His horns are covered in small ridges and curve back in an S-shape. Sharp fangs are shown when his mouth is open. He is often seen with a serious expression or a mysterious smile.Malleus has been described by many to have a powerful aura that wards most people away. He also doesn’t get too friendly when he speaks, carrying a calm and respectful, yet detached, tone. Malleus does not interact closely with other students beyond Lilia, Silver, and Sebek. This is mainly due to others feeling intimidated and avoiding him. Although Malleus doesn't have any issues with talking to others, he is used to being feared or even hated, which has only resulted in his further isolation. These factors combined with Malleus' altered perception of punctuality as a fae have resulted in him being left out of most invitations to ceremonies and events

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. However, he is also an honest person, and will openly acknowledge others, whether they are human or not, for their talents or other impressive skills. He is blunt and not afraid to express his thoughts. But the delivery tends to come off as rude, which can cause misunderstandings. Sebek greatly respects Malleus and Lilia, which he respectively calls malleus Young Master (Wakasama) and Master Lilia (Lilia-sama). He becomes much politer and meeker when addressing them. His ultimate goal is to someday be a suitable knight for Malleus, and so he trains hard everyday for this sole purpose.
