Hime Chan's Ribbon
Transformation into the Senpai I Admire (1x3)
:
Hime-chan realizes that Hasekura must be thinking that he confessed his love to her sister Aiko for real the day before! Also it must have been a shock to him to see Aiko running away. Daichi comes by and does what Hime-chan asked him to do, try to pick up Aiko, so Himeko (transformed into Hasekura) could heroically save her, and make a new confession to the real Aiko on senpai's behalf.
