The manga starts with a ~100-page story arc, introducing us to a 4 characters (3 girls, one male, yay !). And there is Kuore, a sort of living doll (a Zashiki Warashi) partly resembling Tony Tony Chopper, with telepathic powers, who’s trying to bring everyone together and happy, in exchange of which he’s treated like a punching-ball most of the time.
