“Me, join your force? Sorry, but I don't intend on working with anyone other than Yukikaze.”
—Rinko
Rinko Akiyama (秋山 凜子 Akiyama Rinko?) is one of the main characters of Kaiju of Retribution Tatsura and Tatsura vs. Hellbourne. She is the elder sister of Tatsurou Akiyama, the protagonist of Neo-Sengoku Trilogy.

Appearance Edit

Rinko is a very beautiful woman with a very curvaceous and erotic body coupled with a huge pair of breasts. She has very long blue hair that reaches even to the back of her knees and magenta eyes. Her Taimanin suit is a purple bodysuit with gold accents on the clothes' edges, golden "nipples", an opening on the middle of her bust, silver armored gauntlets and leggings.

Personality Edit

Rinko is described as an honorable, serious, and diligent individual. Like with most Taimanin, Rinko possesses a strong sense of justice and an intense hatred toward evil men like the slave trader Zokuto, the corrupt politician Yazaki, and the brothel operator Real. Compare to her best friend Yukikaze, Rinko is more capable of keeping a collected composure in extreme situations and is better at hiding her emotions. Her calm personality sometimes falters when her large breasts are the subject to ridicule by her enemies. Despite the mature image that she projects, Rinko can be rather naive due to her lack of experience, a trait she shares with Yukikaze. Her naivete is best demonstrated during her mission to infiltrate Yomihara when she is tricked by Zokuto into letting herself be sold into sex slavery for real instead of simply disguising herself as a prostitute like originally planned. Even after realizing that she had been tricked, Rinko still decides to continue her search for Shiranui, even though most Taimanin would have aborted the mission after the mishap. Due to her strong desire to rescue Shiranui and her stubbornness, Rinko is willing to go so far as to give false reports to her superiors to keep the dangerous mission ongoing.

Rinko's biggest defining trait is her loyalty to who she considers the four most important people in her life: her brother Tatsurou, best friend Yukikaze, honorary aunt, Shiranui and her eventual boyfriend, Zark Albatrosa. She is willing to go to great length for their sake, and is willing to suffer all kind demeaning acts during her time as sex slave for Under Eden if it means saving her best friend's mother, or work as Ryuuji Kuroi's maid to fulfill that mission or at the very least spare Zark.

Evil Universe Counterpart Edit

In the Evil Universe's Timeline, where the Matoi Mission was not canceled early and Rinko and Yukikaze stay at Under Eden as opposed to being extracted by Asagi and Sakura, Rinko's personality changed significantly as a result of her experiences at the brothel. After having her body modified and her traumatic experience inside of Under Eden's flesh vessel, Rinko became more reserved and submissive. After spending months of being a slave prostitute for Under Eden, Rinko seemly returned to her old self to some degree, but this turns out to be just an act. In truth, due to Under Eden's conditioning, brainwashing, and her daily life as a sex slave, Rinko ultimately gives into the her carnal desires. She eventually became a masochistic nymphomaniac that finds pleasure in being a sex slave. Rinko also develops Stockholm syndrome and falls madly in love with Real, Under Eden's owner. At this point, Rinko is stated to be "Real's personal bitch", and, in his words, is now "a woman that will throw everything away for his sake". Rinko is willing to betray Tatsurou and Yukikaze for Real, claiming that she is unable to go against his orders. This counterpart of Rinko acts more spiteful and cold towards Tatsurou. Although she does show some regrets for her actions, such as apologizing and asking for brother's forgiveness as she is attacking him. She has stated that Tatsurou is free to scorn her, but he would never truly understand her feeling as a woman.

Relationships Edit

Tatsurou Akiyama Edit

Tatsurou is Rinko's younger brother. Rinko loves her brother dearly and openly shows affection towards him. A few characters have called Rinko a "brocon" due to her adoration for her brother, which Rinko would deny. She occasionally like to playfully tease Tatasurou. Rinko often encourage Tatsurou to have more confidence in himself as a Taimanin and in his relationship with Yukikaze. Rinko fully supports Tatsurou relationship with Yukikaze and often tells him to act more manly around his girlfriend.

Tatsurou also loves his sister greatly. However, Tatsurou has admit a big contributor to his self-doubt comes from his own abilities being constantly compared to Rinko's. Tatsurou does not believe that he will ever be able to surpass his sister in terms of ninjutsu. He sees himself as unworthy to be the next head of the Akiyama household (a position that is normally given to the first born son of the Akiyama family), and considers letting his sister take over the position as its first matriarch. Despite this, Rinko believes in her brother's abilities and has become his personal kendo instructor in help him improve his swordsmanship.

