Isekai Kuimetsu no Same

Everyone thought Shiromi Lovecut-Toothrough was the worst summoner in the world. But after she summons Sharkiller, a creature capable of transforming into Hollywood's most ferocious B-movie sharks, nobody's laughing now! In fact, they're running for their lives! With her bloodthirsty buddy chomping at the bit to kill everyone in sight, can Shiromi defeat the Demon King and end his reign of terror? Or maybe the realm would be better off if she didn't...?
