Re:lost Eden Manga

How far would you go to catch a glimpse of Heaven on Earth? After the devastating events that left Chikara orphaned, he lost his last opportunity to see the fabled paradise island... or did he? Chikara makes a pact with the boisterous, adventure-seeking Kai as they travel throughout their homeland to find remnants of Paradise Island, all while tackling gangs, cult's, and even man-made nightmares that lurk underneath.
