## Yaiba[[edit](/wiki/index.php?title=Takeshi_Onimaru&action=edit&section=1 "Edit section: Yaiba")]
Originally a very serious person, Onimaru could not get along with [Yaiba](/wiki/Yaiba_Kurogane "Yaiba Kurogane") at all and the two quickly became rivals. In order to defeat his hated enemy, Onimaru began training with his family's sacred sword, the Fuujin-ken, until he was possessed by it and turned into an actual demon (the character for *oni* in his name means *demon*). He soon took over all of Japan, traveling in a flying castle. His minions include [Kumo-Otoko](/wiki/Kumo-Otoko "Kumo-Otoko") and the [Hakki](/wiki/index.php?title=Hakki&action=edit&redlink=1 "Hakki (page does not exist)"), the [Kuroki](/wiki/index.php?title=Kuroki&action=edit&redlink=1 "Kuroki (page does not exist)"), the [Shiteno](/wiki/index.php?title=Shiteno&action=edit&redlink=1 "Shiteno (page does not exist)"), and many completely black oni. Eventually, he switches from the Fuujin-ken to the Maou-ken.
After Yaiba cuts off his horns, he returns to being a normal human. At first he viewed Yaiba as a nuisance, but after training with Yaiba's father [Kenjuro](/wiki/Kenjuro_Kurogane "Kenjuro Kurogane"), he returns for the final story and now acknowledges Yaiba as a friendly rival. During the Oda Nobunaga Tournament, he has a dove as a pet.
## Appearance[[edit](/wiki/index.php?title=Takeshi_Onimaru&action=edit&section=2 "Edit section: Appearance")]
Onimaru is a tall man with a bald head, a serious expression, and a thin body frame. After turning into an Oni, he's become bulkier and taller, with a much more muscular body and small horns protruding from his forehead. As a student, he wore the typical black uniform. In his demon form, Onimaru dons a fearsome elaborate armor with the breastplate shaped like a grinning skull, spiked shoulder pads and decorated greaves and bracers trimmed with black fur. He also wears a red cloak and occasionally a black helmet shaped like a dragon's head. He also has a jetpack in the back of the armor. During the Oda Nobunaga tournament he wears a black kimono. He also has a weird dot in the middle of his forehead.
## Personality[[edit](/wiki/index.php?title=Takeshi_Onimaru&action=edit&section=3 "Edit section: Personality")]
When he was possessed by the Fuujin-ken, Onimaru turned into an Oni and wanted to take over Japan, and eventually, the world. He became cruel and wanted to kill Yaiba and his friends. However, when Kaguya came to take over Earth, he and Yaiba teamed up to stop her. After Kaguya was defeated, Onimaru said he still planned to beat Yaiba and left. In their final battle, when Yaiba cut off his horns, he returned to his old self and saw Yaiba as a good rival. After that, Yaiba's father, Kenjuro, taught Onimaru kendo.
In Detective Conan, he appears more polite than in Yaiba. He apologized to Ran for bumping into his armor, though he didn't help her get up. He also talked politely with coach and even laughed a little.
## Abilities[[edit](/wiki/index.php?title=Takeshi_Onimaru&action=edit&section=4 "Edit section: Abilities")]
Before being possessed by the Fuujin-ken, Onimaru was skilled in kendo. In the manga, he was able to defeat the captain of the kendo club with one strike. After he was possessed, he used magical wind powers to fight and later the Demon King Sword. After Yaiba cut off his horns, Onimaru returned to his original self, and Yaiba's father taught him kendo.

Ran and Onimaru.
In contrast to his prior demonic characterization, in the manga canon Takeshi Onimaru appears as an honorable, polite, and serious young man, albeit frightfully massive and skilled at kendo. He apologizes to [Ran](/wiki/Ran_Mouri "Ran Mouri") when she runs headlong into his hard chest protector and winds up on the floor. He does not help her up though, and seems more concerned with refusing an honorary citizenship, which [Momiji](/wiki/Momiji_Ooka "Momiji Ooka") set up for him so he would leave the tournament so [Heiji](/wiki/Heiji_Hattori "Heiji Hattori") could win, he feels he does not deserve due to his perceived lack of worthiness. Overall, his character appears to more purely embody a Makoto-type samurai mentality who likes fighting strong opponents. As he discusses the citizenship with the manager, he seems polite and even gives a small laugh as both leave the hall.
