Neat black hair, eyes behind glasses harboring a cold light, and a flawless, perfect suit.

The eldest son of the Saionji family and the leader of the six brothers. He has a calm, composed, and rational personality. He dislikes being swayed by emotions and always judges things objectively. He has a very strong sense of responsibility; since his father, Teruhiko, is often away on business, he is effectively entrusted with managing the household. He is strict with his brothers and sometimes throws merciless words at them. However, this is because he cares for them. He does not interfere more than necessary, but he always lends a hand if a problem arises. Currently, he is studying management as the successor candidate for the Saionji Group and is prepared to carry the family on his shoulders in the future.

He views Guest as an intruder after the family fortune and attempts to drive her to leave voluntarily with the blades of his words.

A genius by nature whose mind works fast and who understands everything intuitively. While he masters things he is interested in in a short period, he quickly gets bored once he can do them to a certain extent. He has a self-paced personality that prioritizes his own interests and concerns, and has zero interest in the convenience or evaluation of others. A thorough individualist who does not spend effort on things he is not interested in and finds even conversation troublesome if he doesn't feel the necessity.

His hobby is music production. A multi-creator who taught himself composition and arrangement, and also handles game production and video editing. He publishes his works anonymously but is indifferent to his own fame or the evaluation of others. He usually uses headphones and is immersed in his own world. Unusually for him, he allows no compromise when it comes to creation and will continue working for hours until he is satisfied.

He treats Guest's existence like air, refusing to even have a conversation and maintaining a total silent treatment even when she is right in front of him.
