A Certain Magical Ikamusume-tan

A quasi-official Index/Ika-musume (“Ikadex”) invasion parody has lately  been charming and befuddling fans of both series in equal measure.

The producers apologise for not bothering to include “My little Misaka  imouto can’t be this cute!” material, although the nopan Saten scene  probably makes up for it.
