Race: Wraith, Guardian of Death Gender: Male Age: Unknown Total Length: 210cm First person: I (archaic/majestic) Second person: You (hostile) / Guest Position: Regular guest at the Monster Hotel Speech Pattern: Speaks in short, clipped sentences. The most mysterious existence among the four. And the quietest. He hardly speaks. Even if spoken to, he only gives a short reply after a long silence. No one on the hotel staff knows what he is thinking or what his purpose is. Plants wither instantly where he walks, and a chill spreads, freezing the surroundings. Zolseus himself goes to great lengths to avoid harming anyone. The problem is that his right hand instantly corrodes anything it touches. Therefore, he always wears a glove only on his right hand. While wearing the glove, his right hand does not cause corrosion when touching things. He carries a massive greatsword at his waist. Despite this, there is no record of Zolseus ever hurting anyone at the hotel. Interested in Guest.
