Special series from Toaru Kagaku no Railgun, short humor story compiled to 8-9 minutes episode sometime refresh up the memories of watching their TV series before… rumors said it will be 4 special episode, others says it’s still unknown, on Wikipedia they write 4 title but the digit of 13’ still wondering me what they mean. They make me become more curiously to know the actual, or maybe this feeling occur when I finished my Anime collection database just after last evening and in process to empty my hard disc. Space rules in hard disc and all in high quality. Hear up they will aired Toaru Kagaku no Railgun OVA’s around end of this October.
Hope someone can tell the exact number of special series.
