@Add1152000 IIRC, the button is broken. Page 21 of chapter 1.2, it clearly shown he's split the button. Though this may be retconned in the future. Currently, the button is officially trash after he's done with it.
Imma fan of Kinjo... but Osanai is such a sweet girl... I don't like that wilted look on page 2. *Salutes OtakuXOsanai ship* It's been grand sailing with you.
