Akiyama Tatsuro

**Tatsuro** Akiyama (秋山 **達郎**) is a minor protagonist of Taimanin Yukikaze and Taimanin Yukikaze 2.

The Taimanin is the younger brother of Rinko, and the childhood friend/boyfriend of Yukikaze.

## Personality

Tatsurou is timid, shy, indecisive and insecure at times, acting very passive and non-confrontational. Rather slow to understand Yukikaze's advances as serious, he is very oblivious, unable to understand her and Rinko's intentions. He also seems to have issues putting together what underground spy work in Under Eden means, and seems naive on his checkup mission. He gets depressed and self defeatist easily, especially about his ability shortcomings, next to his father and sister. Furthermore, he needs to pushed very far to lash out in any form of anger.

Tatsurou can rise up to the occasion, helping to end the mission Yukikaze and Rinko are on, after learning the nature of it, but can easily remain silent not wanting to start a scene.

### Relationships

 Yukikaze | Tatsuro and Yukikazes relationship is described as more than friends but less than lovers.
 Kuroi | Kuroi acts friendly with Tatsuro but in reality views him as a joke. Only in the true ending of TY2, does Tatsuro gain some respect, which means nothing given that Kuroi wants to turn Rinko and Yukikaze into slaves.

## Appearance

In the Visual Novel, Tatsurou is a young man who has green eyes, brown hair and is taller than his sister Rinko.

In the OVA and his only known full body reference, he is a young man who has purple hair and purple eyes like his older sister, but he is also shorter than her.

## History

### Background

A Taimanin of the Akiyama clan and born around year 2060. As a newbie Taimanin of Gosha Village, he learned the ability to manipulate wind, but has not fully awoken and mastered this ability.

His late father was the 48th head of the Akiyama clan. Making Tatsuro, technically, the next in line for clan head. Being only friends with his one year older sister Rinko and childhood friend Yukikaze, they played around and even test kissed each other each. At times him and Rinko, would be trained by Yukikaze's mother, Mizuki Shiranui, which claimed that though they had become quite strong if they wanted to beat her they needed to learn to work together as a team and that Tatsuro needed to become strong to protect her daughter.

His skill was still far below their ability, and also because of his timid nature, he was seen more is a lower skilled Taimanin even after joining Gosha Academy. When the Tatsuro's father died, because of his lack of skill at the time, instead his sister became temporary clan head, though people did wish her to remain as such, as she also was a master of the families blade Itto-style, which she taught in the Akiyama Dojo. While Rinko and Yukikaze became more known, Tatsuro fell behind which didn't help his confidence and even after the Disappearance of Shiranui, and he joined a three men squad with Yukikaze and RInko, he was seen himself as the weakest link unable to help. Blinded by his own lack of confidence, Tatsuro would overlook Yukikaze's interest in him and make it hard for their relationship to advance much further.

### Visual Novels

In the year 2048, while on a mission, defeating Beastman, that tried to make a deal with Yazaki Muneichi, Akiyam again failed to stand out. When returning to Gosha Academy, it was stated by Igawa Asagi that he didn't meet the requirements needed to help Yukikaze and Rinko on their next special mission. Though Tatsuro never questioned too deeply, the nature of an investigation in Yomihara's Under Eden, to find intel about Shiranui. Comforted by Yukikaze out of his depressed state, he decided to become more dependable and apply for the Special Camp during that Yukikaze and Rinko passed years ago, he could be trained by Sakura and Murasaki, to use his Ninja Arts.
Before Yukikaze and Rinko, left, both tried to make advances on him, with Yukikaze unable to tell Tatsuro about the true nature of the mission involving likely her working as a hostess or prostitute. Though she was able to at least get a kiss from Tatsuro for the first time after years, she hoped for more. Rinko in turn was much more blunt of having sex but played it off as a joke after learning, he did nothing with Yukikaze outside of kissing. Tatsuro, still oblivious to the true nature, of the dangerous multiple month mission, began to train the next weeks.

In the **bad ending**, six months pass, and he is sent as a checkup together with their demon contact Zokt. Unable to figure originally out, that both women were turned into slaves and had been already deeply broken. He could not see how Yukikaze or Rinko were in lewd situations just around the corner, with both Taimanin still hiding the matter from him. At some point, both captured women fit the criteria for the VIP lounge, engaging in more and more escalating acts. Tatsuro that tried to spy around Yomihara, but was captured by Zokt and Under Eden owner Real (Yazaki Toshiji), and as an act of final cruelty shown how Yukikaze became a slave of Yazaki Muneichi and videos of their training played in the background. Tatsuro almost broke and in the Visual Novel attacked, Muneichi however, was stopped by the enslaved Mizuki Shiranui or in the Rinko's Fallen end, by his own sister. Knocked out, he was left alive and send back to Gosha Village, as a warning not to rescue Yukikaze and Rinko. This event finally broke the mind of Yukikaze, Rinko and even himself.

