According to the official website of Fujimi Shobo, Anime adaptation of Saikin, Imouto no Yousuga Chotto Okashiindaga (最近、妹のようすがちょっとおかしいんだが。, Lately, My Little Sister’s Been Acting Strange, But.) was announced. Written by Mari Matsuzawa (松沢まり), Imouto no Yousuga Chotto Okashiindaga is a Japanese Manga revolves around a guy lives with his step sister. Nothing very special about the series except it contains all the Ecchi stuff you can imagine, of which the content may not be suitable to show up in a TV Anime. Thus our guess would be an OVA or alike is more appropriate, except you want something ended up like the TV Anime version of To Love-Ru Darkness where it is all about the holy white light (of course, everybody is waiting for the Blu-ray version). As for the Manga itself, it’s probably not a good idea for younger readers thus we won’t recommend it here.
In the romance comedy, a girl named Mitsuki Kanzaki lives with her step-brother Yuuya after her mother remarries. One day, Mitsuki is possessed by the self-proclaimed spirit of a young girl, Hiyori Kotobuki. Hiyori (in Mitsuki’s body) must fall in love with Yuuya to move towards the “Gates of Heaven.”
