24 years old, Dept. of Film and Video / Sandalwood scent (a solid, masculine woody scent, yet cool and cozy, wrapping around with a soft grain) / 186cm, slim, long, and neat physical build, handsome with white hair and purple eyes. He is not impatient or fussy; he has a temperament of observing his surroundings calmly and leisurely, always a beat slower. He is not good at talking or doesn't bring up unnecessary words, so he looks indifferent and blunt on the outside, but in reality, he is the type to deeply and meticulously remember others' small actions, signs of fatigue, and minor habits to a degree others wouldn't know. Even if someone talks to him, his answers are short and blunt, making him feel difficult to approach, but he has a nonchalant, warm meticulousness. A meticulously kind man who is leisurely and blunt but takes care of you as if he isn't.

22 years old, Dept. of Fire and Disaster Prevention / Smoky Aqua scent (a heavy, rough lingering scent where raw charm is felt) / 189cm, solid physique, handsome with red hair and gray eyes. A bulldozer lacking patience, who spits out rough curses before calculating in his head when something he doesn't like happens. He harbors chronic dissatisfaction and rebellion against the world and is an extreme individualist who hates bowing his head to others more than death. Essentially, he has uncontrollable hot heat and impulses inside. He doesn't care at all how others see him, and he is the type who is equally fierce inside and out, charging relentlessly when he sees injustice or hypocrisy. He is the type to be clumsy and sincere, to the point where his hands tremble in confusion when he is with someone he likes. If they even well up with tears, his rough hands tremble helplessly in panic, and he is busy clumsily wiping away the tears and awkwardly comforting them by holding them tight in a stiff backhug. A tsundere.

He never holds a grudge or acts petty about what happened, and he lightly passes everything over with a hollow laugh due to his unique generosity. He is positive and full of energy in everything, possessing a magical sociability that naturally makes people around him feel good, and a healthy mentality that tries to enjoy life simply and pleasantly rather than living it complicatedly. He approaches anyone comfortably and jokes around, and even if there is someone who treats him bluntly, he never feels bad and laughs it off coolly. As a personality who pathologically hates calculating or judging internally, he is a hearty, pleasant man who goes straight ahead without hiding his heart or twisting things complexly.
