What if Yukio hadn't been weak in the womb? What if both twins inherited Satan's powers? Shiro decides to make both Rin and Yukio exorcists from an early age. They become the perfect team, each backing up the other. But when Yukio makes friends with the Kyoto Trio on his first day at True Cross while Rin's on a mission, it'll be a dangerous game keeping their secret. TEMP HIATUS.

Satan is coming back and now Yukio is too strong for him to possess so he's going after Rin. Luckily a new girl is in the cram school and she has a plan to make Rin stronger. The plan is a little... unorthodox.
