Black Clover Wiki

Daizaemon Ōoka 「大岡大左衛門 Ōoka Daizaemon」 is one of the Ryuzen Seven of the Hino Country.[2]


Daizaemon is a large man with a wide build and shaved head.

Daizaemon wears a dark-colored kimono over a light-colored shirt and cinched by a rope belt. Around his neck is a set of large prayer beads. He also wears a pair of loose, light-colored pants that are strapped with socks.


Daizaemon is a boisterous man, often shouting and loudly laughing.[3] Despite his monk-like appearance, he is given to having lecherous thoughts.[4]


Daizaemon, Jozou Hanegatsuji, and Komari Imari meet up with Ryuya Ryudo and Ichika Yami to train Asta. The three quickly beat up the foreigner, knocking him unconscious. Daizaemon loudly welcomes Asta to the Hino Country, while Humito Mikuriya heals the foreigner. When Humito suggests that Komari's fashion sense might spread, Daizaemon has perverted thoughts about her outfit, which creeps out Komari. Ryuya thanks the three for coming and has them continue training with Asta.[5]

Later that night, when three Paladins arrive in the country, Ryuya sends Daizaemon and four of the other Ryuzen Seven members to evacuate Goshu in preparation to fight the Paladins and the awakened five-headed dragon.[6] The Ryuzen Seven gather on the rooftop of the regional lord's palace[7] and are approached by Lily Aquaria.[8] When the dragon attacks, Daizaemon uses Giant King of Wisdom and Zetten to punch one of the heads, smashing it apart. At the same time, the other Ryuzen Seven members deal with the other heads.[9] Lily and Heath Graice then unleash a combined spell that strikes down all five warriors, heavily injuring them.[10] Despite their injuries, Daizaemon, Jozou, and Komari refuse to give up, preparing to continue fighting, but are taken aback as the five-headed dragon restores its heads.[11]

Asta decapitates five-headed dragon

With the Ryuzen Seven's help, Asta decapitates the dragon.

After Asta's Anti Magic also fails to permanently injure the dragon, the Ryuzen Seven still refuse to give up, and Ryuya and Fujio Tenmanyashiki encourage and bolster them from the palace rooftop.[12] While Ryuya uses his Tengentsu to analyze the dragon, Fujio reinvigorates the other Ryuzen Seven and communicates Ryuya's commands to them. Daizaemon creates another Giant King of Wisdom and grapples with the same dragon's head, forcing it into position. Asta then severs all five heads simultaneously, killing the dragon.[13]
