Kamen Rider Electro, who is killing time every time? Thank you, everyone.

Ryutaro's sister's boyfriend Sakurai fought, sacrificed himself to protect time, and let himself disappear in time, in exchange for the power of Zero North, and called her auxiliary power in her youth, and finally disappeared completely. More than a dozen words are about the young Kudou coming to power. Generally, in order to distinguish two people, the young one is Kudou and the old one is Sakurai, which is what the play calls it.
