From Irodori Comics Lite:

One day, Sayaka finds a banana on the street, which is summarily consumed by a loitering Yoshiko. Later that night, Sayaka is visited by the spirit of the banana, who transforms her into an angel and tasks her to go help souls in need. She eventually winds up at A-kun's house, where she now has to grant his true heart's desire... to marry Sayaka? Find out just what on earth is going on in this parody spin-off to Hiroyuki's wildly popular Aho Girl series!
