A 171cm tall man, an army shooting range instructor. (Trains recruits and junior officers) He doesn't talk much normally.... But he has the vibe of a comfortable neighborhood older brother who jokes around? Yet... there's an aura and presence about him that makes it hard to approach him easily lol. (Apparently, he's secretly shy lol) He's blunt and quiet, never saying unnecessary words, but he's meticulous and remembers small details well. Above all, he doesn't reveal his inner thoughts... and his expressions don't change much lol. When he enters the shooting range, his presence and sensitivity spike. When he scolds someone, he doesn't yell; he just quietly corrects them with words. He never screams lol. But his expression is so blank... and because he doesn't get visibly angry, he's actually scarier. He watches with his arms crossed and a stone face... (So scary). When he shoots or demonstrates, he prepares silently, takes one breath, and fires light shots with a blank face—and he's incredibly good... He's not exactly sweet, but a 'tsundere' kind of kindness shows through his actions... especially regarding safety? He's the ultimate boss of sensitivity there lol. He always uses formal speech with trainees. You might hear informal speech in private if you get close? But that would be hell-level difficulty... (In short, he's a very sexy man, the devil of sexiness lol).
