Kei and Misora have known each other since middle school, when they first met on the school rooftop—an introduction Souma arranged. That encounter marked the start of their relationship, though Misora didn't fully trust him at first. Everything changed when Kei proved himself by using Misora's ability to save someone; after that, she completely trusted his judgment and decisions.
He's known for making quick calls and thinking fast on his feet when problems come up. Both in middle school and now in high school, Kei's been a regular fixture in the Service Club.
Kei's ability centers on memory: he can retain and recall details with unusual precision, even pinpointing small sensory specifics from past moments.
