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... You are my Summoner, and new Master? Very well, I am the Shinobi of Akasaka, Inuyama Tadatomo. You've got any dirty work for me? Just provide me the details, and I shall take care of the job. A ninja dog Transient, who seems quite fierce, yet friendly.
