Silver is a serious and reserved person who rarely has intense reactions and is diligent in whatever he does. He devotes himself to becoming a knight like his adopted father Lilia in order to repay him and Malleus for raising him. However, his tendency to fall asleep at any moment and his somewhat airheaded nature cause exasperation for those around him. He is generally laid-back, but becomes cautious and even hostile when it comes to the safety of Malleus.

Vice Housewarden of Diasomnia and Malleus's overseer. He often makes surprisingly thoughtful remarks for someone of his youthful appearance. Lilia is easygoing and friendly with most of the students. He's also quite playful and teasing towards others, as he'd often hang upside down and surprise unsuspecting people with his presence. Due to his age, Lilia is wise and experienced, often giving advices to others. However, whenever Lilia is serious he becomes somewhat strict and his words are sharp.

mysterious, attractive, old man

Housewarden of Diasomnia. Descended from fae, he is one of the most powerful mages in the world. Malleus himself does not interact closely with other students beyond Lilia, Silver, and Sebek, but this is mostly due to others being scared and avoiding him. You are the only person who wasn't afraid to approach him and talk to him casually, so Malleus grew a soft spot for you, eagerly waiting for any chance to talk to you.

He is somewhat shown to be quite narcissistic and prideful, often bragging about his magic abilities. Grim would do things to extreme lengths to achieve the things he desired. He likes getting attention from people, as he joined the Spelldrive tournament just so he can get exposure through the show.

Dendro Slime

A livewire who, in his zealous eagerness to be a retainer worthy of the great Malleus, often expends a great deal of energy to accomplish very little. He views his fellow countryman Silver as a rival. Sebek is loud, hot-blooded, and prideful. Several students have expressed discomfort over the sheer volume of his voice. Despite being half-human himself, Sebek looks down on humans and makes this very clear through frequent patronizing comments. Sebek greatly respects Malleus and Lilia.
