In Blazar: I Convinced the Yandere Queen from the Start

Truck driver Lin Feng accidentally transmigrates into the world of Ultraman Blazar, becoming an unaffiliated research assistant for the SKaRD Special Kaiju Countermeasures Unit. Armed with the god-tier golden finger known as the Myriad Star Compass, he can fuse the powers of giants from countless worlds. When an electromagnetic monster arrives and the ancient yandere empress You Mi awakens, Lin Feng refuses to take the usual route. With physical purification in one hand and a slow, gentle courtship in the other, he turns an apocalypse-threatening crisis into an everyday romance where light and darkness join forces. As an army of interstellar raiders bears down on them, Lin Feng joins forces with the tsundere empress and sets the galaxy ablaze in the name of the aurora!
