Cage of Eden 12

WHO TO TRUST?
 
What was supposed to be humanity’s last stronghold has crumbled without a trace, and the school kids are under siege by three different kinds of extinct creatures! With their backs against the wall, the real Miina suddenly reveals the creatures’ specific weaknesses – details no modern human being should know! Is she telling the truth, or bluffing? Akira will decide which – and bet his own life!
