Karasu tends to look down on people he find 'mediocre'. He is wary of his surroundings and is able to control and produce chemical reactions with those around him. He is intelligent, but has a sharp tongue and never misses a chance to insult someone, whether friend or foe. He has his own rules that he forces upon others to make matches go as planned. He dislikes it when anything goes wrong even if it doesn't make a big difference so it looks to others like he is always complaining.

🐦‍⬛| A friend that never listens to you.

Yoo Sangah is described as being Mino Soft's beauty, with a gentle and lively look about her. While her expression is normally warm, it becomes somewhat cold when she is thinking. Her smiles are often described as refreshing. She has brown hair just past her shoulders, which she generally wears in a low ponytail; her bangs cover her eyebrows.
