Hideyuki Kagawa is the central antagonist of Kamen Rider Ryuki, being the main antagonist of the Tiger and Imperer arc.
He is a professor/scientist at Seimein University who used to live a normal life until stumbling upon the notes of a student named Kanzaki Shirou.
This led Kagawa to embark upon a delusional quest to stop Kanzaki from giving his sister Yui more life. Viewing the girl as a monster due to being a mirror being he soon created a cabal who wanted to "save" people from this.
History[]
Kagawa was a normal professor at Seimein university who at one point bumped into Kanzaki Shirou and noticed his schematics for the rider system. Although getting a glimpse his mind instantly saved what it said, remembering it enough to create the alternatives. Through the years he discovered more about the mirror dimension and got Toujo and Nakamura his students to help him seal the mirror dimension.
He had a family too a wife and young son who he concealled his activities from for their own safety. While doing so he told his students that they would be heroes but have minimal casualties. Yui Kanzaki was investigating her brother's old lair where she found Kagawa who told her that nothing was happening here, before stopping her when she got to the mirrors. Shinji or Kamen Rider Ryuki thought they were potentional allies since they wanted to destroy any more of a chance the mirror world had to erecting chaos.
Soon though Shinji didn't want to affiliate with them since they seeked to slay Yui preventing her from unleashing mirror monsters into our world. Nakamura at one point wanted to destroy the mirrors but even though the former's colleagues were killed by Shirou's action, Kagawa wasn't out for revenge just simply to save Earth. Toujo soon ended up killing Nakamura for what Kagawa was growing concerned off.
Later Ren found him and they fought, with Kagawa explaining his intentions. Revealing he wasn't a tyrant and just wanted peace. Being even against killing Shinji earlier he refused to slay Ren. Although Kagawa had his philosophy challenged when Shirou told him to stop being an alternative or his family would die. They survived thankfully but later he used this to show Toujo compassion.
This would be to no avail when he was about to destroy Yui, Toujo turned on him and killed him.
