Sora no Otoshimono Forte

Synopsis

For this year's festival at the Satsukitane shrine, Mikako holds a "yo-yo" fishing contest where all the girls are tied up in a pool, and the guys tied on ropes must grab them out of the water. The winner is whoever can catch the fish with the biggest "yo-yos". Tomoki transforms into Tomoko for this competition, teaming up with Sugata, while Mikako partners up with Judas. Tomoko manages to snatch some of the girls until Sugata baits the buxom Astraea with some snacks, but Mikako steals the catch. Sugata then brings up the "legendary fish", one whose measurements are still growing. Tomoko transforms back to Tomoki and finds the legendary fish only to be knocked out by her karate chop. Ikaros receives a farewell letter where Tomoki proposes to her. Tomoki clarifies by giving Ikaros and Nymph an allowance. After hearing from friends on different gift suggestions for Tomoki, Ikaros decides to follow Sugata's advice, and buys herself a watermelon, after which Tomoki affirms she did good.
