Sho is a Reaper Officer, and is the GM in Week 2. He is 18, making him the youngest GM in Shibuya. Also, he can't refrain from making a calculation/math joke.
He can summon Taboo Noise that attack both Reapers and Players. Sho learned these techniques from Sanae Hanekoma.
His noise form is Leo Cantus. He transforms by absorbing Taboo Noise around him. After his defeat, he comes back in Taboo form, and wants to become Composer.
I know that my avatar is a girl, it's called "crossplaying".
