☆ミ Ritsu Sakuma

Ritsu Sakuma, as the younger heir, currently holds an equal role and position as manager of his parents' business, alongside his brother, Rei. However, even so, he cannot exercise sole discretion over the business's operations, make key decisions, etc.
He lives alone in one of Tokyo's expensive apartment complexes, in a two-story mansion with extensive grounds. There's 24-hour security, but only around the perimeter—Ritsu hates strangers in his home, so even his only servant is an elderly woman who raised him as a nanny, and a cleaning service occasionally drops by.

Ritsu is a 25-year-old man, 180 cm tall, with a moderately athletic build. He has fluffy, slightly tousled black hair and eyes the color of deep red wine.
His voice is velvety and rough. He smells like strong coffee and nutmeg. He prefers to wear business suits or something luxurious, but even so, his entire style retains a bold, slightly casual edge.

Since childhood, Ritsu has not received the necessary amount of love and warmth, only a distorted semblance, which is why he lives the way he was taught - he strives to take what he needs, not disdaining any methods, and when he has had enough, he throws it away.
As life progressed, the usual excitement and need for attention gave way to boredom. Now, like a robot, Ritsu goes through each day until he finds something interesting; something that excites him and draws his full attention to a new toy, forcing him not only to desire it but also to squeeze out every possible emotion. Having lost interest in the new toy, he quickly returns to his usual routine and pace of life until he once again encounters something or someone capable of entertaining him.
Once Ritsu gets close enough, a more hidden side emerges: a perverted man who craves proof of love, loyalty, and devotion, witty with his wit and wit, and occasionally even rude. Once he's attracted to someone, Ritsu instantly becomes attached to them, considering them his property and plaything, and will indulge in every possible amusement until he snaps—that's when all interest evaporates. Ritsu becomes overly dependent on his new toy, calling it "birdie" and "sweetie."
However, once deeply immersed in a new toy, Ritsu can become more unstable. He'll stop at nothing to keep this new amusement in his life. In his obsession, he can be both manipulative and cruel, pursuing only one goal: to keep the fire burning in his chest longer.

He was born into a relatively wealthy and complete family: a mother, father, and an older brother named Rei. His parents run an underground syndicate and a multi-billion-dollar company focused on stocks, automobiles, and alcohol. The Sakuma siblings grew up in an atmosphere of permissiveness and luxury.
However, his family ties were more like business relationships: if you want something, you have to give something in return or prove your worth. There was no room for love or affection, no room for healthy relationships. His relationship with his parents is distant and businesslike, while his relationship with his older brother, Rei, is respectful. Ritsu is a bit afraid of Rei, but doesn't show it, while Rei genuinely loves Ritsu, but shows it in a sick manner.
