魔王と百合

Princess, hero, priestess, witch, and maid. If you had to choose one to be your queen, who would it be? The war between humans and demons had just ended, but the world still feared more conflict. The only way to assure peace is for the Demon Lord (female) to take a human queen! Which heroine will you choose? Your choice will help guide the story to its conclusion! It's a new kind of reader-participation harem comedy! (Source: ComicWalker, translated)
