After the capture, Hajime was worried about the farewell to Myuu that would occur when the trip resumed.
Hajime and his friends were talking about "The Seven Great Legends of Erisen" as a memory before they left for the trip, but all of them were missed.
However, in the final seventh adventure, he encounters a mysterious giant creature and is blown into the world of a devastated city!
Hajime, who started to search for the stray Myuu, fulfills a miraculous encounter there.
