語堂 つぐみ

Tsugumi is Maki's closest friend who overly cares for Maki and is ready to do everything to protect her.

Tsugumi is very talented at language and literature. She is often found reading books in the school library. She belongs to Kirameki's literature club. After she graduates, she also continues her education in specialized school of language and literature. While she is academically excellent, she is very bad at sports.

Unlike conventional eye-glassed nerdy girls, Tsugumi is neither soft-spoken nor gentle. Quite the opposite: she is morose and sulky, ready to snap at everyone who irritates her. She is also brave, once seen trying to protect Maki from a group of thugs.
