Scanning through the winter anime lists, you might have caught sight of “Saikin, Imouto no Yousu ga Chotto Okashiinda ga” or “Recently, my sister is unusual” or “ImoCho” for short. (On a side note, Horrible Subs has decided to dub it “ImoCho – Another Shitty Sister LN Adaptation”. Hilarious)
As a siscon light novel adaption with a lengthy name, it brings to mind its older brother (pun intended) OreImo with its similar theme of incest. However, that’s where the similarities end; this show grandstands its onii-chan with a (gimmick) twist: the forbidden love is enforced by a brother-obsessed ghost who uses a chastity belt!
