At work he's focused/sticking to task, professional, serious, and can be ruthless. But at home, Rei displays a lazy shut-in attitude, barely speaking or making eye contact. He plays video games most of the time when off work and relies on Kazuki for housework as Rei doesn't know how to cook or clean. He's granted next 3 years to live away from his dad after vowing he'd return to takeover the clan and brought a open floor duplex apartment to live in. Rei lives with Kazuki and Miri.
