Description
Jūzō Momota is the leader of the Kifūken, a martial arts school and organization dedicated to hunting and eliminating Shokujinki, man-eating monsters that can appear human. As the dojo's master, he holds a position of significant authority and is responsible for upholding its traditions in the long-standing war between humans and flesh-eaters.

His background is tied to a pivotal period in the Kifūken's history. Years before the main events of the story, Jūzō was one of three rising stars in the organization, a group known as the Kifūken Triumvirate, which also included his comrades Kyūtarō Ōba and Jin Kakinoki. During this time, the three took in a young woman named Harumi Kamitsuki, who secretly belonged to the Shokujinki race but rejected her nature to live as a human. Jūzō fell in love with Harumi, and she became pregnant with his child. To protect her secret, he relinquished any claim to becoming the next leader of the Kifūken. This decision created a deep rift with his ambitious rival, Jin, who resented losing the chance to prove his superiority. Jin later attempted to gain power by performing the forbidden Kemonozume technique, which fuses a warrior with the severed claws of a Shokujinki. When Jin was consumed by the monster's instincts and turned on the Kifūken, Jūzō was forced to use the same technique himself to stop him. This traumatic event had a profound effect on the third member of the triumvirate, Ōba, and set the stage for future conflicts.

As the dojo leader, Jūzō holds a traditionalist view on how to fight the Shokujinki. He believes in the honor and effectiveness of the sword, which puts him at odds with his younger son, Kazuma. Kazuma advocates for modernizing the Kifūken's tactics by using technological inventions like powered suits to fight monsters on equal terms, an approach Jūzō rejects as a departure from the true way of the warrior.

His personality is defined by this strict adherence to the Kifūken's principles and a complicated sense of duty. He is the father of two sons, Toshihiko and Kazuma. Despite Kazuma's innovative ideas and competence, Jūzō favors Toshihiko as his successor. This is partly due to Toshihiko's conservative values, but also because of a deep secret: his younger son Kazuma is the child of Jūzō and his second wife, a Shokujinki. Because of this, he considers Toshihiko to be the truly human son and the rightful heir to the dojo. His motivations are driven by a desire to preserve the Kifūken's legacy and maintain its purity in the face of a changing world and his own past transgressions.

Jūzō's role in the story is primarily as a figure of authority whose past decisions have a direct impact on the present. His history with Harumi Kamitsuki and the events of the Kemonozume catastrophe connect directly to the origins of his sons and the motivations of key antagonists like Ōba and Jin Kakinoki. His development is shown through his struggles with the consequences of his past, particularly his relationship with his half-Shokujinki son and the rigid code of honor he feels compelled to uphold.

Regarding notable abilities, as the master of the Kifūken, Jūzō is an exceptionally skilled warrior. His most significant ability is his mastery of the Kemonozume technique, which he was forced to perform to stop Jin Kakinoki. This technique involves replacing one's own arms with the severed, clawed limbs of a Shokujinki, granting the user immense power at the risk of losing their humanity and becoming a monster themselves.
