Description
Kai Shimada, alternatively known as Shimada Kai, held the rank of corporal in the Shinsengumi's Second Unit. Born Kondo on January 5, 1828, in Ogaki domain, Mino Province, he later adopted the Shimada surname following his adoption by an Ogaki clansman. He trained in swordsmanship at Edo's Shinkata-ryu Tsubouchi Shuma Dojo, forging a lasting friendship there with Nagakura Shinpachi. Shimada possessed an imposing stature, standing approximately 182 cm tall with a heavy build, and was renowned for exceptional physical strength. Despite this formidable presence, he abstained from alcohol while harboring a strong preference for sweet foods, particularly bean jam rice cakes.
He joined the Shinsengumi circa 1863, initially operating as a spy before advancing to the role of inspector. His duties encompassed intelligence gathering, enforcing regulations, and conducting internal purges under Vice-Commander Hijikata Toshizo. During the 1864 Ikedaya Incident, he aided in apprehending Kotaka Toshimaro and later attained the rank of sergeant after the group's reorganization. Shimada participated in pivotal events, including escorting Commander Kondo during an 1867 attack by remnants of the Goryo-eji, where his intervention saved Kondo's life by diverting the assailants. At the 1868 Battle of Toba-Fushimi, he utilized his strength to rescue Nagakura from enemy fire, pulling him to safety over an earthen wall during a retreat under heavy gunfire.
Shimada maintained unwavering loyalty to the Shinsengumi throughout the Boshin War. He followed Hijikata to Hakodate, serving as a bodyguard and later commanding the Shuei Shinsengumi unit during the Battle of Hakodate. After the Shinsengumi's surrender in May 1869, he lived in seclusion until his release in 1873. Declining offers from the Meiji government due to his steadfast loyalty, he took menial jobs in Kyoto, working as a sales clerk and night watchman at Nishihonganji Temple, the Shinsengumi's former headquarters. He opened a kenjutsu dojo in 1876, though attendance declined by 1886. Shimada died at age 73 on March 20, 1900, while employed at the temple.
Within the anime series, Shimada features across multiple seasons. In the first season, he works undercover as a spy alongside Susumu Yamazaki, participates in battles within Nagakura's squad, and aids in protecting Chizuru Yukimura from Kazama. He survives the Toba-Fushimi battle as one of the few remaining members of his unit. His role expands in the second season following departures of key figures like Sanosuke Harada and Nagakura. He handles critical missions for Hijikata and Kondo, aids in Kondo's sacrifice to facilitate others' escape, and later rescues Hijikata from Utsunomiya Castle. He observes shifts in Hijikata's behavior, alerting Chizuru to these developments. During the Imperial Army's Hakodate attack, he fights alongside the Shinsengumi but is cut off from outside support; his ultimate fate is implied though not explicitly shown.
In the prequel series *Reimeiroku*, Shimada joins the Roshigumi in Episode 6. He recognizes Nagakura from their shared dojo past and is appointed as an inspector alongside Yamazaki by Hijikata, tasked with internal and external investigations, though his appearances are primarily limited to delivering reports.
Visual novel and game narratives depict Shimada as compassionate and duty-bound. He reassures Chizuru during her search for her father, emphasizing kindness as integral to a warrior's honor. In one sub-route, he assists Chizuru and Hajime Saito in capturing a troublesome cat and later comforts the child who owned it. His interactions demonstrate loyalty to superiors and discomfort with excessive praise. Within *Edo Blossoms*, he survives to inform Chizuru of Hijikata's fate in non-Hijikata routes or requests she care for the commander in Hijikata's route.
