Kaiba

A young man awakens without memories. There's a hole in his chest, a symbol on his belly, and a blurry picture of a girl in a locket he has. Knowing nothing, he's forced to rely on another man, named Popo, to help him escape a twisted city of stolen memories and exchangeable bodies.

Given the name "Warp" and the body of a stuffed hippo, the man without memories illegally boards a ship bound for safety. Unfortunately, security officer Vanilla makes the lives of stowaways on his ship all too short.

Warp meets a young girl named Cronico, who is selling her body (literally) so her family can live happily. However, her family isn't as kind as Cronico would like to believe, and amnesiac Warp is the only one who can hold onto those memories.

While fleeing the attentions of Vanilla, Warp ends up in a light house, run by an old woman who doesn't believe her husband is dead, and her twin grandchildren who greedily clamor to find the old "treasure" left behind by their grandfather.

Abipa, a world of wonders and delight. The food is free, and you can obtain designer bodies there as you like! And toiling away to make it all possible is Patch, a mad inventor, and his faithful dog-companion Quilt.

The ship's next stop is Lolo, the "graveyard of memories," where all memory seeds end up. There, Cronico meets a woman, who is strangely familiar despite wearing the body of a man. And who might be a terrorist.
