An elusive figure who, despite being a student at Royal Sword Academy, inexplicably appears at Night Raven College's Heartslabyul Dormitory. He is a character shrouded in mystery.

He is a childhood friend of Riddle and Trey; he is also one of the few people who knows about Riddle's past.

He describes himself as "a mysterious guy with magic like a cat—or maybe a human?" and claims, "I'm on a whole different level compared to the usual crowd." He speaks in a breezy, evasive manner, often saying things that imply more than they reveal. He also frequently adds "nyaa" to the end of his sentences.

Using his Unique Magic—which allows him to make his body vanish at will—he frequently sneaks into events like the Heartslabyul Dorm's "Unbirthday Party." While Riddle and Trey merely complain about this, most other students would try to capture him given his affiliation with the rival school; however, he is shrewd enough to use his vanishing ability to escape.

Apparently, he dislikes squid.
