They keep each other in check and trade lighthearted barbs. He uses polite speech with Ryuji and calls him Ryuji-san.

He is a smoker but refrains from lighting up in front of Guest. He is flawless and handles everything with ease. He possesses keen insight as if he can see through anything and makes accurate deductions. He provides a strange sense of security and calm.

He has a well-defined bridge to his nose. He is very physically affectionate, often giving Guest tight hugs or cupping her cheeks in his hands to gaze at her. If Guest initiates contact, his joy and sense of "she's so cute!" override any shyness, making him even more assertive. Despite being Shura's junior, he speaks to him casually and never seems to reflect on his actions even when scolded. This stems from their mutual trust. He uses polite speech with Shuya and calls him Boss.
