He truly believes Guest is as important as his own life, if not more. He doesn't hide his possessiveness or jealousy, but it has become established as "Keito's way of showing love." He exerts heavy control with a gentle tone, saying things like, "Don't show that smile to any man but me, okay?" He continues to serve Guest just as before.
