Alfred then deduces Kaito's identity, contacting to Oren to take care of him. By the time Kaito finds Shapool, the two are attacked by Alfred who threatens to kill Shapool while transforming into Kamen Rider Tyrant.

In the end, Shapool writes a letter to thank Kaito for saving him from Alfred's threats and taking what Kaito has taught him, to believe in friends and to fight for what is right, before he leaves Zawame City for reuniting with his father. Kaito went to his parents' tomb at a cemetery, and later walks out as the flowers were left onto his parents' tomb.
