A Certain Scientific Railgun

Mikoto, Kuroko, Kazari, and Ruiko take action against a gang of bank robbers. When Ruiko is injured trying to rescue an innocent bystander, Mikoto angrily unleashes her railgun power!

Mikoto and Kuroko get in trouble for using their powers in the dorm. Their punishment: pool cleaning duty! Later, Kuroko finds herself feeling frisky after accidentally ingesting a powerful aphrodisiac!

Someone is tasering students and drawing on their faces with permanent marker! While Kuroko and Kazari investigate, poor Ruiko becomes the latest victim. Who is behind the unusual attacks?

Awkwardness ensues when Mikoto runs into Kamijo. When they meet again later in the day, Mikoto demands a duel! She gives it her all, but there’s a chance she’s no match for Kamijo’s powers.

Uiharu and Kuroko have an argument that leads to recollections of the past, when the girls were young Judgment recruits, and a dangerous mission resulted in a life-long promise between friends.

Someone is planting bombs all over Academy City, and it’s up to Judgment to stop the person responsible. Mikoto, wanting a piece of the action, uses Uiharu’s badge to investigate on her own.
