Kyoukai no Kanata

Synopsis

Mirai starts bringing bonsai to the Literary Club meetings and Akihito deduces her gardening hobby to be the true culprit behind her constant financial problems. Having gotten her license back, Mirai gets information from Ayaka about a valuable fruit-type youmu that lurks on their school roof and Mirai immediately runs off without waiting for Ayaka to explain its characteristics. Afterwards, Akihito arrives too late to stop Mirai from confronting the youmu and both become drenched in a yellow noxious-smelling liquid as part of the youmu's defense. That evening, Ai explains that the youmu gets easily distracted by human girls and thus a two-person team would be needed to defeat it, hence Akihito and Mirai pressure Mitsuki into helping. The following day, Mirai showcases some seductive poses in front of the youmu while Mitsuki approaches from behind, however that plan quickly fails and the youmu marks Mitsuki in a much more horrendous pink liquid. As the group contemplates giving up, Hiroomi explains that the last time the youmu was killed, a special song was used to distract it. However, that plan also fails when Mirai turns out to be a terrible singer. As the entire group showers again that day, everyone decides to seek revenge against the youmu for constantly giving them a horrible stink, and hence spend the next week practicing the words and dancechoreography for the song. Akihito, Mirai, Mitsuki, Hiroomi and Ai then show off the results of their training and perform the song perfectly in front of the youmu and lowering its guard. When the performance ends however, the group horrifically realize their failure of assigning someone to kill the youmu—at which point it explodes and covers the entire roof in a torrent of yellow liquid. (Source: Wikipedia)
