Sora no Otoshimono

Tomoki and Sugata return Chaos to Daedalus. Things return to normal, with Nymph restoring Ikaros's memories, and Tomoko later teaches Ikaros bathroom etiquette. However, Tomoki has one more perverted task, which is to transform into pool water so he can fondle girls during swim class. After Sohara and Nymph drain the pool, Mikako decides he needs to be taught a lesson. Tomoko escapes the hunt by hiding in the girls' bathroom, but is eventually trapped. While Sohara saws down the door lock, Tomoko has no choice but to escape into the toilet and go through sewage treatment to the sea. Later on, Ikaros, in trying to practice bathroom etiquette of knocking and flushing, knocks a hole in the door and flushes Tomoki again. As Ikaros searches for Tomoki, Mikako sees her and offers to help with her proposal situation. A flushed out Tomoki is taken to a wedding chapel. With Sugata and Mikako presiding, Ikaros appears dressed in a bridal gown. She and Tomoki go through a wedding ceremony, but when they are about to kiss, Tomoki stops. Mikako then gives him a choice: he can pick Ikaros, Nymph, Astraea, or Sohara, all of whom are dressed as brides. Tomoki screams at the indecision, but the ceremony is interrupted by a reformed Chaos, who gives Tomoki a hug, and becomes the newest resident Angeloid.
