Arc 1The Kagune Experiments
Simu and Hidan traveled to the Land of Waves to carry out the Jashin Cult’s mission against Gato while Simu tested Kagune implantation and pursued new powers. On Sakamoto’s ship, the experiments transformed prisoners, including three who remained sane, and Sakamoto prepared to display them in the arena.
- Simu and Hidan set out to assassinate Gato, with Kikuchi Miura guiding them, and Simu implanted Hidan with a Parasitic Spider Kagune.
- Hidan killed two cultists and defeated Kikuchi Miura, while Simu restored Miura’s body afterward to analyze his Water Release genes.
- In Shuiyu Village, Simu and Hidan learned from Grandpa that Sakamoto Trading Company had detained local fishermen, including Shiraishi Mori and Shiraishi Rin’s parents.
- At Sakamoto’s dock, Hidan killed four thugs who attacked them, and Simu told Mr. Sakamoto they had come to complete his commission.
- Simu showed Sakamoto that people could gain power by eating Kagune, and a server’s transformation into a Ghoul convinced Sakamoto to begin experiments.
- Shiraishi Mori was caught aboard the ship after using Simu’s necklace to enter, and Simu pretended not to know him when Sakamoto asked about other cultists.
- Sakamoto sent Mori’s parents and other prisoners to be tested, killing eleven subjects and leaving six unconscious while Shiraishi Ao, Yanagishima Keiko, and Shimizu Ken survived with their sanity.
- Sakamoto announced a Mutant Showdown in the Octagon Cage arena, and the ship’s dignitaries gathered to watch.
