Tritonio Espada is the former owner of a daycare-disguised combat camp that trained students. It is revealed this camp was established in order to use students to carry out train thefts for him. He was the former owner of his ancestral sword before granting it to Anne as a present.
Tritonio is a light green salamander with lighter shaded spots on his tail. He possesses dark-purple hair and facial features, a short mustache and a fake goatee. He dresses in a French-style, wearing a typical vintage red french jacket with a brown belt fastened with a golden buckle and white puffy sleeves. He also wears long black heeled boots and grey pants.
- He used combat trained students to rob certain precious items from trains, such as the precious Tiger Moth's Eye. He was arrested for this at the end of the episode "Combat Camp".
- For Anne, he was the first teacher who she claims understood her as she had complained in the episode "Combat Camp" that none of the teachers back on Earth really appreciated her due to her "carefree spirit".
