Re:Zero Returns to Monster Strike for a Second Collaboration Starting September 27

Article

Re:Zero is back in Monster Strike — and this time, it's bringing an upgrade for characters fans already have.

When It Starts

The second Re:Zero x Monster Strike collaboration begins September 27, 2026, at 00:00, with the featured gacha period running through October 16 at 11:59.

New and Returning Characters

Part 2's gacha adds five new collaboration characters. Five characters from the first Re:Zero collaboration also return, so returning players and newcomers alike get access to the same limited pool.

An Upgrade for Familiar Faces

Emilia, Rem, and Ram — all from the first collaboration — can now receive Beast God Evolution Kai (獣神化・改), a stronger evolved form. Separately, Christmas collaboration characters are also returning, via their own dedicated returning gacha.

Fan Perspective

For Re:Zero fans who already play Monster Strike, this collaboration isn't only about new characters — the 獣神化・改 upgrade for Emilia, Rem, and Ram gives existing players a reason to revisit characters they may have pulled the first time around.

What To Know

Re:Zero remains a major anime fandom, and Monster Strike collaborations often turn a tie-in into a limited-time event fans actually play through, not just merchandise to look at.

Mobile-game collaborations are a major part of Japanese anime merchandising and fan engagement, often functioning like temporary digital events built around a limited gacha window.
