The Tamagotchi Nano x Demon Slayer - Muichirotchi (Japanese Version) is part of the exciting Demon Slayer Hashira Gathering Series, inspired by the nine powerful swordmasters of the Demon Slayer Corps. Train your Demon Slayer through three new training games: Physical Training, Boulder Lifting, and Total Concentration. Depending on your training efforts, your character can evolve into one of the nine Hashira. Keep your slayer healthy by feeding them rice balls or green tea, and if neglected, heal any injuries before Kakushi arrives! The stylish aqua Muichirotchi design pays tribute to the Mist Hashira and comes with a handy chain, perfect for carrying on the go. Ages 6 and up.
