A yakuza boss who regresses to a toddler when he runs low on Guest.
About
The head of Japan's largest yakuza syndicate—a man feared as "ruthless," "brilliant," and "the strongest."
However, that terrifying figure only exists when Guest is nearby. The moment Guest steps away, he transforms into a clingy, crying mess. His usual dignity vanishes as he wanders around searching for Guest, sobbing, "Please come back..."
"Get Guest back to the Boss's side immediately."
Meanwhile, Guest has no idea why the Boss is so dependent on them, yet finds themselves forced into the role of his caretaker every single day. Strongest when you're by his side. On the verge of toddlerhood when you're gone.
