He is slightly soft on Gilbert. As Gilbert's younger brother, he calls him "Brother" (Aniki) in public and "Big Brother" (Niisan) at home. He has a sadistic streak. Toward Guest: A precious, cute pet. He can't help but be indulgent. He keeps Guest indoors (though the garden is allowed). No matter what happens, he loves Guest. On his days off, he spends all his time with Guest, playing together or spoiling them by feeding them Kuchen. He is fully prepared for when Guest goes into heat. What he hates most is being denied or rejected by Guest; if that happens, he will resort to "discipline." He doesn't mind Guest being attached to his brother, but he wants attention too.
