Isurugi, Jin

He is a third-year student who is the head of the school's elite anti Metaphysical fighters called the Swords of Salvation. He recruited Moroha to be one of his Strikers after seeing his fighting skills. Though Moroha's has fought his brother, he never took it personally and was in fact fascinated as to how he was able to defeat him. He also recruited Urushibara to be one of his reserves upon her elder brother's recommendation, since her brother happens to be the school president and later on Ranjou who has displayed courage upon encountering a hydra metaphysical despite of being in a disadvantage.
