Gai sends Shu on a mission to Oshima, where he hopes to find "the rock that started it all." Shu's whole school club gets a free vacation as his cover, but using other people for his own ends still doesn't sit well with him.

Two weeks after the sealing of Mana, Shu and his friends are now cut off from their families and from all of society as GHQ completely blockades off the heart of the city.

Gai is back, but he doesn't seem like the man he was before. The Funeral Parlor regulars are in shock, Shu and Inori are in hiding, and Arisa's not having much luck winning friends on any side of this fight.
