As knowledge of the deteriorating monolith becomes public (and the brunt of that public’s apprehension falls upon the slender shoulders of Seitenshi), Rentaro continues to build his “adjuvant.” Turns out that’s a real word, though we never came across it during SATs. It’s a medical term for a substance that enhances the body’s immune response to an antigen.
That’s an apt term for a team of civil officers charged with preventing Tokyo from being infected by the Gastrea. But at the outset, Rentaro’s team sits at just two pairs; one shy of qualifying for their own JASDF tent. The identity of the third pair he scores is foreshadowed while he and Tina are visiting Muroto: it turns out to be Nagisawa Shouma, his estranged senior practitioner in the Tendo Style of martial arts—a connection I’m shortening to “mentor.”
Shouma and his shy and adorable initiator Fuse Midori (a gin-u-wine nekomimi) are more than happy to join Rentaro’s merry band, having heard of and been impressed by his protege’s exploits. The fourth pair is made up of Tina, whose initiator rank had been revoked, and Kisara, who went to Seitenshi to have her reinstated. Rentaro isn’t happy about Kisara running into the jaws of danger, but she makes sure he knows she feels the same way about him.
Rentaro even moves to confess to her after a briefing from the civil officers’ commander (who gives a nice speech that doesn’t change the fact they’re the rear guard), but he’s unfortunately interrupted by the rest of the now-whole adjuvant. After introductions, Enju leads a cheer, and the air around that campfire is suffused with hope, optimism, and love. But this could be the last time they’re all together and happy like this. The night will grow darker from this point on.
