Honkai Impact: Is It Kamen Rider? It's the Valkyrie!

[The author's composition is extremely complex and there are many original characters appearing, so please read with caution. "Kamen Rider" + "Yandere Male Protagonist" + "Group Portraits" + "Dark Belly" + "Multiple Dimensions" (Honkai III? Kamen Rider? Just a perfect match!) Before the third Honkai Impact, something happened in Changkong City... Honkai Impact? However, no Honkai energy was detected, but in order to protect the people, Captain Himeko and her team received instructions from their superiors to investigate and protect the people. At the end of the operation, a baby was crying helplessly 600 meters away from Changkong City. The instruments on the Tiberian detected this weak signal. Although the rescue mission had been completed, It was completed, but it was impossible to abandon this weak baby, so Himeko took it aboard the Tiborian. During the discussion with the team members and herself, Himeko made a decision that she would adopt this abandoned baby, and this abandoned baby is our protagonist. Because of his appearance, the world has changed and become better... Probably... (Our protagonist, he makes his own driver, but it is not a driver like War Rabbit, but uses a white crystal to transform using the internal energy. In terms of strength, the overall strength is the same as the Herrscher. If the second rider participates in the transformation, the strength will be higher than the Herrscher.)
