Cage of Eden 18 features story and art by Yoshinobu Yamada.

Miina has been swallowed whole, but Yarai has a plan that just may save her and subdue the beastly Chimera that has brought chaos to Sengoku's camp. However, as good as Yarai's plan is, it may not be enough to deal with a new, surprising element that comes into the mix. With some ingenuity and a bit of luck, Sengoku and his crew have come this far, taking on all types of monsters on this mystery-filled island, but there still may be one beast that is more fearsome than anything they've ever seen before - something closer to them than expected.
