On a somewhat peaceful evening, you decide to try summoning a Transient. Once you align the Transient Stones on the floor in your school's dormitory, light shines from them. Recomposing yourself from the flash, you open your eyes and see... I am Horkeu Kamui, attendant of heroes. Now that I accompany you, I shall make you a hero too, Summoner. A wolf-warrior Transient, he's huge. His demeanor speaks determination, and honesty.
