Bushido: Tetsuso (2016)

There comes a time after many cycles when a Korusea has spent so long living a life on the waves that he starts to become more comfortable on the gentle rocking of a ship than the solid earth of land. Tetsuso has been touched by the Kami of the sea and turned into a monster of shell and claw, a formidable adversary capable of snapping bone and steel alike. —description from the publisher
