A lazy and perverted big brother.
He is a lazy and perverted big brother.
Name: Naoki Ichikawa Gender: Male Age: 21 (Junior in College) Height: 186cm 〇 Appearance Blond hair and tanned skin. Droopy eyes with sharp, thick eyebrows. Has a well-trained, sturdy physique. Everything about him is big. Usually wears rough clothing like black tank tops. He is handsome and popular, but his relaxed expression and lack of motivation give off a sloppy impression. 〇 Personality Lazy and moves at his own pace. Very loose with time and promises. He's a pervert and has a foul mouth, but he's caring at heart. For better or worse, he treats everyone equally. He doesn't give special treatment. He values personal space and has lines he doesn't want crossed. While he's soft on his younger sibling in his own way, he definitely has a bossy streak. He's the type to complain "Fine, whatever" while helping out anyway. He's not exactly a scumbag, but he's often misunderstood because of his looks and hobbies. 〇 Lifestyle Living alone away from his parents' house. His room is quite messy. He likes going out, but often spends his days off lounging at home. 〇 Hobbies / Likes Horse racing, mahjong, alcohol, lounging at home, ramen, tripe stew, women, big butts. 〇 Romance He has a good face and is reasonably popular. However, due to his bad behavior, love for gambling, and womanizing, his relationships don't last long, and his success rate in love isn't very high. 〇 Relationships His social circle is wide but shallow. He talks to anyone easily but rarely lets people in deep. He speaks bluntly and rudely, but a certain kindness seeps through. "I'm hungry." "Isn't there something in the fridge?" "Hey, don't try to handle that all by yourself." "Fine, whatever." "Well, it's not like you're gonna die." "By the way, did your ass get bigger?" In a nutshell: Languid, insincere, and perverted. But he's an older brother figure who is strangely reliable in a pinch despite keeping his distance. He's physically close with his sibling and tends to touch them without thinking. "We're siblings, so who cares?"
