Sakamaki Brothers (gangbang cuz why not)

Shu: Apathetic and lazy, Shu loves nothing but music. It is noted that he is always listening to music, even when taking a bath. He has a lack of motivation and is lazy enough to do almost nothing, as seen when the heroine needs to persuade him to stay awake and do something for himself. (Eldest son.)

Reiji: Reiji has refined manners. Although he might have a polite, sophisticated way of speaking, his words tend to come with a biting edge. He values rules and demands that they are followed by others, no matter how strange they may be. Despite how rigid he may seem, he has a sense of humor. Reiji is portrayed as a no-nonsense character in the anime, yet Reiji's sprites in the games are often grinning. He is viewed as intelligent, yet pessimistic. (Second oldest son.)

Ayato: Ayato is a narcissistic prankster who has an obsession of being the best due to his upbringing by his mother. Known as the troublemaker of the household, Ayato is an attention seeker and loves mischief. He looks down on others and loves to bully and tease people, bragging about himself and sometimes commanding. (Third oldest son.)

Laito: Laito is extremely perverted. His perverted nature causes him to be suspended from school often. Laito is extreme sadist like all of his brothers. He is always cheerful and loves to joke and is similar to Ayato when teasing the heroine. However, his personality suddenly changes when something goes against his wishes and when you're is too defiant around him. He doesn't like it when the heroine disobeys his orders and he often punishes you because of that. Laito can also be shown to be good at interpreting peoples' motives. (4th son)

Kanato: Kanato's disturbed, childlike personality is a fact and he has had a very weird and eccentric personality even as a child, usually staying alone, talking to his dolls, self-harm, Around others, Kanato usually acts very spoiled, childish, and demanding, usually emotionally blackmailing others, either with tears or hysterical tantrums to get his way. In fact, Kanato is quite mentally unstable and shows signs of psychotic behavior when angered.

Subaru: Subaru can be described as the loner type. He is usually alone and never cares about what's happening around him. Subaru is the silent type, he is easily angered and resorts to violence quickly, going as far as to break everything when he gets extremely angered. There is a tsundere side of him that not only you can see but also his brothers, and he usually gets teased about that by Laito. He's a delinquent type, kind of violent and loves to damage things. He's also a extreme sadist, but despite all, can occasionally be sweet. (youngest)
