Konoha's Medical Ninja: One Punch to beat up Madara - Chapter 390 - : Oden? Yamato?

10 years ago, after “the Gate” that connected the real world with the monster world opened, some of the ordinary, everyday people received the power to hunt monsters within the Gate. They are known as “Hunters”.

In a world where strength reigns supreme and only the strong are revered, conflict and injuries are commonplace.

Upon meeting the girl who would become her adopted younger sister, the duke’s daughter Christina regained memories of her previous life. Through those memories, she learned that her new sister, Mishuli, was the heroine of a certain story. And though the story depicted a Christina who abused her sister, the real Christina turned into a siscon who spoiled Mishuli to no end.

It’s the vacation of a lifetime, a trip to a remote island filled with geniuses and murder.
