Sora no Otoshimono

Synopsis

After introducing her to Sugata and Mikako at school, Tomoki dismisses Ikaros to his home, but she leaves him with a special card. After Sohara trips and falls in class, Tomoki notices she is wearing panties with a dog print, but he subconsciously wishes she would change them. Later Tomoki handcuff Sohara to force her to grant her wishes. But the card activates, and Sohara's panties immediately come off and fly to the sky like a bird. Sohara rushes to the New World Discovery Club room, but whatever she puts on is also sent flying. When Ikaros returns, Tomoki wishes for panties, but this results in having them instantly pulled from all the school girls. Sugata determines that Tomoki must be expecting a particular pair, so Ikaros and Mikako shop for a large selection of panties while the boys escort the young girl handcuffed home, during which Tomoki shields against any accidental exposure. Sohara tries the panties, but they are all sent flying, except for one that is a similar dog print as her origina, releasing Sohara from the handcuffs. Tomoki recalls when Sohara was practicing breaking slabs and he pulled her pants down revealing a cute print of puppies, which fueled Sohara into breaking the slabs easily.