Rinko's Evil Universe counterpart, on the other hand, has a very hostile relationship with her brother. Due to the brainwashing done to Rinko at Under Eden, Rinko becomes more spiteful and cold towards her brother. Rinko deceives Tatsurou to keep the Matoi Mission ongoing and sets up her brother for a downfall. She betrayed the Taimanin by protecting Muneichi, under Real's orders, from Tatsurou during his attempt to kill the evil politician in order to save Yukikaze. Rinko does display some regret for her actions, apologizing to her brother as she is attacking him and has stated that he is free to scorn her. But soon after Rinko coldly tells Tatsurou to leave and that he would never understand her feeling as a woman. Rinko and a brainwashed Shiranui then defeats Tatsurou. They have him removed from Under Eden. Tatsurou afterwards disown his sister for her betray. During the next year, Tatsurou would watch videos of Rinko and Yukikaze on Under Eden's website while wasting his life way. Eventually, Yukimaru Katsuki convinces Tatsurou to go on time traveling adventure with him to save Rinko and Yukikaze from their fates, showing that despite everything that Evil Universe's version of Rinko has done to him, Tatsurou still cares about his sister.

Yukikaze Mizuki Edit

Rinko and Yukikaze

Rinko and Yukikaze displaying their sisterly bond.

Yukikaze is Rinko's best friend from childhood. Rinko regards Yukikaze as the little sister that she always wanted and loves her as such. Yukikaze in turn views Rinko as an older sister. Yukikaze was Rinko's first kiss outside of family. When Rinko was a little girl, she caught Yukikaze and Tatsurou sharing their first kiss. Feeling left out, Rinko demands that her best friend and brother also give her a kiss as well. However, since the two were only little kids that didn't fully understand the significance of kissing, neither Yukikaze or Rinko considered the kiss they shared as a "true kiss". Rinko and Yukikaze continued to remain close friend even after they reach adulthood. They trained together at Gosha Academy. The two women were able to make a reputation for themselves relatively early in their careers as Taimanin, and prove to be a formidable team. Rinko is willing to do anything for Yukikaze's sake. She volunteered for the Matoi Mission to find Shiranui mainly out of her desire to help Yukikaze reunite with her mother. Even after the mission was cancel early after the realization that it was set up, Rinko continue to help Yukikaze search for Shirnaui. Rinko also fully supports Yukikaze's relationship with her brother Tatsurou, and believes that their "first time" should be done with each other. When Rinko and Yukikaze were sent out on the Matoi Mission, Rinko continuously reassures Yukikaze that no matter what happen, Tatsurou would always love her.

In the Evil Universe's timeline, Rinko still seems to have some affection for Yukikaze. However, due to her brainwashed state caused by Real, Rinko was conditioned to believe that Yukikaze would only be truly happy if she accepts her role as Under Eden's slave prostitute. As a result, this version of Rinko will do anything to keep Yukikaze in Real's and Yazaki's grasps.

Shiranui Mizuki Edit

Rinko views Shiranui as an honorary aunt and addresses her as "Auntie Shiranui". Before her disappearance, Shiranui treated Rinko like she was a member of her family, not just as surrogate niece, but sometimes like a second daughter. It is due to their close relationship that Rinko is almost just as determined as Yukikaze to find Shiranui.

In the Evil Universe, the brainwashed Rinko and Shiranui got along well with each other. Shiranui was able to convince Rinko to help her in keeping Yukikaze at Under Eden to complete her brainwashing, so that the three of them can be "happy" together. The two former Taimanin would then work together to defeat Tatsurou during his attempt to save Yukikaze. In an alternate timeline, where the Matoi mission continued but Rinko does not develop Stockholm syndrome for Real, Rinko tries to fight Shiranui to protect Yukikaze and Tatsurou. Although Rinko is hesitant about it, she does use lethal force against Shirnaui. Despite her best efforts, Rinko was defeated by Shirnaui in that timeline.

Real Edit

Rinko and Real

Rinko in Real's thralldom

Rinko despised Real even before official meeting him due to his occupation as an owner to a brothel that kidnaps women and forces them to prostitute themselves. Her hatred for him only grew after meeting Real in person and seeing what a sadistic monster he is. Although Rinko is able to keep a level-head when interacting with Real, she makes her dislike for him known. Rinko has contemplated killing Real should the opportunity presents itself. Real wants to get revenge on Rinko for what she and Yukikaze did to his brother, Yazaki, during the Skyscraper mission. Real sees Rinko as lust object and desires to sexual torture and humiliate the Taimanin. While Rinko has the slave mark placed on her, he finds Rinko's small act of defiance towards him to be amusing, knowing she can't but up greater resistance against him. Due to Real's physical attraction toward Rinko and her spunky attitude toward him, Real plan to dominate Rinko until she becomes "his woman". Although Real wants to keep Rinko in his thralldom, he is pragmatic enough to not put his own life in danger to keep her enslaved. When Asagi and Sakura coerced Real into releasing Rinko and Yukikaze in exchange for his life, he reluctantly agrees, stating that he does not want to loss his life for two "idiots".

