Kirihiko Sudo

Kirihiko Sudo (須藤 霧彦, Sudō Kirihiko) is a character in Kamen Rider W. At the beginning, he was known by his original surname until changing it to Sonozaki after he married Saeko Sonozaki. In later episodes after he was killed by Saeko he is referred to by his original surname. Despite being a member of the Museum and Sonozaki Family, Kirihiko is more of a neutral character due to being unfamiliar with the Sonozaki's plans.

Background
When Kirihiko was a child he and his younger sister, Yukie attended a kindergarten in Futo City. It was there were he invented the future mascot of Futo, Futo-kun. Years later, an adult Kirihiko got a job as one of the Museum's top Gaia Memory dealers. He also attracted the attention of the eldest daughter of the Sonozaki Family, Saeko.

Personality
Kirihiko has a professed love of Futo City, to the extent of creating its mascot, Futo-kun in his childhood. He would do anything to help Futo. Unfortunately this lead to him getting a job for the Museum, unaware of its true intentions. After marrying Saeko, Kirihiko does everything in his power to help his new family (e.g. assisting Saeko in Gaia Memory distribution, dealing with Kamen Rider Double, and trying to help Wakana Sonozaki with her stalker problem). When he learned of the Museum's goal, he decided to rebel against them even helping his 'rival' Double destroy the evolved Bird Memory. Before leaving for good he tells Saeko that he can't help the Museum anymore but still loves her and tried to get her to come with him, to no avail.

Part in Story
When first introduced, Kirihiko became married to Saeko after she spared him, unlike some of her other boyfriends. He is then given a Gaia Driver and the gold Nasca Memory to become the Nasca Dopant. For most of his appearances, he is often with overseeing events on the Gaia Memories and fighting with the Sonozaki family against Double, who he sees as a rival after seeing one of his two identities (Shotaro Hidari) transform. After going through secret training to his Level 2 powers and finding the temple underneath the Sonozaki Estate where the Museum's ambitions are explained to him by Ryubee while suffering near-lethal side effects for reaching Level 2, Kirihiko decides to fight against the Museum and helps Double defeat the Bird Dopant. He tries to get Saeko to come with him out of love but instead she kills him as a threat to her own plans for the Museum while taking the Nasca Memory with her. His death then becomes the main point of the Yesterday Dopant case.
