Fashion model and tarento Tenka Hashimoto will star in a live-action adaptation of Mari Matsuzawa’s quirky incest-themed manga Saikin, Imouto no Yousu ga Chotto Okashiin Da Ga (literally “Lately, my little sister’s been acting a bit strange, but…”), aka “ImoCho” for short. The role will require both her and gravure idol Mayu to appear fully nude for the first time.
Hashimoto, often credited separately as “Tenchim”, first made a name for herself as a child actor by making regular appearances on NHK’s Tensai TV-kun MAX. Since then, she’s had success as a charisma model with a hugely popular Ameba blog which has reached over 200,000 hits per day.
She plays Mitsuki, a high school girl whose mother recently remarried only to move away with her new husband, leaving Mitsuki behind to live with her new stepbrother Yuuya. One day, she’s possessed by the spirit of a girl named Hiyori and discovers she’s been fitted with a strange magical chastity belt. Hiyori claims to be a ghost and remembers nothing of her former life other than being in love with Yuuya. As Hiyori’s love for Yuuya is the only thing keeping her tethered to the living world, she decides to use Mitsuki’s body to help her reach the “Gates of Heaven”.
Mitsuki’s chastity belt is equipped with special “TST” (teisoutai = chastity belt in Japanese) satisfaction meter which goes up each time she engages in ecchi acts with Yuuya. Each time it’s filled, a new stair is built in the afterlife for Hiyori’s ascension. However, if Mitsuki refuses, she’ll be trapped in the chastity belt forever.
The film marks the directorial debut of photographer Yuki Aoyama, whose popular fetish photo collection Schoolgirl Complex was adapted to a film released over the summer.
“Imouto no Yousu ga Chotto Okashiin Da Ga” will be released in Japan in spring 2014.
