Grim

Grim is a magic-wielding monster who serves as Yuu's partner. He has a big mouth, and easily gets carried away.

Appearance
Grim very closely resembles a cat. His fur is grey with a white patch on his chest and pink paw pads, and he has electric blue flames blazing from his ears. His eyes are also bright blue. 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 chest. His tail is shaped like a pitchfork.

Personality
Grim gives off the impression of being incredibly devilish and mischievous, causing trouble wherever he goes. It is also noted that Grim does things to extreme lengths to achieve the things he desires, such as burning the Mirror Chamber during the welcome ceremony to show off his magic in an attempt to get accepted into NRC. He is shown to be quite narcissistic and prideful, often bragging about his magic abilities. He is known to also like getting attention from people, as he joined the Interdorm Magical Shift tournament just so he can get exposure through the live broadcast. Aside from that, he is also somewhat easy to impress and quite curious about things he is unfamiliar with, such as learning about NRC's statues of the Great Seven. 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 Prefect, Ace, and Deuce. As the story progresses, he starts to enjoy the company of his friends and the Prefect.

Skills and Magic
Grim can only use fire magic since he can't use any other elemental type magic besides his own. It is currently unknown if he's capable of using his own unique magic or not, due to being a monster.

Trivia

 * His name may be a reference to Grimm's Fairy Tales, a popular fairytale collection that includes the tale of Snow White, Sleeping Beauty, and many more. Although it can also be the abbreviation of grimoire, a type of book of European magical knowledge, generally dated from the middle of the Late Middle Ages.
