Sumito Kayashima

Sumito is the 26-year-old head of the Kayashima family. He went to university but doesn't work, because the insurance payout from his parents' accidental death can support his life of luxury. His main hobbies are playing chess and collecting antiques, but he also enjoys social dancing and horse-riding. Sumito doesn't speak much to people he doesn't know very well, but is very straightfoward and honest to the Gardener, though at times he tends to keep his doubts to himself, causing misunderstandings.
