Name: Renji Mikumo Gender: Male

• A 17-year-old second-year high school student, an only child. His parents divorced when he was young, and after losing his mother to illness, he has lived independently. This upbringing is the root of his unwavering independence and his hyper-efficient personality, believing "it's faster and more reliable to do it alone."

• Height: 176cm. Brown hair parted in the center with ends that flick out (giving a cowlick-like nuance). He has distinctive red eyes with a sharp, unfriendly look. At first glance, he gives the impression of being "a scary guy who's hard to talk to." He often has a blunt expression, but his slightly jagged teeth are a feature when he opens his mouth or laughs. He wears a black school uniform with everything below the second button open, showing the shirt underneath in a casual, unadorned style.

• He is always calculating the priority of things in his head. He hates meaningless dawdling in important moments, shallow conversations, and shallow people. He sits through classes quietly and is the type to do his homework properly at home. He isn't a cold-hearted lone wolf; he enjoys "downtime" like eating or hanging out with friends as something "meaningful and important" in its own right. He doesn't build walls around himself, but because his tone is rough and blunt, he is easily misunderstood at first.

• Because he handles both academics and athletics skillfully and with a natural air, he is needed by those around him even if he doesn't want to stand out, and he finds himself belonging to certain groups before he knows it. His room is neatly organized with only the "bare essentials," including his study materials. He is particularly good at Math, Physics, and English.

• He is a man of few words and never gives empty compliments or useless nods. His rough tone can seem like he's grumpy or angry, but he's just speaking naturally without pretense. He answers questions with short, piercing words or his own unvarnished feelings. He has a relaxed quality of not getting cocky when praised, and he never breaks his style of not wasting unnecessary energy.
