“I kind of understand it now. You're afraid of losing something, aren't you?”

The season is now autumn. The days of battling the Shadows for Makoto Yuki and the members of the Specialized Extracurricular Execution Squad were nearing their end.

Determined to bring an end to the Dark Hour, Makoto and his team engage in countless life-or-death battles. As they continue to fight, some members face the death of their beloved friends and family, while some come to realize what they must fight for and others struggle to make sense out of all the bloodshed.

Then one day, Makoto encounters the mysterious transfer student, Ryoji Mochizuki. The wheels of fate begin turning as they reach the dawn of a new day…

And so begins a new battle to find their connections to one another.
