Takeru Ooyama

Takeru Ooyama is a member of the Student Council Security Division, a freshman student at Tenbi Academy, and the central protagonist of the Maken-Ki series.

Takeru originally enters Tenbi Academy without any knowledge of the school, other than that the school had changed from all-girls to co-ed. Before moving to Tenbi, he was at an all-boys school.

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 but his exact rank is unknown.

Takeru is best friends with Davis Motomiya. He is also a member and co-founder of the Loser's Club.

Appearance
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.

In the AWA fics, 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.

Personality
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.

In the AWA fics, 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.

Abilities
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.

In the AWa fics, Takeru is yet to demonstrate his new strength and skills.
