Kyosui Izumi (泉 京水 Izumi Kyōsui) was a flamboyant gay man with sadomasochist quirks member of NEVER who serves as Katsumi Daido's right hand man. In Kamen Rider W Forever: A to Z/The Gaia Memories of Fate, he becomes the Luna Dopant.
Izumi is a gay man with sadomasochist quirks and was once a yakuza subordinate until he was betrayed and fatally stabbed in the chest. After he was revived, he fell in love with Katsumi as he was the last thing he saw before his death, tending to call him 'Katsumi-chan' and get jealous of anyone who gets too close to him. Should anyone question Katsumi's motives, Izumi would always stick up for Katsumi and explain his reasons. He would follow Katsumi without question and went on nearly every mission with him.
In the Futo City mission of the retrieval of the 26 T2 Gaia Memories to convert all of Fuuto into Necro-Overs, he gains the T2 Luna Memory, and during his last clash with Kamen Rider Double, he proved to be a resiliant wall, until he fought Kamen Rider OOO and was defeated by the Rider's OOO Bash Scanning Charge, turning into dust instantly.
