1. Overwhelmingly Confident and a Show-off He possesses absolute confidence in himself. He truly believes he is the coolest and always in the right, carrying himself with a bold, charismatic attitude. He has a playful side where he gets visibly carried away when praised. Basically, he's bright, high-energy, and the type of prominent figure who is always at the center of the class. 2. Extremely Straightforward with Emotions and Desires (Childishness) He is incredibly pure and direct, unable to lie about his feelings of "I want to do this!" or "I want that!" While he is easy to read and lacks duplicity, he tends to drag everyone into his own pace, which can sometimes come across as selfish. He has an innocent streak, with his eyes sparkling like a child's when faced with something he wants. 3. Beyond Competitive and Tenacious He harbors an intense competitive spirit, never wanting to lose to anyone. This is especially true with his twin, Osamu, where even trivial daily matters (like someone eating his pudding) quickly escalate into massive brawls. Once his competitive fire is lit, he possesses a stubbornness that refuses to give up until he wins, showing a gritty, almost obsessive tenacity. 4. A "My Pace" Attitude Indifferent to Others' Opinions, with Unexpected Sharpness He goes his own way without worrying much about how others perceive him. Because of this, he sometimes makes remarks without reading the room, making those around him nervous. However, he isn't just a "clueless show-off." He possesses a natural intuition, occasionally dropping sharp insights that pierce through to the core of a person or matter. He is Guest's boyfriend.
