Ryu Tenkuji (天空寺 龍 Tenkūji Ryū) is Takeru Tenkuji's late father. He was a superior Ghost Hunter and gave the Ore Ghost Eyecon to Takeru.

In Kamen Rider Ghost: ~Memories of the Future~, he is revealed to be able to transform to The Red Kamen Rider Ghost (紅の仮面ライダーゴースト Kurenai no Kamen Raidā Gōsuto), namely Kamen Rider Zero Ghost (仮面ライダーゼロゴースト Kamen Raidā Zero Gōsuto). [1]

Character History

Ryu, Igarashi and Saionji work together.

Ryu Tenkuji once worked together with Chikara Saionji to research the Ghost Eyecons 10 years ago. However, Saionji secretly used a human experiment on the Fukami siblings on their back to open the Monolith's Gamma Hole to enter Gamma world, trapping them inside for 10 years, meaning that he has betrayed Ryu and Kenjiro Igarashi, thus eventually sided with the Gamma. Ryu was later killed by Adel, though not before arranging for a Ghost Eyecon to be delivered to his son 10 years later. Before his death, he entrusted a pendant resembling Miyamoto Musashi's tsuba to his son. Eyes Open! It's Me! Conciliation! All Resolutions!

Ryu watches over his son while he has troubled dreams about his supposed doom.

On the last night of Takeru's life, the young Rider was in sorrow that he would die on January 10th, 2016, Ryu appears in spirit form when his son drifts off to sleep to watch over him. After Takeru crosses over to the land of the dead, Ryu speaks with his son on how proud he is of him and apologizes for dragging him into the life of a ghost hunter. He then tells his son that he must continue to protect the lives of humanity so that they can have future that burns as bright as Takeru's life. Ryu then gave his own soul to his son by merging with Takeru to give his son more time and gain the power of Toucon Boost Damashii and the Toucon Boost Ghost Eyecon. Heroic! A Man's Resolve!

He was later killed while trying to shield his son's 2005 self from a projectile coming from the Da Vinci Eyecon. Before dying, he entrusts a pendant resembling Miyamoto Musashi's tsuba to young Takeru, as older Takeru and Shinnosuke return to the year 2015, before Ryu tells his time-displaced son not to worry that he deserved this fate and will always be with him as a spirit in the future.
