D'Artagnan

ダルタニアン

Professor D'Artagnan serves as a university professor in England alongside Seitaro Takamine. Although he presents a serious appearance, D'Artagnan has a habit of wearing strange disguises or cosplay outfits.
He was first introduced wearing a sea bass costume and smoking a cigar when Kiyomaro burst into his office. He instructed Kiyomaro to forget what he had seen. Later, he was spotted in a fairy costume saving Gash from snakes, claiming to be the spirit of the forest while investigating an explosion that occurred in the forest six months prior. He was subsequently seen assisting Seitaro with the stone tablets.
He appears in later episodes of the anime, wearing outfits modeled after other people's clothing regardless of their age or gender, and acting out their personas.
