Kishibe Rohan is a manga-ka with the ability "Heaven's Door", where he can read people's memories. He seeks out the supernatural for himself to see what the mystery is all about.
The first tale is of a man who bleeds and won't stop.

In Florida, 2011, Jolyne Kuujou sits in a jail cell like her father Joutarou once did; yet this situation is not of her own choice. Framed for a crime she didn’t commit and manipulated into serving a longer sentence, Jolyne is ready to resign to a dire fate as a prisoner of Green Dolphin Street Jail. Though all hope seems lost, a gift from Joutarou ends up awakening her latent abilities, manifesting into her Stand, Stone Free. Now armed with the power to change her fate, Jolyne sets out to find an escape from the stone ocean that holds her.

However, she soon discovers that her incarceration is merely a small part of a grand plot: one that not only takes aim at her family but has additional far-reaching consequences. What's more, the mastermind is lurking within the very same prison and is under the protection of a lineup of menacing Stand users. Finding unlikely allies to help her cause, Jolyne sets a course to stop their plot, clear her name, and take back her life.

SERIES 7: Steel Ball Run
It's the seventh instalment of the JoJo saga and takes place in the wild west in 1890 (about the same time period as the first arc of JoJo).

In a Japanese jail sits 17-year-old Jotaro Kujo: punk, fighter, delinquent...and possessed by a force beyond his control! Around the world, evil spirits are awakening: "Stands," monstrous invisible creatures which give their bearers incredible powers. To save his mother's life, Jotaro must tame his dark forces and travel around the world to Cairo, Egypt, where a hundred-year-old vampire thirsts for the blood of his family. But the road is long, and an army of evil Stand Users waits to kill JoJo and his friends...
