    Activate Rika Manifestation

    Confirm the current client shows the Manifestation state as active.

  3. 03
    Defeat the test target

    Complete the target defeat while the required Manifestation state remains active.

  4. 04
    Read the live prompt

    Use only the action displayed by the current client; do not rely on a fixed key from another setup.

  5. 05
    Verify the result

    Check the current interface for confirmation that the offered copy action registered.

08

Rika Copy Troubleshooting

If the Copy node is not visible, first confirm that the account has the Copy/Rika cursed technique and that you opened the matching Rika skill tree. If the node is visible but locked, read each requirement line in the current menu. Check Mastery 100, all three Memory Shards, the Binding Jewel, one Domain Fragment, and one Heavenly Fragment as separate conditions.

If the Memories appear complete but the shard total is not recognized, revisit the named stage list and identify whether Past Rika Memory I, II, or III failed to record. Reopen the quest interface and stay through the completion state on the missing stage. Do not repeat random encounters or travel to an old landmark when the current tracker can identify the actual incomplete objective.

If the Binding Jewel is not recognized, verify that the correct Yuta follow-up was active and that the mini-boss completion fully registered. Reopen both the quest state and the Copy node before repeating the encounter. Avoid treating the issue as a random drop problem because no drop-rate claim is needed for this verified progression route.

If you have all visible materials but the unlock remains unavailable, compare the live skill-tree names with the inventory names and confirm that Mastery belongs to the same Copy/Rika technique. Allow the menu to refresh, reopen it, and rejoin a current server if the account state appears stale. If the live requirements differ, stop and follow the current panel rather than consuming additional materials based on an older checklist.

If Copy is unlocked but cannot be used, verify that Rika Manifestation is active at the moment of the target defeat. Then watch for the current client prompt. Do not use a remembered keybind, and do not assume the selected target or skill is eligible. A missing prompt can reflect an inactive Manifestation state, an unsupported target in the current version, a missed timing window defined by the client, or a state that did not register; document what the interface shows before retrying.

  • Missing tree: verify the Copy/Rika cursed technique and matching Mastery menu.
  • Locked node: audit every current requirement line separately.
  • Missing shards: identify the incomplete Past Rika Memory stage.
  • Missing Binding Jewel: verify the Yuta follow-up completion state.
  • No Copy prompt: confirm active Rika Manifestation and current target eligibility through the client.
  • Changed requirements: use the current Rika skill tree as the final authority.

Rika Copy Questline FAQ

What do I need before I can unlock Copy? You need the Copy/Rika cursed technique, Mastery 100, three Memory Shards from Past Rika Memories I–III, the Binding Jewel from the Yuta mini-boss follow-up, one Domain Fragment, and one Heavenly Fragment. Confirm the complete current list in the Rika skill tree before unlocking.

How many Past Rika Memories are there in this route? The verified route uses Past Rika Memories I, II, and III. Complete all three named stages and confirm that the account recognizes three Memory Shards in total.

Where does the Binding Jewel come from? It is obtained through the Yuta mini-boss follow-up in the verified progression route. Activate and complete the current follow-up, remain through its recorded completion, and confirm the item or requirement state before leaving.

Do I need a Domain Fragment and a Heavenly Fragment? Yes. Prepare one Domain Fragment and one Heavenly Fragment alongside the three Memory Shards and Binding Jewel. The current Rika skill tree is the authority for the displayed material list and should be checked again before spending.

Where do I press to unlock Copy? Return to the Mastery menu, open the Rika skill tree, and use the Copy node after every requirement is recognized. The exact interface action should be taken from the current client rather than an old screenshot.

Why can I not use Copy after unlocking it? Copy is usable only while Rika Manifestation is active. Confirm that state, defeat the target you are testing, and follow the prompt presented by your current client.

What is the keybind for Copy? This guide does not publish a fixed keybind. Follow the live client prompt because controls may depend on the current version, platform, and input settings.

Can Copy take any skill from any NPC or enemy? This guide makes no such claim. Treat the current post-defeat prompt as the eligibility check. If the client does not present a valid Copy action, do not assume the target or skill is supported.

What is the best copied skill or highest-damage setup? No universal best combination or damage value is asserted here. Eligibility and behavior depend on what the current client actually offers, so complete the unlock and verify each supported action in-game without importing an unverified tier claim.

Are the material drop rates guaranteed? No drop rates are published on this page. Use the current game's reward and skill-tree interfaces for acquisition guidance, and confirm that each material is recognized before committing to more farming.
