Kuroi Ryuuji

Kuroi (Incubus King) is the true main antagonist of Taimanin Yukikaze and Taimanin Yukikaze 2.

He is introduced, as a late third year student, in the special scholarship department of Seishu Academy, with possible family ties to Washizu Shigeru. His true identity is the King of Incubus and Succubus, ultimately responsible for brainwashing Shiranui. His aim is to take over the Dark World, turning Taimanin like Rinko and Yukikaze, into his slaves and soldiers.

Personality
In his civilian disguise, he is always top and class but solitary and disliked as nobody can tell what he is thinking. Careful and cunning, he doesn't show his true intentions or nature easily, only slight dark smiles give away some of his intentions.

Kuroi is a rather rude man of few words, that likes to dominate. He searches out powerful Taimanin and uses sex to brainwash them into his army to gain more power. He is extremely careful, even more so than most villains in the series. Using underlings like Yazaki, Shiranui, Real, Washizu, Inui and Shizuru as proxies, while he remains in the shadows.

In a fight he reacts calmly and precise, testing his enemies more than fighting pretending to be in danger, even if that really isn't the case.

Appearance
A tall darker skinned pretty young man with white hair.

His demon form is a black winged Lovecraftian monster. Standing at around 10 Meters, with two horns, giant hands with sharply tapered fingers. On his back he has bat-like wings that tapered to sharp points at the end. Tentacles come from his mouth, stretch far from it. His tail splits into two, partway down and is thicker and longer than any snake.

History
The Incubus King existed for a long time, trying to become the ruling force in the Dark World over Edwin Black. However, he has so far avoided a direct confrontation. Having ordered Mizuki Shiranui brainwashing by Real originally 5 years before TY, he later in TY2 does it himself in a very short time.

Pretending to be related to Washizu, enjoying nepotism in Seishu Academy but nothing more. Washizu was in reality his loyal servant. Kuroi used the Washizu Group and Seishu Academy to create technologies like the EVE chip and Drone weapons for him as well as transform people into loyal subjects. Having pulled also the strings of Yazaki Muneichi rise to power and happenings in Under Eden with Real, as a way of distributing the Eve chip. He ordered the construction of the Washizu Material research facility, which he also used as a temple for himself.

Kuroi appears rather abrupt in the true ending of TY2, unlike the bad ending routes, that gives him more of a spotlight in the Rinko route. Waiting at his office while the raid of Taimanin on Seishu Academy is ongoing, just having the loyal subjects Shiranui, Washizu and Inui on his side. Revealing himself as the Incubus King, he fights both Yukikaze and Rinko at the same time. Able to counter most of their attacks until he got caught off guard, revealing his true form as a reward. Able to block or heal from any normal attack, Yukikaze overcharges a lighting art that with the help of Rinko, is transported behind the Incubus king‘s barrier, right after Tatsuro protects Yukikaze of an incoming. Seemingly burned to death, by the combination of Yukikaze and his own attack and reduced to nothing, the group of Taimanin celebrate.

However, shortly after that his voice is heard again, saying he was „impressed“ but showed no injury at all. Telling Shiranui that appeared next to him, that Yukikaze and Rinko are superb, and he will remember them. Saying that just as Shiranui wished, they will join their ranks soon. Saying farewell and even acknowledging Tatsuro existence, he disappears together with Shiranui with no trace. Leaving Yukikaze shocked behind, seeing her mother for the first time in years but also as a loyal solider of that new enemy.

Timeline TABA
In Taimanin Asagi Battle Arena he makes secret deals with Fuuma Danjo and Task Force G, strengthening his forces against Nomad. Waiting for Danjou, he gets attacked by Koukawa Asuka and Koukawa Oboro, that try to assassinate him but are unable to do any damage. After they start to flee, he sends his loyal assassin Mizuki Shiranui after them. Fuuma Kotaro and him never encounter each other.

Timeline RPGX
Has not appeared. "The Incubus King" or "Phantom King" is mentioned as the leader of the Incubus Faction but is claimed to be dead of a natural cause in chapter 38. Mizuki Shiranui is suppose become the Queen but strong Incubus and Succubus are in conflict over it. An heir of the Incubus King is mentioned, which was moved and hidden by Edwin Black and his butler Kii. It isn't clear if the King really is dead and if in RPGX, it is even the same person. However, this version aimed to make Shiranui into his slave, around 3 years after her marriage to her husband and having Yukikaze. Haunting all her dreams for many years, with lewd visions of edging, her husband never waking up to give her any release. Which eroded her will, even if she never remembered the dreams.
