  • Aya Iseshima (伊勢島 綾, Iseshima Aya) is in her second year in high school. In the OVA, she is a generally cheerful and pleasant girl who has a crush on her best friend's brother, but has angsty moods where she mopes and whines.[4] She is pulled into the tournament when Miko drops out and mysteriously disappears. She is a capable fighter, having learned fighting techniques from her mother. When Aya fights, she can turn into a maddening rage, resulting in devastating damage. She is voiced by Kaori Nazuka in the Japanese version, and by Anita Neukar in the English dub.[5]
  • Natsume Honma (本間 棗, Honma Natsume) is Aya's best friend. In the OVA, Natsume's supportiveness for Aya is an act—in the final episode, she betrays Aya and reveals that she, her brother, and Miko have all conspired to exact revenge on Aya and her family. Natsume's mother is Kumi, the sister of Yumi Kazuki, Miko's mother. Natsume is voiced by Satomi Akesaka in the Japanese version, and by Cherami Leigh in the English dub.
  • Miko Kazuki (香月 美子, Kazuki Miko) is a shrine maiden. In the OVA, she initially appears in a fight against Rei, a young woman dressed as a flight attendant. After Aya defeats Rei, Miko explains that she is participating in a tournament that grants any wish upon victory. Seeing that her wish of making friends was fulfilled by Aya and Natsume, she tries to withdraw from the tournament. However, Miko mysteriously disappears later on. Miko later appears at the end of the series as a vengeance-filled enemy of Aya as her mother, Yumi Kazuki, and her aunt, Kumi, were involved in a previous tournament with Aya's mother (Suzuko) ruining their lives. Miko reveals that her father was Shigeyuki Iseshima, who is Aya's father. Even though Aya believed Shigeyuki died in a car accident, in actuality, he stabbed Yumi Kazuki on Miko's fourth birthday and was killed by Kumi the same day. Miko had been looking for Suzuko and her daughter her entire life—she finally achieved her goal upon meeting her cousins, Haruki (Natsume's brother) and Natsume. Their vengeful plan was formed after Miko met Natsume. Miko is voiced by Ai Nonaka in the Japanese version, and by Alexis Tipton in the English dub.


  • Haruki Honma (本間 治基, Honma Haruki)
    • Natsume's brother, whom Aya has a crush on. It is revealed in the final episode that Haruki is in a relationship with Miko all along. Tatsuhisa Suzuki voices him in the Japanese version and Ian Sinclair voices him in the English dub.
  • Suzuko Iseshima (伊勢島 涼子, Iseshima Suzuko)
    • Aya's mother. She won the previous tournament, dooming Kumi and Yumi Kazuki to sexual slavery. In the final episode, she infiltrates the hideout of Miko, Haruki, and Natsume. Suzuko sets the area on fire and confronts the three perpetrators to save Aya's life. After informing the trio of what their grandfathers did she snaps the necks of Haruki, Miko, and Natsume when they tried to attack her. Suzuko then bandages Aya's wounds, apologizes to her, and helps her flee the building. Afterwards, Suzuko stays behind in the burning building and checks Aya's phone—she finds out that the pieces of the Martial Heart have not been completed. The burning building then collapses, with Suzuko's fate unknown. Naoko Matsui voices her in the Japanese version and Shelley Calene-Black voices her in the English dub.


For the Zettai Shougeki: Platonic Heart video game, the following women were listed in the lineup on the official site as competitors along with the main three girls.[6]

  • Azusa Suma (須磨 梓, Suma Azusa) is Aya's chemistry teacher. Azusa attacks by calling out a chemical formula and then uses a combination of punches and kicks based on it.[7] Although Azusa criticizes Aya for not studying, she has reservations for fighting her. Azusa's motivation for fighting in the tournament is to find her missing father. Azusa is enslaved by Miko after losing to Aya, and Miko uses her as the first "example" of the fate that befalls the losers of the tournament; Aya tries to make her return to sanity, but Azusa is so far gone that she cannot. She is voiced by Luci Christian in the English dub.
  • Rei Kakizaki (柿崎 怜, Kakizaki Rei) is a flight attendant. In the OVA she had worked since high school to care for her younger brother, since her parents were no longer alive. Her brother fell ill with an incurable disease and she wanted to get money through the tournament to give him adequate medical treatment. By the end of the series, Rei's brother had died; having been tortured to insanity, Miko points out that it is impossible for Rei to know that her brother is dead. Rei's weapons are a handbag with blades and a spiked scarf.[8] Voiced by: Colleen Clinkenbeard (English)

