In Florida, 2011, Jolyne Cujoh 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 course to stop their plot, clear her name, and take back her life. [Written by MAL Rewrite]

The sky is the limit in Houkago no Pleiades. With telescope in hand, Subaru is set to go to the observation room of her school in order to get a view of that night's meteor shower. What she least expects is that behind the observatory door was not the starry skies, but a lavish garden, complete with a resplendent fountain and a mysterious young boy with long red hair. But the garden soon disappeared, as if Subaru was only imagining things. All that remains of that brilliant sight is an odd, bouncing blob creature that leads her to another magical door, occupied by other girls in magical witch-like costumes. Revelations start hitting Subaru one after the other: one of the girls in the room is her childhood friend Aoi, the little blob is actually an alien of a species called the Pleiadians trying to return home, and Subaru has been selected by him to become the newest member of their group! Now Subaru's dreams of the stars have come true in the wildest way, as she and her friends attempt to gather pieces of the Pleiadian spacecraft engine to return the being to his home. But they're not the only ones after the engine parts, and they have no idea why!

The story follows Benio "Haikara-san" Hanamura, who lost her mother when she was very young and has been raised by her father, a high-ranking official in the Japanese army. As a result, she has grown into a tomboy. Contrary to traditional Japanese notions of femininity, she studies kendo, drinks sake, dresses in often outlandish-looking Western fashions instead of the traditional kimono, and is not as interested in housework as she is in literature. She also rejects the idea of arranged marriages and believes in a woman's right to a career and to marry for love. (Source: ANN)
