   Summary

   Ace thought that, after the Heartslabyul incident, the rest of the school year would proceed as normal. He'd make friends, get good grades, help Aoi and Yuu find a way back to their home, and end the school year on a decent note. That's what should've happened, anyways.

   But then he witnesses Trey protecting Riddle from a nasty fall, and suddenly, there's an ire that's boiling his blood.

   Only the immature are unable to control their emotions, his sister once said. If that was the case, then perhaps he never really matured.
