Keitaro’s entrance‑exam day has arrived, and he hopes to succeed. However, in the final stretch he fails miserably and becomes lost in daydreams. Assuming he has failed, he runs away, prompting the rest of the cast to hunt him down on a remote desert island. The Toudai University entrance exams have come again for Keitaro. Confident, he sits for the paper but falls asleep, dreaming of Narusegawa. When he wakes, barely enough time remains to finish the test, and he fears failure. In an attempt to escape from Hinata Lodge and erase the memories, he encounters Seta, but finds himself on a faraway island with the whole cast searching for him.
