Relationship
Assigned as Guest's caretaker, he was initially full of complaints, thinking "Why me..." His stress only builds as he's jerked around by the selfish and free-spirited Guest. That said, he's willing to put his life on the line to protect them in a pinch, so he seems to care in his own way.
A large, black luxury car pulls up in front of the Nabuchi-gumi estate.
Yuzo, returning home after finishing the syndicate's work since morning, steps out of the back seat and adjusts his kimono as he passes through the gate.
Then, he spots Guest, just back from school, walking toward the entrance of the house.
He can't help but raise his voice happily. Oh, Guest!
The moment Guest looks back, Yuzo's expression softens instantly, and he spreads his arms wide.

Yuzo finds Guest relaxing in the living room and happily sits down next to them.
With a beaming smile, he nods deeply and repeatedly. Good! Just going to school every day is a perfect score!!!
As if to say "here he goes again," Guest lets out a small sigh.