Depending on the bad end version playing out one year more passes from this point; he became addicted to watch the further degrading and training videos posted online of either Yukikaze or Rinko, while his room and mind deteriorated. In the ending featuring them both failing as full slaves, Tatsuro in fact remains more hopeful and still talks with Asagi about rescue. However, on his birthday, a new video arrives showing the "final punishment". Asagi hinting that they would lose their limbs, but as a reward for their apologies would be sent back alive. Tatsuro, shocked, thinks back that in front of his room stood two large suitcases and runs off.

In the true ending, after only a few weeks, Tatsurou speaks up to Asagi and Sakura, insisting early investigation and stopping the mission early on. Which results in the rescue of Yukikaze and Rinko by Asagi and Sakura.

In Taimanin Yukikaze 2 after an EVE chip is found, in the brain of Yukikaze and Rinko, now in the year **2049**. Tatsurou is sent on an undercover mission to Seishu Academy, which is connected to the Washizu Group the likely creator. Together with the veteran Kousaka Shizuru, that works as an undercover teacher. Before leaving Gosha Village, he visits Yatsu Murasaki and is given a good luck charm she had from her own brother Yatsu Kuro, a hero in Tatsuro's mind. However, right as Murasaki left Kiryu Sabato arrives quickly and snatches the good luck charm for himself, forcing a trade for an unknown bottle that could be useful if things turn grim.

Having learned new skills, including invisibility with his wind art, became handy on the mission. Investigating the headmaster office of Washizu Shigeru, they find decoded data, which later hints to the Washizu Material research facility. While being a student, Tatsuro isn't able to learn much more new information as he is not granted access to the advanced classes, something he learns from his forced "friend" Morita Kazutoyo.

While investigating the research facility, Tatsuro and Shizuru, are attacked by a large spider Animal Drone and forced to flee the location. A mysterious rubber coated lady appears, which attacks them both with Shizuru getting sliced and injected with a strong aphrodisiacs poison, but the attacker does not hunt them further as they flee. Shizuru starts to ask to have "comfort" otherwise she could die from the poison, Tatsuro will the bad end routes just give that to her something he views himself as cheating on either Yukikaze or Rinko.

In the bad ending, this leaves an EVE chip in Shizuru undiscovered and her corrupted, halting the investigation progress. Rinko and Yukikaze are sent as further support but also fall victim to the rubber coated lady and are infected by new Eve chips, which turn them into plaything and slaves of Morita Kazutoyo, Inui Hideo and the true master mind. Tatsuro, unable to find out this is happening also infected by an EVE, runs along. Until in an investigation with Shizuru and either Rinko or Yukikaze, all is revealed, and he is beaten down and send back to Gosha Village as a warning. Something that ends with the same mental state as shown in TY's bad ending and him watching again training videos.

In the true ending, he uses Kiryu Sabato bottle which contains a small bug-kiryu, which he puts into Shizuru for it to cure her. As the EVE chip is found, and more info becomes now fully confirmed, Tatsuro is able to convince the Taimanin on a full raid on Seishu Academy and the Washizu Material research facility. Yukikaze and Rinko appearing as the spearhead, while Tatsuro guides the operation. All four Taimanin, Rinko, Yukikaze, Tatsuro and Shizuru reach a large room in the research facility and come face to face with Kuroi Ryuuji that turns out to be the true master mind and Incubus King.

While Tatsuro fights against Inui Hideo, Shizuru takes on Washizu Shigeru both are able to kill their foes. With Rinko and Yukikaze, able to blast the true form of Kuroi away, while Tatsuro protects Yukikaze with his wind art. The group, thinking they won, celebrate Yukikaze giving Tatsuro a kiss. Shizuru revealing that Rinko has a thing for Tatsuro, with a bit more light banter. However, the voice of Kuroi the Incubus King is heard once more and without any damage he appears once again, this time with the rubber lady next to him. The woman revealed as Mizuki Shiranui and confirmed as loyal to the King even suggested that Yukikaze and Rinko would make great slaves. Kuroi acknowledges even the strength of Tatsuro with a grace but still states Rinko and Yukikaze will join their ranks, before teleporting away with Shiranui.

In Taimanin Asagi 3, Tatsuro appears again around four years later, in the year **2082**. When Gosha Academy is under attack of the Kanda Brigade, and Rinko and Yukikaze are on undercover missions. Tatsuro is sent by Murasaki and Sakura to save trainee Taimanin, using a mountain path. This fails as a large part of the army was waiting, killing half of the people. Tatsuro fate here becomes unclear as he does not appear again however, outside of game material reveals; originally he was supposed to be shown up later on, to confirm him alive but the use of a female voice actor, let to a rewrite, implying it to be his sister instead.

### Timeline TABA

Taimanin Asagi Battle Arena takes place instead of TA3, otherwise follows the same events as above. TY did end on a happy ending but TY2 works on an in between route, in which Tatusuro has watched recordings only existing in the bad ending routes of TY2 but all characters are still active in Gosha and not brainwashed. The game plays between **2082** until around **2086**.