In the Evil Universe's timeline, Rinko relationship with Real drastically changed the longer she stayed at Under Eden. In this timeline, Real was to one who took Rinko's virginity. For the next few months after Rinko was coerced to be a slave prostitute, Real frequently forced Rinko have sex with him. Even after Rinko completed her daily "training", Real compelled Rinko to have further intercourse with him as "his lover" or else he would punish Yukikaze if she refused. At some point during Rinko's training, Real had Rinko put inside of the "flesh vessel" for 2 weeks. The experience left Rinko traumatized. Real forced Rinko to swear to never go against his orders or he will have placed back into the flesh vessel, which the terrified Rinko complies to. After the incident Rinko stopped showing acts of defiance towards Real.

During the next several months, Rinko would continue her daily life as a slave prostitute. Rinko and Real regularly engaged in sexual intercourse with each other. Due to the mental conditioning and brainwashing done to Rinko, she eventually started enjoying position as a slave prostitute for Under Eden. Rinko develops Stockholm syndrome, falls madly in love with Real, and accepts him as her master. At this point, Real has become the most important person to her. She would frequently fawn over Real when they are alone together, claiming that she needs nobody else but him. Rinko has states that she is unable to go against Real's orders and sees them as "absolute". Under Real's order, Rinko betrayed the Taimanin, including her brother and best friend. In Real's own word, Rinko has truly become a "a woman that will throw everything away for his sake". Afterwards, the Evil Universe counterpart of Rinko continue to serve Real as both his enforcer and his prized slave prostitute at his brothel.

Muneichi Yazaki Edit

Yukikaze holds Yazaki at gunpoint

Rinko and Yukikaze's first meeting with Yazaki.

Rinko absolutely loathes Yazaki, although she is better at hiding her disgust than Yukikaze. During the Skyscraper mission, Rinko and Yukikaze stop a deal that Yazaki was trying to make with a group of demons. The Taimanin killed off all the demons that were present before briefly interrogating the corrupt politician. The Taimanin were ordered to let Yazaki live due to his position as the Chief Secretary of the ruling party in Japan. Despite the order, Yukikaze insistence on killing Yazaki. Rinko explains Yazaki will likely be marked for assassination in the near future if he continue to make deals with demons. Yazaki then goes on to insult the Taimanin during the interrogation, upsetting Yukikaze enough to kick him jaw and knocking him out, an act that Rinko overlooks. Ever since that mission, Yazaki has come to despise the two women, although most of his hatred was directed at Yukikaze for her more hostile attitude towards him and for the damage she cased to his face. Yazaki latter set up the Matoi Mission as a means to getting revenge on them.

In the Evil Universe, Yazaki was one of Rinko's best customers after she became the number one slave prostitute in Under Eden. The two apparently made many videos together for Under Eden's website while Yazaki used the stage name of "Mr. X".

Zark Albatrosa Edit

Wataru Akiyama Edit

Abilities Edit

  • Chi Sensitivity - Born from the Magi human species, her body is reactive to mana and is able to cast supernatural powers because of this.
  • Master Swordsmanship - While she was struggling to engage melee combat at her enemies in her debut appearance, Rinko learned to get better at her abilities in managing sword combat. Eventually, she became so good and skilled that she can be able to decapitate any enemy near her without problem, earning her nickname "Demon Decapitation Taimanin". She masters her own signature sword fighting style, the Lost Sword Style (逸刀流 Ittōryū?)
  • Supernatural Speed - As a Taimanin, she is capable of swiftly cutting down multiple demons without them noticing it.
  • Ninja Arts - Art of Sky Escape (忍法・空遁の術 Ninpō - Kūton no Jutsu?) - A space jump unusual power system of ninja art. Making her five senses jump a distance of approximately 1 kilometer and perceiving the opposite side of walls or the scenery of distant locations using the "Senses Jump Method" and making herself and surrounding people or things jump using the "Space Jump Method" are ways she can use her jutsu. This ability requires the usage of her mana/chi, which would explain why her signature jutsu is similar to a magic spell from a sorcerer or a Justice Alliance member. However, the "Space Jump Method" brings about a temporary, yet violent fatigue upon the practitioner.
  • Super Robot Piloting - She is also familiar with the functions, mechanics and ways of a piloting a gigantic robot. That way, in Tatsura vs. Hellbourne, she is able to control the Super Robot Saigord-Golem when its former pilot was killed. She was at first unfamiliar at piloting the mecha, but she learned how to properly fight with it. Therefore, even when she doesn't have a kaiju form to fight giant enemies with, she makes up for it by piloting a giant robot. In Kaiju World War: Part 1, when Golem was destroyed, Rinko was then given the upgraded model, Saigord-Zetsu, to control.
    • Robot Linking - Using her chi, she and Zark can telepathically link together Saigord-Zetsu and Armed Zephyrus' capabilities with each other, allowing the two to combined into the ultimate super robot Dyna-Saigord-Zetsu.

Weapons Edit

  • Ishikiri Kanemitsu: A 74 centimeter long katana. The sword is the ancestral blade of the Akiyama family. The previous owner of the blade was Rinko's father, before he passed it down to his daughter. The blade is very sharp and can cut through the flesh of demons whose skin can withstand bullets.
