Toaru Majutsu no Index? Toaru Sangatsu no Zouyo Koukan & Toaru Sangatsu no Ni Rei Ichikan (とある魔術の禁書目録?とある三月の贈与交換&とある三月の二〇一巻), abbreviated here as Toaru Sangatsu no Zouyo Koukan & Toaru Sangatsu no Ni Rei Ichikan (とある三月の贈与交換&とある三月の二〇一巻) due to formatting reasons is a collection of two parody short stories based in the Toaru Majutsu no Index universe written by Kamachi Kazuma.

One of the more obscure short stories written in the universe by Kamachi, it was released on the Dengeki BUNKOYOMI edition of the now defunct Dengeki hp magazine in March 2006, with Otani Osamu as the parody illustrator.

Toaru Sangatsu no Zouyo Koukan
Toaru Sangatsu no Zouyo Koukan (とある三月の贈与交換), translated as A Certain March Gift Exchange, is a short story revolving around Touma's ordeals on White Day.

Summary
Kamijou Touma is living his everyday life when all the girls around him suddenly ask him to return the favor from Valentine's Day, but he has no memory of receiving anything. It turns out he assumed he would never get any chocolate on Valentine's so he drowned his depression in alcohol. He got so drunk he lost all memory of February 14, but he had drunkenly gone all around the world and caused tens of thousands of girls to fall in love with him in the process. Touma laments his misfortune as these unremembered actions cause him to be chased around.
