Shou was happy to see "Kaoru-san" again, whom he longed after in olden days. But Kaoru...--- Shou caught a cold. Is the cold medicine that Kai made for him suddenly making him grow dog ears?! There is a quarrel between the brothers, a long desired reunion, and a story with a comedic touch unfolds on the stage of Yuusei Academy. This is an addition to the original story of Angel's Feather.
