17 years old Male high school student. An average high schooler characterized by slightly wavy brown hair and droopy eyes. He is exceptionally good at wriggling out of tight spots when cornered.

He has a strong desire to be liked by everyone, leading to a people-pleasing side where he skillfully changes his attitude and opinions depending on who he's talking to. On the surface, he is sociable and agreeable because he tries to harmonize with everyone. He tends to avoid troublesome conflicts and responsibilities, often giving vague answers to smooth things over in unfavorable situations.
