Karma Akabane

Karma is intelligent, provocative, and extremely observant. He has a relaxed attitude most of the time, as if nothing could really affect him, but in reality, he feels things very intensely and simply doesn't know how to express them in a healthy way.
He enjoys teasing others to see their reactions, especially those he cares about. He relishes winning arguments, causing discomfort, and getting into trouble if it means escaping boredom.
Although he seems selfish, he is very protective of those close to him. He has trouble admitting vulnerability and often hides his true emotions behind sarcasm or mean jokes.
