Just as I’d hoped, Satomi and Enju reunite quickly, when she goes to school again, trying in vain to fit back in. But the truth is, none of the kids at that school are her friends anymore; they’re too blinded by hatred of anything to do with the Gastrea. She’d refuse to give in, but it’s no use, and and Satomi knows it, which is why he suggests they change schools; start over where the kids don’t know what she is, because frankly, it shouldn’t matter.
Still when Satomi and Enju are helicoptered to the location of the Gastrea with the case, Enju exhibits superhuman powers that are always going to turn off or frighten “normal” humans. Little girls aren’t supposed to be able to leap out of helicopters and kick giant spiders into a fine paste. Indeed, the bitterness of having her normal school life sabotaged seems to fuel her attacks. It looks like Mission Accomplished…until Kagetane and Kohina show up.
Satomi is roughed up badly, run through by katanas, and launched off a cliff into a river to die. Had he been a normal human like I thought, he would have died. But we learn the creepy sensei who eats terrifying-looking food did…something to Satomi years ago, and as a result, he’s…something more than human, much like Enju, which explains why they get along so well. They’re bound not just by the promoter-initiator contract, but by the fact they learned to become human together. They’re family.
The same can’t be said of some other pairs; notably Ikuma Shougan and Senju Kayo, with the former treating the latter as nothing but a tool, and Kayo following orders, even those to murder other Civil Officers so Shougan can get to Kagetane first. When Satomi and Enju find her wounded in the woods, she admits to feeling like there’s “something wrong with her” if she’s okay with such killing, and that she envys Satomi and Enju’s bond.
Of course, with that cushy bond comes great responsibility: it’s entirely possible they didn’t meet by accident, and despite not ranking high on the official scale, it’s hinted that the two of them are the only ones who can stop Kagetane from summoning a city-destroying Stage Five Gastrea. despite how briefly they lasted in their last battle. Also adding texture to the proceedings is the mention of zealots who consider the Gastrea God’s punishment for the sins of mankind; and the cursed children as messengers between the two; Angels, in other words.
