Takeru Ooyama is the main protagonist from the Maken-Ki anime and manga.

Takeru recently enrolled at the Tenbi Academy with his childhood friend, Haruko Amaya. Since he's new at the academy, he's struggling to adjust to how things work, such as their duelling system, where his predisposition to protect girls rubs the other students the wrong way, when he interferes. Which might be easier for them to forgive, if he also wasn't a pervert. 

In the AWA fics, Takeru is a student at the AWA Academy and is a part of Class 23. Takeru is also part of the AWA Rookie 20 and is ranked #4. Takeru is best friends with Davis Motomiya. He is also a member and co-founder of the Loser's Club. 

In the XP4 fics, Takeru debuted in the XP4 Heroes Coalition - Mission Chronicles.


Takeru is a teenager with brown hair that is shaved close on the sides and forms a crown in the back. He originally wore glasses, and presumably still needs them, but has stopped wearing them as "they kept getting broken too often". His usual attire is the Tenbi Academy male student uniform which consists of a white shirt, green tie, blue pants, and black shoes.

AWA Fanfics

Takeru's body was slightly rounder. He usually wears a black sleeveless t-shirt with the words 'Kill Ooyama Kill' written at the back and front, black knee-length athletic shorts, black socks and black boots.


Takeru is a helpful and kind person, but has a perverted mind. Although he doesn't really mean to do these perverted things on purpose to Haruko he still gets beat upon her. He never thinks before he acts, as described by Haruko. He never wanted to see women fight, or to fight women, when his mother Atsuma died after she lost a duel; and considers his father the one responsible for her death, despite her dying from a disease.

After encountering Tesshin during the Summer Camp arc, Takeru has since changed his opinion of fighting women, recognising it as his own weakness and refusal to face his past. He has also apparently forgiven Tesshin and his father, realising that they were not at fault for Atsuma's death.

AWA Fanfics

Takeru's character was drastically changes a bit despite remaining the same as canon. Takeru pretends to be more benign about it but the sadism is undeniable once he gets in a fight. And like Davis, he’s shown himself to be very, very good at punching people’s buttons in ways that let him take brutal advantage of them. As of lately, Takeru has become a lot more sadistic and brutal.

XP4 Fanfic

Takeru is a member of the Heroes Coalitions and is part of the Maken-Ki. He also attends the Vanguard Academy as a student.

XP4 Heroes Coalition - Mission Chronicles

In Chapter 18, Takeru alongside the rest of Maken-Ki are seen chasing a criminal named Peeper Pete around the academy and when they cornered him, Pete unexepectedly taken them all down and were about to abduct them using the Dark Followers. Fortunately for them, the Dream Team arrives and save them and after that, Takeru and the others thanked the team with him & Kengo Usui making lewd remarks on Medaka Kurokami's figure which earned them a glare from the boys. Medaka then suggested that they had a discussion in their headmaster's office.

In Chapter 19, Takeru is present in Tenbi Academy's headmaster office where the Dream Team explains things to them. He along with everyone agreed to form an alliance with the Heroes Coalitions and later heard Peeper Pete warning everyone that his fellow followers will do everything to awakened their goddess, Lady Adele before getting knocked-out by Tenten.

XP4 Heroes Coalition - Neo-City Diaries

In Chapter 65, Takeru alongside the rest of Maken-Ki are seen inside the joint room of the Disciplinary Committee and the Safety Patrol having a conversation with Kiyotaka Ishimaru, Cornelius Fillmore and Ingrid Third.

In Chapter 66, Takeru is present during Vegeta's serenade in the school grounds of the Vanguard Academy.


Overblow - Takeru's maken causes his opponent's maken to gain incredible power and overflow with element causing it to go out of control and force the user to be unable to use it. The downside to this maken is if his opponent is able to contain the overflow of element or has perfect control over his/her maken, it would only provide his opponent greater power or even make the maken evolve into something greater. His attack with this maken is Drive Duo, and Blood Duo. However, this is described as a side effect by Gen, and the true power of Overblow lies in the ability to erase dark/evil element.

Blood Pointer (Buraddo Pointaa) - Takeru's hidden ability, this ability allows the user to drain elements from their environment through their mouth, increasing their strength and healing them if necessary. It weakens the people who the user drained the element from. It is unknown how easily it can interrupted; the only person to interrupt an berserk Blood Pointer was Kengo Usui, who had the Element Canceller ability. As Element is needed for life, as well as attacks and manifesting maken, it is quite possible that a berserk Blood Pointer would be unstoppable without a long-range attack or a user with a near-infinite amount of Element.

Fist Blade - A technique used by Takeru after using his Blood Pointer ability. This element is built up in his hand and fired at the enemy as a huge blade of element.

Absolute Fist - a charged punch delivered while Takeru is moving at high speed.