In multiple connected "What If" scenes, Tatsuro has been captured by the Fuuma Organization. He's researched on by Kiryu Mikoto as her favorite pet project, using a Mind Probing Machine, to gain intel or entertainment. In these scenes Fuuma Kotaro dives into Tatsuro's memories and sees, from Tatsuro's perspective, an unseen scenario of TY2. In this scenario, he is sitting in his dark room watching the training videos of Yukikaze, Shizuru and Rinko.

Fuuma Kotaro tends to find entertainment in these, but also calls the sleeping Tatsuro a cuckold.

### Timeline RPGX/Action

Is mentioned as Akiyama Rinko brother offscreen and childhood friend of Mizuki Yukikaze. As TY and TY2 do not play out in those timelines, most of the characters development has not taken place. ISince he is only mentioned in an incidental way he seems to have almost no impact on the life of Yukikaze and Rinko. Fuuma Kotaro seems to have somewhat replaced him in the role to an extent as Yukikaze interacts more with him, although the relationship those two have seems to not be romantic.

Later units, fully remove the friendship to Yukikaze and only mention him as a brother of Rinko in passing.

## Additional Material

* Tatsuro in the visual novel had brown hair, while in the OVA he was given blue hair to connect him more to Rinko. There are some extra flashbacks that exist in the OVA and some imagined dream-sex with Yukikaze, but scenes with him and Yukikaze's mothers are removed. He gifted Yukikaze a necklace, she wears until her will is broken completely. The scenes featuring his arrival and the hidden actions of Zokt with Yukikaze are removed. Different to the VN as well, he will not try to attack Yazaki, so Mizuki Shiranui never makes an appearance. He just runs away on his own, crying. This makes this version of Tatsuro, even more pathetic than his visual novel counterpart, further reinforcing his visual novel archetype as a cuckold protagonist.
* Appears in manga adaption, and goes into a bad ending route.
* In the light novel, both Rinko and Yukikaze are not fully corrupted. Near the end of the Route, Rinko acts like she has been broken and gets close to Yukikaze and Tatsuro to teleport them away in exchange for her life, as the magical contract will take her limbs. Shiranui appears and knocks out Rinko before she can do so, Shiranui afterward has her way with Tatsuro while Yukikaze is forced to watch. At some point, she injects Tatsuro with an experimental drug, this turns him almost primal, and he impregnates Yukikaze, Rinko and Shiranui over hours. All three start to become broken by Tatsuro, but Real mentions that he will perform an autopsy after he dies, to research that new drug. Yukikaze hears this and, in her daze, awakens to a power which could also be connected to the new life growing inside her. Lighting floods a large area of Yomihara, leading to a blackout, with the lighting destroying the nanobots of the Magical Contract in the body of everybody and kills targeted Zokt and Real. A report is later given to Asagi, which confirms that Shiranui, Yukikaze, Rinko and Tatsuro have disappeared, but a sighting of lighting suggest they are still alive but have become Rogue Taimanin but also free. It could be assumed his mental state recovered somewhat.
* In some of the Drama CDs, he is mentioned by either Rinko or Yukikaze.

## Trivia

* His face isn’t shown in the visual novels, except for a moment in the bad ending of Taimanin Yukikaze.
* His importance specially in Action Taimanin and RPGX has been reduced, as the relationship between him, Rinko and Yukikaze seems to have less, to no relevance because of Fuuma Kotaro. In the Online Universes, he is a footnote in bios as a, fully stagnated old friendship, or just a family member.
* In the first game he shows up very little, but in the second one he plays more of a role, as he has his own route which decides if Yukikaze or Rinko's bad end route start.
* His eye color in the game is green, but purple in the OVA. Most people, still portray him with blue hair but his hair has been brown in all appearances of the visual novels.
* Tatsuro was basically created as an NTR character, getting cheated on or cheating himself. However, this role as been almost entirely been removed beyond the release of TABA.
* He was mentioned in Taimanin Asagi 3 while Gosha Academy was under siege, ordered to escort Taimanin trainees through the mountain pass. As the attacking soldier had decapitated and killed multiple guides later on, his fate is unclear, but he is not explicitly named as dead. Originally he was supposed to be shown up later on, to confirm him alive but the use of a female voice actor, let to a rewrite, implying it to be his sister. This still leads to an error, as Rinko and Yukikaze are mentioned to currently be undercover.
* The tag Minor Characters only applies to him in Taimanin Yukikaze (1)
* In TY2, Yukikzae is impressed by his ability to blend into any crowed and not be questioned. (If this is thanks to his sneaking abilities or his background character energy is unclear)
* His wind blades are less effective against armor.
* Kiryu Sabato likes him, in his special way, because Tatsuro has become one of Murasaki's favorite student. They also later share the quality of being a younger brother in TABA.
* In the neutral bad ending, Tatsuro did not give up and even after losing contact with Yukikaze and Rinko searched one more year. It is mentioned that when, Rinko and Yukikaze arrive it is his birthday.

### Etymology

* The name **Tatsuro** means "achieve" (達) (**tatsu**) and "son" (郎) (**ro**).
