OVA
Description
Takeru Ōyama enters Tenbi Academy, a newly co-ed institution formerly for girls, where students wield supernatural Maken weapons fueled by spiritual Element energy. Initially motivated by romantic pursuits, he is swiftly drawn into the academy's combat-centric world. He shares a residence with childhood friend Haruko Amaya, self-proclaimed fiancée Inaho Kushiya, and Kodama Himegami, who views him as an enemy after an accidental first kiss activates a mystical mark on his chest.

Son of Takeshi Ōyama and Atsuma Ōyama, Takeru harbors deep resentment towards his father and uncle Tesshin Kushiya, blaming them for failing to prevent his mother Atsuma's death from illness following a lost duel during his childhood. This trauma fuels his "white knight syndrome," an absolute refusal to fight women or witness them in combat, compelling him to intervene in female duels.

Takeru wields two core abilities. Blood Pointer absorbs emotional energy through touch, converting it into Element for healing or empowerment at the cost of shortening his lifespan. Overblow, his official Maken, disrupts opponents' weapons by overloading them with Element; controlled adversaries instead gain amplified power. These latent abilities first emerge under stress, often when protecting allies.

A pivotal confrontation occurs during the Summer Training Camp arc within a cave. Takeru battles Tesshin, accusing him of his mother's death. The fight forces Takeru to acknowledge his refusal to fight women as emotional weakness. After absorbing Tesshin's Element to heal a self-inflicted wound, he accepts that neither Tesshin nor his father caused Atsuma's illness, resolving his long-standing trauma and altering his combat philosophy.

Takeru navigates complex relationships. He trains with Haruko at his family dojo; she denies romantic feelings despite displays of jealousy. Inaho reveals a forgotten childhood promise where Takeru vowed to protect her, suppressed due to his head trauma. Kodama discovers Takeru is a distant relative through shared ancestry with Yabiko Himegami, easing her initial hostility. His perverted tendencies spark frequent comedic clashes, though he shows restraint in vulnerable situations, such as when stranded with teacher Aki Nijou.

Physically, Takeru evolves from frequently broken glasses—eventually discarded—to greater athleticism. His brown hair and green eyes remain constant, but his physique strengthens significantly under Minori Rokujou's regimen using 100kg kudatama weights, boosting his speed and combat reflexes.

In the final arcs, Takeru learns he descends from Yabiko Himegami, explaining his resemblance and Blood Pointer inheritance. He opposes the Yamato family, specifically the ancient spirit Takeru Yamato possessing modern descendants. During the climactic battle, Takeru expends all his Element to defeat Yamato, shattering his Maken and permanently losing his powers. This forces his transfer from Tenbi Academy, though he maintains connections with his friends.
