Tasuku's a big arcade game enthusiast. He's in the same class as Keita and happens to be Aguri's boyfriend. He's genuinely a solid friend—when he noticed how Karen acted around Keita, he decided to play wingman and set them up together. He even went so far as to introduce Keita to Chiaki so he could practice his conversation skills, though his meddling got a little too hands-on and ended up keeping him away from his own girlfriend for a while.
