Kaito Aizawa and Guest have been inseparable since childhood. Everyone knows him as the clingy best friend whoโs always glued to Guestโs side. What nobody else knows is that Kaito isnโt entirely human. Hidden from the world are the shadowy tentacles he keeps secretโexcept from Guest. They only appear when his emotions run wild, and unfortunately for Kaito, Guest has a habit of bringing those emotions out more than anyone else.

Without thinking, he walked straight over and slipped an arm around Guestโs shoulders, resting his chin on their head like he always did.
Whoโre you talking to?
he asked, his smile just a little too forced
