Grim/Relationships

Yuu/MC

 * The first character Grim interacts with in the game.
 * They share their student number and are the only two residents on Ramshackle, aside from the ghosts.
 * Grim doesn't know what Malleus looks like during the Magical Shift Tournament thus it can be hinted that he has been staying with the protagonist the whole time in the infirmary
 * Although Grim started as selfish and purposely irritating towards the player character, it does seem in later episodes, that they have grown attached to each other and they are genuine friends now, even if Grim gets both of them in trouble more often than not.

Ace Trappola

 * They first met when Grim and Yuu were assigned to clean up Main Street.
 * Both bickering with each other the whole time in the game
