Original Sin: I Refuse to Be Conquered by My Little Sister After Turning into a Witch

[Genderbend Yuri] + [Won Over by Her Younger Sister] + [1v1] + [Demon Cards] + [Seven Deadly Sins Witches] + [Hilarious Familiar]

Familiar Mingke: Become a witch!

Han Linyu (dazed): Wait, I'm a guy. How am I supposed to become a witch?

Familiar Mingke (smiling meaningfully): Why don't you take another look down there?

Han Linyu (looking at her unbelievably beautiful body): What the *#&￥

Humans, witches, creatures of sin... This is an extremely dangerous world. More than anything, Han Linyu wants to protect her younger sister. To do that, she is willing to hide her identity and grow stronger.

Soon...

Mu Yuling (looking at the girl with a smile): You really made me work to find you, my adorable... big brother.

As her younger sister kept approaching, Han Linyu cowered in the corner, tears of fear welling in her eyes. She shouted, “No, Yuling, please, no!”
