A Certain Scientific Railgun Season 1 Episode 18

Cypress Park

After incurring her wrath the previous night, Mikoto and Kuroko spot the dorm supervisor walking about. They follow her to an orphanage where they are surprised to see a kindhearted dorm supervisor be friendly to the kids. Mikoto and Kuroko also spot Ruiko and Kazari helping out, and they notice the dorm supervisor appears to have feelings for their teacher, Daigo. Hoping it would change her attitude in the dorm, Kuroko offers to play cupid and get the two together. Whilst the gang help out with the kids the next day, the dorm supervisor and Daigo work together to make a cake, though she has a bit of trouble staying focused. As Mikoto plays with the kids, she is reminded of Harumi's memories. Just then, an earthquake kicks in and the dorm supervisor rushes to protect one of the kids, getting praise from Daigo. The two later go to dinner, where Daigo brings up the topic of marriage. However, a few days later, Daigo reveals he's planning to propose to one of the other helpers, and the dorm supervisor quickly reverts to her usual ways.
