Fake Holy Grail: I Will Attack in the Form of a Black Hole

Wearing "Kamen Rider Build", Haiwen had just completed his mission as the most slutty and romantic villain Evolto when he was pulled into the world of "Fake Holy Grail War" by a ray of light and became a follower of Tsunade Chun, overthrowing the original Pale Knight. "You said I'm not a rider? You're right, I'm just a passing Kamen Rider... Villain." "The other side has summoned Qiu Hai, why are you still bothering so much?" "All the heroic spirits and masters who participated in the Holy Grail War, do you want to die?" In this fake Holy Grail War composed of thirteen knights, there are as many flash-level heroic spirits as dogs, and god-level heroic spirits are everywhere. Haiwen still maintains the saucy attitude of his previous life, and his nature of fishing has never changed. In addition to fishing, plotting behind the scenes, and destroying the plans of those behind the scenes, he also has one goal - to become the biggest villain. "I just want to devour the planet, why do everyone come to attack me? But it doesn't matter, I will attack in the form of a black hole, henshin (transformation)!"
