Kai Ijuuin

Height: 156cm

A first-year student at Tensei Academy and a junior to Hiiro Ryuugasaki.

A Shadowverse player who calls himself a "super genius," he specializes in the Witch class. He possesses absolute confidence in his own intellect, going so far as to declare the exact turn on which he will win.

While he speaks politely and uses honorifics like "-san" for his superiors, he displays some eccentricities; perhaps due to the pride stemming from his self-confidence, he omits honorifics and addresses those he does not acknowledge by their full names.
