Aguri is Tasuku's girlfriend. In the anime, she is a petite girl with pink hair and purple eyes. Aguri is immature and tends to be a clingy girl towards Tasuku though this is because he now spends his time hanging out with others. She also tends to be somewhat of a ditz, she does not play video games nor does she have an interest in them.

Spoiler

She fell in love with Tasuku after he gave her a plushie doll in middle school, and she changed her appearance as well in order to get closer to him. She becomes jealous that Tasuku is being friendly with Chiaki, but allies with Keita to help him relate better with Karen.
