YMMV / Infinite Apostles and Twelve War Girls

• Complete Monster: Second Prince Razzle of the Kenz Kingdom murdered his stepmother, took his infant twin half-siblings to a random orphanage until they came of age, and seized his half-sister to be his personal assassin and punching bag while his half-brother is abandoned in the slums to fend for himself. Razzle has a loathing for his adopted brother and does everything humanly possible to destroy him. When said brother succeeds in crafting the knight order, Razzle goes to the king and requests said knight order be transferred to him; when that fails, Razzle proceeds to kidnap the order from their homes and have them used as test subjects for his grand plan of turning his country's entire population into undead monsters that can't be freed. Then Razzle puts his plan into motion by kidnapping one of Yu's love interests, Linda; poisoning his own father, the king; and murdering his accomplice Kyle Polette, so nobody can shut him down. Razzle tries to sacrifice both his half-siblings and Linda to an Ancient Artifact to launch a Zombie Apocalypse and Take Over the World.
• Crosses the Line Twice: Hilfy, who looks like a child despite being centuries old, looks like she's propositioning Yu for sex, badgering him until he accepts? Squick. She whips out scissors and threatens his family jewels when he relents, and he then drops to the ground apologizing? Black Comedy
• Growing the Beard: The early chapters look like a generic isekai harem story, but by the time the manhua reaches chapter 33, things really get good, with the protagonist actually having to struggle to keep his lady friends from the threat of lethal harm, with enemies having game-breaker abilities of their own.
