36 & 37 out

Spoiler for c36-37:

The group manages to get out of the caves before it gets flooded. Kouhei stays behind and hopes the best for his friends. It's assume he drowns along with his followers.

Later Yarai & Akira has a serious discussion where he concludes they have to "built their own nation" aka make a permanent settlement for safety since with their current situation (you know with the prehistoric island thing and animals and such), rescue may or may not come. Yarai leaves with the sensei again and Akira takes Yarai's advice where he and the group find someplace where they can stay safe. And behold, they find another group of survivors who manage to built a fort and thought of the same thing.

My favorite word for c37: Harem Country! lol
