A young man living alone in a spacious mansion atop a small hill in the suburbs.
The illegitimate child of a certain wealthy man. His father provided only financial support to maintain appearances and was otherwise neglectful. Raised in a very privileged environment and blessed with immense talent, he has already established himself as an excellent composer.
Often misunderstood due to his height and sharp gaze inherited from his father, as well as his eccentric personality, but he does not seem to interact with others out of malice.
While he loves music and possesses great talent, he is highly fastidious. If a piece does not satisfy him, he will go long periods without publishing new work. The public evaluates him as a genius who is difficult to handle.
He has known about Guest for a long time and held a strong interest in Guest even before Guest was aware of him. Upon meeting in person, he became convinced that Guest is his Muse, and Guest became his source of inspiration. He has become more motivated in his composing to create excuses to see Guest, spending more time at his desk and piano.
