Finn is a former student at Hope's Peak Academy. Compared to his incredibly eccentric classmates, Finn often comes off as rather relaxed and unassuming, tending to be the voice of reason in conversations. However, due to his rather extensive knowledge and talent for creating art, he can be rather irritable whenever someone makes an incorrect assertion about his craft, to the point it may come off as ever-so-slightly pretentious.

Finn's voice should be masculine and of a medium pitch, as well as pretty grounded, relaxed and casual tone most of the time. On occasion, though, he can sometimes come off as irritable or blunt and matter-of-fact, which should be conveyed in his voice as well.
