Recently, My Sister is Unusual Live Action Blu-ray is directed by Yuki Aoyama.

New house?! New school?! New family?! Mitsuki Kanzaki has a lot on her plate recently. Things get even messier when she’s suddenly possessed by Hiyori—a salacious spirit with the hots for Mitsuki’s new stepbrother. Unfortunately, this ghost isn’t easily exorcized away as Mitsuki has been cursed with a spectral chastity belt and is tasked with helping Hiyori ascend to the next plane of existence. To do that, Hiyori needs Mitsuki to get uncomfortably close to her stepbrother... or they’re both six feet under.
