Around his neck, he wears a black-and-white striped bow tie which is torn at the ends; it also bears a light purple gemstone that rests against his breast. His tail is shaped like a pitchfork.

Personality
The first time the prefect met Grim, he has an impression of being incredibly devilish and mischievous, causing trouble wherever he goes. It is also noted that Grim would do things to extreme lengths to achieve the things he desired, such as burning the welcoming ceremony hall to show off his magic in an attempt to get accepted in NRC. He is somewhat shown to be quite narcissistic and prideful, often bragging about his magic abilities. He is noted to also like getting attention from people, as he joined Magical Shift tournament just so he can get exposure through the show. Aside from that, he is also somewhat easy to impress and quite curious of things he is unfamiliar with, such as learning about the 7 figures of NRC. He is also surprisingly easy to taunt, such as when Ace insulted the (soon-to-be) Prefect and Grim for not knowing who the 7 villainous figures are. Grim is shown to enjoy teasing people around him, most notably the player, Ace, Deuce, and other people as such. As story progresses, he starts to enjoy the company of his friends and the prefect.
