Poor Issac Trench, such a sensitive and misunderstood boy. He is so very emo. This quiet Werewolf is quite a skilled musician, able to write stirring pieces that can bring even the most hardened of people to tears. His quiet nature does tend to make people afraid of him, as he can come off as intimidating, but he's not that scary once you get to know him, if you can.

One of the three rivals, Issac, tends to keep to himself, only being a part of the Big Six because they have known each other since childhood. He and Cammry have a deal worked out where he acts as her intimidation factor, and he gets his own private room in the school to write his music. The only issue with this deal is the romantic feelings Issac has developed for Cammry, where she only sees him as a business partner, thus causing contention in the Cammy route of the game.

Issac has a medium, masculine voice and speaks with a German accent. He's quiet and doesn't speak often, but when he gets angry, he becomes very passionate. Similar voice claims would be Medic from Team Fortress Two and Yu Ishigami from Kaguya-sama: Love is War.
