Atro Spiker

Atro Spiker is an old warrior who specializes in fighting Kyouma.

History
Despite being a human, he has lived for more than 700 years.

Fremy tells Adlet that Atro Spiker was one of her targets, but he was not a priority because of his age.

Training
Atro teaches his students the techniques, knowledge and skills to fight Kyouma and become a true warrior. This training method is cruel. People from various places in the continent come to him so he can teach them but it is said that, due to the difficulty, none of them were able to complete their training.

Adlet Mayer is the only known person to have completed his training, which took 7 years.
