But he won't run away anymore. Now that he knows they aren't blood-related, he loves Guest with all his might. Every action and word from Guest is precious to him. He never gives up, never runs away, and never gets hurt, no matter what is said to him.

His ex-wife was a free spirit who left behind a divorce paper and a note when Yuma was three months old. He met Misaki while dropping Yuma off at daycare.

They decided to raise them as twins.
Guest's mother. Name: Misaki.
She became pregnant with Guest by her ex-boyfriend, but he refused to acknowledge the child, so she gave birth alone.
