Kakucho/Relationships

Takemichi Hanagaki
Kakucho and Takemichi were childhood friends. After Kakucho was beaten by a group of older kids, Takemichi promised to get revenge for Kakucho. Although Kakucho declined, saying that he needed to get stronger, Kakucho saw Takemichi as his childhood hero. Because of this, Kakucho asks Takemichi to help save Izana from darkness.

In his fight against Takemichi, Kakucho says he prioritizes his devotion to Izana over his childhood friendship with Takemichi, threatening to kill him. After witnessing Takemichi's unflinching determination against Tenjiku, Kakucho comes to respect Takemichi even more, wanting to recruit him to Rokuhara Tandai. He is also unsurprised by Takemichi's new goal of defeating Mikey, having already witnessed his drive.

Izana Kurokawa
Izana encountered Kakucho at an orphanage, complimenting Kakucho's scar. When he learns Kakucho is making a grave for his parents, Izana destroys it, telling Kakucho to forget those who died, as his life is now worthless. Kakucho attributes Izana to giving his life a purpose as his servant. Aside from his devotion to Izana, Kakucho and Izana are also childhood friends and playmates; Kakucho recalls he and Izana playing in the snow while planning Tenjiku.

Because of his undying loyalty to Izana, Kakucho also cares for Izana, wanting to stop Kisaki from warping and manipulating Izana through his underhanded tactics. He makes clear his oppositions, such as asking Izana to reconsider the plan to murder Emma Sano, as well as slapping a gun out of Izana's hands. Kakucho always sees himself as inferior to Izana, questioning why Izana would sacrifice himself, a king, to protect him, a mere servant. After Izana dies, Kakucho cries in grief, saying that he will join him in death soon. When Kakucho finds himself alive, he expresses guilt in being a survivor, while people such as his parents and Izana die. To gain closure after Izana's death, Kakucho visits their childhood orphanage and creates a makeshift grave for Izana, telling him to rest well.