  • Kumi Honma (née Kazuki)
    • The mother of Natsume and Haruki. Several years ago, Kumi and her sister Yumi Kazuki were sold into sexual slavery to a man overseas after she lost the Martial Heart tournament to Suzuko Iseshima. Her vocal cords were destroyed to prevent her from screaming, and she has a noticeable scar on her neck. She escaped from her overseas master and used sign language and writing to tell her children what happened, then through the years she conditioned them to seek revenge for the horrors inflicted on her.. At the end, Suzuko reveals that Kumi had killed Shigeyuki Iseshima after he killed Yumi. Kumi also has a habit of stabbing pictures with Aya in it with a razor blade. In the final episode, she answers the door and is frightened at the sight of the outsider, strongly implied to be Aya. Kumi's actual fate left for open interpretation, but it's believed that Aya killed her either as punishment or to stop the whole cycle of revenge.

Aya faces her final opponent, Ryu Getsurei, a lady in red who says she is a clairvoyant who can see her heart. Getsurei tells Aya that the tournament is nothing more than a game, a trick by Miko. Angered, Aya defeats Getsurei, but not before the woman claims that Aya's heart has become "a sheet of darkness". Aya seems to snap and beats the woman to death, still hitting her after she has died. Miko appears and tells her that since Aya won she got her wish and Miko has returned. Miko takes Aya into a warehouse where all of her past opponents are being held. All of Aya's past opponents have gone insane and Miko says they are now "perfect women" that people would pay a lot for. While Miko is to explain why, a man who was pretending to be Haruki, who had used plastic surgery to disguise himself, and Izumi Hayakawa appear and finish explaining the reason. They worked for Miko and decided to betray her by choking her. She is saved by Natsume and the real Haruki: both are also in on the plan. They tell her that they were the ones who organized the entire Martial Hearts tournament as a way to take revenge on Aya's family. Before Aya was born her father, Shigeyuki Iseshima, and her mother, Suzuko Iseshima, set up the original Martial Hearts tournament and sold all the women who lost into slavery. Two of those women were sisters, one being Miko's mother Yumi Kazuki and the other being Natsume's mother Kumi. Yumi was given to Aya's father as a mistress and on her fourth birthday she witnessed him kill Yumi. Kumi had her throat slashed, effectively muting her, and was sold to a man overseas. Years later she was able to escape and tell her children her story. When Natsume and Miko met they realized that all their suffering came from Aya's family and chose to hold another tournament so they could destroy Aya. They shoot Aya twice but before they can further mutilate or kill her explosives go off throughout the building and it catches on fire. Suzuko appears, having set off the explosives, and tells everyone they are all caught in a web of vengeance. Aya's parents started the Martial Hearts tournament to seek revenge on Natsume and Miko's mothers, since their fathers were the evil men who killed their families, and now their daughters are caught in the web of revenge as well. Haruki and the girls attack her. Suzuko kills the three. She bandages up Aya and tells her she will atone for Aya's sins, staying in the burning building as a wounded Aya makes her escape. Later the audience sees Natsume's mother Kumi at home, carving up pictures of Aya, when the doorbell rings. When she answers it her eyes go wide in terror and she lets out a silent scream before the scene immediately cuts to black.

The OVA series received negative reviews from critics. Theron Martin of Anime News Network likens the series to Ikki Tousen where women fight each other with "clothes-shredding attacks" but wrote that Master of Martial Hearts has more extreme fan service such as exposed breasts. The plot "exists almost entirely to give excuses for staging cosplay-like battles."[1] Stig Høgset of THEM Anime Reviews found the show "a pretty simple and terrible story with a really awkward and dumb plot twist at the end, it's just impossible to recommend this show for anyone." He instead recommended other titles for those who are "up for the whole 'sexy girls chopsocky' thing." [10] Mike Ferreira of the Anime Herald wrote that it is "without a doubt, one of the most offensive, vile pieces of crap to pass through my DVD player. It makes Ikki Tousen look like The Gentleman’s Guide in comparison. There are absolutely no redeeming qualities to speak of, and everything just seems to go to extremes to repulse the viewer."[4] Bamboo Dong of Anime News Network praised Funimation for "cutting one of the funniest and most attention-grabbing trailers in recent anime history. Their coinage of 'Boobs, butts, and burgers' is genius," however, "Considering the terrible storyline, the complete lack of characterization, the lackluster animation, and the ear-splitting music, and the complete disregard for science, there is no redeeming feature of this show. Unless, of course, you want something to whack off to."[11] Chris Beveridge of found the story to be formulaic with awkward pacing, and leading to a spectacular train wreck of the final episode.[12]
