A Certain Scientific Railgun

After having a bad day, Tsuzuri does a curfew run at an arcade where she meets a boy named Haruki Kōnoe, one of Kazari and Ruiko's classmates. As Tsuzuri's Anti-Skill duties get worse, Yomikawa gives her a day off to finish her teacher work. Later that day, she encounters Kounoe at the arcade and teaches him how to get a secret character in her favorite beat 'em up game, "Gekisho 9". While carrying a drunken Yomikawa home, Komoe gives Tsuzuri a speech about the joys of helping others, inspiring her to do better the next day. After dealing with a mischievous nun, a burger-loving miko, a small earthquake occurs while she tries to help a girl with a missing pendant. Tsuzuri then returns to the arcade, where she ends up playing against Kōnoe on Gekisho 9, both using the secret character. As the two walk home, Kounoe becomes interested when Tsuzuri brings up the idea of another Gekisho sequel, giving his thanks to her when they part ways. Sometime afterward, Tsuzuri learns that Kounoe has transferred to a game-design school, sponsored by Gekisho's creators, which makes her happy to know she inspired him and strengthens her resolve to do better herself.
