The Hito Hito no Mi, Model: Onyudo is a Mythical Zoan-type Devil Fruit that allows its user to transform into an onyudo, a large monk yokai, at will.[3] It was eaten by Onimaru.
An "ōnyūdō" (大入道?) is a type of Japanese yōkai that takes the form of a gigantic monk.
Strengths and Weaknesses[]
This fruit's ability is to transform into an onyudo: a mythical, human-like yokai that takes the form of a giant monk;[3][2][4] Onimaru, in particular, stands at over four meters tall.[3] This fruit being of the Hito Hito no Mi series, its transformation grants a nonhuman user human intelligence and the ability to speak the human language.[2]
So far, no weakness of this Devil Fruit power is known beside the standard Devil Fruit weaknesses.
Usage[]
Gyukimaru turning back into Onimaru.
Onimaru is able to transform from his komagitsune self into a large, naginata-wielding onyudo known as Gyukimaru. In his Gyukimaru form, he possesses a human intellect that comes with the ability to speak[2] and a presumably extended lifespan, given the fox's age of 69 years.[3]
Befitting his size, Gyukimaru has enormous strength in his onyudo form, as he could match up to Roronoa Zoro's physical power for some time. He also has great speed, able to match Zoro's agility in their first match, deftly wielding his naginata against Zoro's two swords.[2][5] However, in their second bout he was overwhelmed by Zoro without much effort on the latter's part, implying that Onimaru may have had an advantage in the first match due to catching the opposing swordsman off-guard.[6]
Onimaru has yet to display any "mythical" abilities outside of his transformation.
Trivia[]
Certain versions of the ōnyūdō myth are known to involve shapeshifting kitsune disguised as the former creature, reflecting Onimaru's own usage of the fruit.
Like the Hito Hito no Mi, this fruit grants the ability of speech, making it the second fruit to do so.
When transforming, Onimaru does so in a puff of smoke akin to those seen from the usage of certain ninjutsu.
