Six months has passed since the end of the first run of Index (Prior to Kurimu, my waifu =3) and also a year since Index has started airing. Well instead of a second season (which I highly demand) here’s a spin off anime series based of a spin off manga, To Aru Kagaku no Railgun, ie. A Certain Scientific Railgun. Featuring that pesky tsundere-like Biribiri.
