Anime Crossover: Starting with Cronus, I'm Terrifyingly Strong

[Starting with Cronus + Kamen Rider + Crossover Anime + Tanzaburo Tojima + Nisekoi + Multiple Heroines] Transmigrating to various anime worlds, Shiraishi Shin begins as Kamen Rider Cronus. In the realm of the God of Time, day and night are but a thought away, and time stops and flows backwards only for him. On campus, Shiraishi Shin is a gentle, cheerful, and sunny male god, but when facing strange people, he is a cold-blooded judge and a grim reaper. The city's impurities, the Amazon lurking in the shadows, the constellation apostles on campus, the Shocker monster causing chaos, and monsters from other knight worldviews in the dimensional rift, and the BOSS. When he is Kamen Rider Cronus, he puts his index finger to his lips and says, "Shh, during the trial, the scene must remain serious." When he was Kamen Rider Eternal, he gave a thumbs-down sign and said, "When you get to hell, just say my name, Shinigami, and you can skip the toll." When he is in Kamen Rider Evol Black Hole form, his right hand spins like a black hole: "This day next year will be your death anniversary, Ciao." When he was the Blade of the God of War, he pressed his thumb down on his index finger and said, "Don't misunderstand, I just want to kill you all, or be killed by you all." When he is Oma Zi-O: "If you do not bow to the king, you have already lost your true destiny. Your name is on the Reincarnation Stele. Bow with each step. If you are devout and sincere, your sins will be halved on the road to rebirth." All sorts of weirdos: What? I'm taking on the Knight Boss one-on-one? ... The tentative list of female leads includes: Alisa who speaks Russian from time to time, Shiina Mahiru, the angelic neighbor, Okada Yuriko, the eccentric Takumi, Kirisaki Chitoge, Kato Megumi, and Kasumigaoka Utaha, the black-stocking fanatic.
