OVA
Description
Aya Iseshima is a second-year high school student whose generally cheerful demeanor is punctuated by periods of angsty moodiness. Her life centers on her close friendship with Natsume Honma and a romantic interest in Natsume's brother, Haruki Honma—a friendship masking a complex conspiracy targeting her family, initially unbeknownst to her.
She possesses extensive martial arts training inherited from her mother, Suzuko Iseshima, making her a capable and devastating fighter. This skill erupts most intensely in combat, where she enters a berserk state of uncontrollable rage, leading to brutal outcomes. Prior to the main events, she defeated an entire school of bullies single-handedly, an act that inadvertently isolated her through the fear it instilled.
Aya enters the Martial Hearts tournament after encountering Miko Kazuki, a shrine maiden fighting for the wish to make friends. When Miko withdraws and disappears following their new friendship, a text message enrolls Aya as Miko's replacement. Her primary motivation for participating is to locate the missing Miko, reflecting her loyalty and sense of responsibility.
Throughout the tournament, Aya faces opponents from diverse professions, including her chemistry teacher Azusa Suma and flight attendant Rei Kakizaki. Her fighting style relies purely on instinct and raw power, often resulting in severe damage to adversaries. A pivotal fight against the psychic Getsurei Ryu triggers Aya's most extreme berserk episode under psychological probing, culminating in a lethal beatdown.
The final confrontation reveals a devastating betrayal: Natsume, Haruki, and Miko conspired to ensnare Aya in the tournament as revenge against her parents. Aya's father, Shigeyuki Iseshima, created the original tournament, and her mother Suzuko won it, forcing Natsume and Miko's mothers (Kumi and Yumi Kazuki) into sexual slavery. The trio intended Aya to suffer mind-controlled enslavement as punishment, a revelation that shatters her psychologically, compounded by witnessing the brainwashed state of previous losers.
Suzuko intervenes during Aya's captivity, killing Haruki, Natsume, and Miko before helping Aya escape a burning building. Suzuko remains behind, her fate ambiguous. Physically injured and mentally scarred, Aya limps away alone. The series concludes with her approaching Kumi Honma's residence, implying her intent to confront Kumi, the mastermind behind the revenge plot, to end the cycle of vengeance.
