Takeru Tenkuji/Zi-O

In 2015, Takeru Tenkuji (天空寺 タケル) was Kamen Rider Ghost (仮面ライダーゴースト), until the creation of Another Ghost erased the Rider from history.

Another Ghost
As a result of the Time Jackers' actions, Takeru loses his powers as a Kamen Rider but retains his spiritual abilities. Alongside members of the Mysterious Phenomenon Institute, they investigate the disappearances Another Ghost has perpetrated for three years until Zi-O and Geiz get involved.

With Sougo's spirit separated from his body, Takeru's Ridewatch allows him to perceive the youth before Narita uses Shiranui to render his spirit visible to mortals. Takeru takes Sougo's place physically to travel to 2015 in the Time Mazine with Sougo to prevent policeman Makimura from dying while saving his sister and being turned into Another Ghost when he succeeds. Sougo returns to his body, but as Takeru is attacked by Heure, he is rescued by Makoto, who reminds him that he is a Kamen Rider.

He temporarily regains his powers but fails to prevent Makimura from becoming Another Ghost, causing Sougo's soul to separate from his body again. Despite this, both Takeru and Makoto manage to power down their Rider forms immediately before Another Ghost's presence negates their transformation again.
