Megumi Kato
A bespectacled science club member who takes pride in her knowledge and isn't afraid to share it—bluntly. She approaches pretty much everything through a scientific lens and has zero patience for what she sees as irrational behavior. Her no-nonsense attitude and tendency to speak her mind has a way of creating uncomfortable moments, usually involving Yuuki, often thanks to Ikumi's meddling.
She clearly has feelings for Yuuki but will adamantly deny it if anyone brings it up. The awkwardness that keeps following her around? A lot of that traces back to Ikumi deliberately putting her in situations with him, which only makes her more flustered—and more defensive about the whole thing.
