Akiyama Tatsuro

Tatsurou 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. 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.

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
A newbie Taimanin of Gosha Village, he learned the ability to manipulate wind but has not awakened to his clans ability. His late father was the 48th head of the Akiyama clan however, after his fathers death he wasn't selected as the next as he is seen unfit so far. Being childhood friends with Yukikaze and his sister, he trained with them since youth but is far below their ability and in his childhood he kissed both Yukikaze and Rinko as a "test".

Having not met the requirements, after a mission defeating demons, acting too passive and wanting Yukikaze to depend on him more, he decided to apply for Special Camp. He is teached by Sakura and Murasaki, training his Ninja Arts. Not able to understand that both Yukikaze and Rinko want their first times with him, he doesn't grasp the nature, of the dangerous multiple month mission to find Mizuki Shiranui (Yukikaze's mother) in Yomihara's Under Eden.

In the true ending 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 the bad ending he will be captured by Real and Zokt, while doing a checkup on the mission after six months. Unable to figure originally out that both women were turned into sex slaves, he will directly forced to watch Yukikaze having sex, in the VIP area of Under Eden, while videos of her training are playing in the background. Attacking Real (owner of Under Eden) and his brother Yazaki Muneichi in anger, he gets stopped by Mizuki Shiranui and in Rinko's Fallen end also by his own sister. Easily defeated, even with his wind abilities, he is knocked out and set free right after that. Real and his brother, wish to send a message to Asagi, not trying to rescue Yukikaze and Rinko again. He spends most of his time alone in his room, masturbating to videos of both women being trained and degrades.

In Taimanin Yukikaze 2 he goes on an undercover mission in Seishu Academy, together with the veteran Kousaka Shizuru. Depending on the use of Kiryu Sabato cure, this can lead to a simular bad ending or a victorious fight against the Incubus King.

OVA
There are some extra flashbacks that exist in the OVA and some imagined 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, being turned into a sex slave by Yazaki Muneichi. 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.

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, Battle Arena and RPGX have been reduced to mentions as the relationship between him and Yukikaze seems to have less to no relevance because of Fuuma Kotarou.
 * 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.
 * 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 show 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.
