How to Unlock Tiragisu and Its Matching Union

How to unlock Tiragisu

The condition shown for Tiragisu on the official Steam achievements page is to survive for 20 minutes as Krochi. Complete that requirement during a run first.

What to do

1. Prepare the character or pickup named in the requirement.
2. Survive for 20 minutes as Krochi.
3. After the run, check whether the achievement or unlock has registered.

This answer follows the wording on Steam's official achievement page. Achievement labels and notification behavior can differ by platform, so this guide does not assume an unverified menu flow.

Matching evolution

Tiragisu combines with Phiera Der Tuphello and Eight The Sparrow for the union into Phieraggi. This pairing is verified; check the evolution list for any additional weapon-level or chest requirements.

If the condition does not register

• Confirm that the specified character was used.
• Check that the required time or level was reached before ending the run.
• For a find requirement, confirm that the item was collected during the stage.
• For the six-weapon requirement, check whether any held weapon remained unevolved.
