Event Disappearance Shiranui

Corrupted by the Incubus King

The **Disappearance of Shiranui**, was the sudden capture of the elite Taimanin, Mizuki Shiranui, the mother of Mizuki Yukikaze. Nobody knew of Shiranui's fate and if she was still alive or dead for the longest time.

An event relevant for the old canon and the games Taimanin Yukikaze, Taimanin Yukikaze 2 and Taimanin Asagi Battle Arena. Playing out roughly during Taimanin Asagi 2 or Taimanin Murasaki, when Igawa Asagi returned as a captain and Yamamoto was in the leader position. Finding Shiranui is the main goal of TY and even TY2 to a lesser extent.

## Event Timeline

### Pre Event

Mizuki Shiranui was long respected as an elite Taimanin, an ideal many tried to reach, with strength only rivaled by the almighty Asagi herself. When she married and had a child at a very young, she retired but still would help Asagi as an advisor.

However, thanks to her known skills, she became a target for the Incubus Faction, which wished to turn her into a loyal pawn. A new mission, requested by a politician, an unnamed ruling party member (Yazaki Muneichi) put her out of retirement. Muneichi had ties to the Incubus Faction of Kuroi Ryuuji. Not long after she trained with the teen, Mizuki Yukikaze, Akiyama Rinko and Akiyama Tatsuro and gave them some words of advice, she made her way to Yomihara, the underground city below Tokyo.

* In RPGX, Incubus King Kuroi has been exchanged for Incubus King Kamadeva. Kamadeva also send her lewd dreams for years to corrode her will. Muneichi is mentioned in voice clips to be somebody she will not forgive, but no information is given. Speculation wise, this could mean that the trap was the same, and she encountered Muneichi in RPGX.

### Event

Her mission in Yomihara turned out to be a trap, and she was captured by an unnamed enemy, which is only given an image in the OVA. Shiranui became the target of the Incubus King, Kuroi Ryuuji, in the main canon. He gives Shiranui to Real (Yazaki Toshiji) of Under Eden, who is his pawn and brother of Yazaki Muneichi, nephew of Washizu Shigeru a powerful figure in Kuroi's group.

Real performed Body Modification and other training methods to break Shiranui's will. Her husband began to search for her but died 4 years after on a mission. Meanwhile, Yukikaze continued to improved her skills to find her mother one day. Against all odds, Shiranui remain in control of her own mind for up to 5–6 years. However, nobody was able to gain any intel about her location until 5 years had passed.

After a violent exchange between Yukikaze and Muneichi, Yazaki desired revenge and created a trap for Yukikaze. Leaking information about her mother in Under Eden, while working with his brother and the informant Zokt, to make sure should Yukikaze would investigate and fail. When Yukikaze and her partner Rinko arrived, they were forced into a Magical Contract, that enslaved them. Only in the true ending, where they freed after a few weeks of Virtual Reality training, thanks to Asagi and Sakura arriving and breaking the contract. In the bad endings, Shiranui is broken in the ~6 months of her daughter's investigation.

However, in the true canon, Real's failure to break Shiranui resulted in Kuroi Ryuuji moving her to the Washizu Material Research Facility and left her training to his Incubus for at least a year. This again ended in failure, as Shiranui's will was too strong until the Incubus King personally started to take full note and was able to finally brainwash Shiranui into his loyal subject within a week. Though TABA shows some of the scenes, it is only implied that she had been turned into a Succubus herself at that point.

In the true ending of Taimanin Yukikaze 2, Shiranui uses a rubber suit to attack Akiyama Tatsuro and his partner Kousaka Shizuru, infecting her with an EVE chip. In the true ending, a large raid against the Washizu Material Research Facility takes place. Yukikaze and Rinko fight and beat the King, though his ability to regenerate even after complete disintegration, makes their victory short-lived.

Shiranui arrives but does not address her daughter, instead she suggests that Yukikaze and Rinko should join them as soldiers, for which she's praised. Stating that the whole fight with the King was only a test, Shiranui disappears, leaving her shocked daughter shocked.

* In RPGX, she was also captured, but here it is by Kamadeva. It is not clear if she ever enters Under Eden and is instead brought to the Dark World and the capital of the Incubus/Succubus, Flame End. Her mind is broken over the 5–6 years, and she becomes loyal but still retains some of her humanity. Kamadeva, wishing to protect his daughter and wife, gives up his life to rant his own daughter some of his powers. In order to make sure both are unharmed after his death, he allows them to leave and appoints Shiranui as the next Queen. With Kamadeva's death, this starts a whole internal war of succession, with demons like Ambrose and Ishtar forming factions for and against Shiranui until, a new enemy of Ereshkigal and her Hades Incubus/Succubus arrives, which units the fronts. Asagi learns about these conflicts and the new "Phantom Witch" suspecting it is Shiranui and sends Fuuma Saika, which supports Shiranui's side against the Hades types, to gain some information from her. Shiranui herself, now subscribed to the idea of bringing dark bloody justice, even if it means to lose what tied her down as a human, she informs Asagi over Saika, about her intentions and apologizes to her former friend.

### Post Event

In normal canon, TY2 was the last game ending on a cliffhanger. However, TABA does show Shiranui again as the assassin and guard of Kuroi. Fuuma Kotaro is aware of her, but TY2 might have happened differently in that game. It is never stated here if Yukikaze saw her yet. Shiranui shows multiple Succubus abilities, and it is stated that she has the aura of a demon around her. Like in the main canon, she is very murderous and evil.

* In RPGX, Shiranui is able to awaken to the full power of Kamadeva by cutting all mental human ties, she still had and is turned into a noble Succubus and is crowned as Phantom Queen of the 9 Nobles, leader of the Incubus and Succubus faction. Yukikaze is not yet aware of her mother's actions or that she is alive. Asagi and now Kotaro, have kept that information, currently uncertain what to do. Shiranui also has entered a conflict with Ereshkigal of the Hades Incubus/Succubus, the former Phantom Queen before being sealed and cursed by Kamadeva. Ereshkigal is also supported by the Teutates the Corpse Lord of the Wraith.

## Trivia

* The OVA shows, that the main canon version of Shiranui is much more unhinged and killed even a clone of Mizuki Yukikaze but not knowing that she was a clone. It made clear that the thought was what counted.
* Currently, the only version where she is not kidnapped is in Action Taimanin, which offers insights on how her life probably was before her disappearance, as well as showing a what if scenario where she remains a Taimanin.
