What, the Valkyrie's True Identity Is...

(Debut author, gender-bender harem, 1v1)

Fifteen years have passed since the passage between the two worlds opened. Heroes and evil organizations are now joining forces to fight a new threat.

Mili, a young man with a terminal illness, sees the evil organization's new-tech modifications as his last chance to survive. But doctors from both sides take an interest in him and choose him to wield the Valkyrie Driver, transforming him into a rookie heroine, Valkyrie: Reader. He successfully escapes the terminal illness that had plagued him for over a decade, but...

"So, you're not only an executive in the evil organization, you're also Reader, the girl from the Heroes' Association? When did you go from being my brother to my sister?" Faced with his younger sister's interrogation, Mili had no idea where he'd let his identity slip. She clearly had solid proof, but if he admitted it, then there'd be no way to brush aside the fact that he'd used both identities to beat her up twice when she was a magical girl.

"So..."

"So?"

"When are you bringing that holy sword wielder from the other world home as my sister-in-law? I've been shipping you two for ages."

"You can't force a melon to be sweet. There's nothing between us yet." That follow-up question left Miss Mili even more flustered.

"Then let's settle the score for those two times you beat me up." His sister rubbed her hands together and advanced. Mili instinctively took two steps back, breaking into a cold sweat.

"Don't come any closer! The Valkyrie Driver the doctor made has already turned my body into a complete mess!"
