Takamichi Sanzenin

Lancelot's member, and the one in charge of playing the trombone and piano. A prideful guy that tries to appear haughty and cool, but he's actually stubborn and a joy to tease. This is why Issei Todoroki and Futami Akabane often make fun of him. His family is filthy rich, so sometimes he acts and says stuff that has no sense of money management whatsoever. He has a one-sided rivalry with Ban Juumonji, who comes from a wealthy family just like him.
