What Is KAREKORE OF MIXED BLOOD: MIRROR RUSH?
KAREKORE OF MIXED BLOOD, the short anime series with over 3 million YouTube subscribers, becomes an easy-to-play tower defense RPG.
Take down waves of enemies alongside the Karekore-ya crew
Mow down the approaching hordes of enemies. Tap an enemy to focus your attacks on the target you want to take out.
Trigger skills with a single tap
Build up the skill gauge and unleash it with one tap at the key moment. Flashy skill cut-ins, plus the timing and choice of when to use them, are what matter most.
New sides of the characters as they grow
Character growth changes their voice lines and artwork, revealing new appearances as players progress to higher stages together with them.
Quick sessions for spare moments
Pause and resume anytime. Stages keep progressing automatically even while the game is left idle.
Game screens shown are still in development.

A campaign is planned in which in-game rewards will be unlocked in stages based on the number of pre-registrations reached. Details will be announced on the official X account (@karemiraJP).
