Sou Fueki/Kamen Rider Wiseman

Sou Fueki (笛木 奏 Fueki Sō), better known as The White Wizard (白い魔法使い Shiroi Mahōtsukai)/Kamen Rider Wiseman (仮面ライダーワイズマン Kamen Raidā Waizuman)[1], is an enigmatic, white-robed magician that gave Haruto the means to become Kamen Rider Wizard. He also sometimes helps and oversees Haruto's evolution from a distance.

In Wiseman's Truth, he was revealed to also be Wiseman (ワイズマン Waizuman), the artificial Carbuncle Phantom and the equally mysterious leader of the Phantoms, who take no course of action without his permission. Thus, the Chief Phantoms Medusa and Phoenix must meet with the Wiseman to discuss their plans, seeking his approval.

Before he became The White Wizard (Kamen Rider Wiseman)/Carbuncle (Wiseman), he was a particle physicist at Kirimine University (霧峰大学 Kirimine Daigaku).

After a lot of calculations made by Gremlin, he realizes that his goal wasn't to give birth to more Phantoms, but to find more magicians in order to revive Koyomi.

At the end of the series, a final battle with Kamen Rider Wizard Infinity Style drains him of his energy. Shocked, he was murdered by Gremlin.
