Yandere Dark Elf: She Chased Me All the Way From Another World!

Hinata the human's already defeated the demon lord in the world he was summoned to and got sent back home shortly after. Sure he'd see his older lover Mariabel the dark elf again one day, he didn't quite expect her to reach out of his TV a month later (likely breaking summoning records). Now his once ex is forever back and wants a continuation of what they had going back in the discriminatory world he saved her in: daily sexual intercourse. But can the high-schooler even hope to keep up?
