Mysterious space turtles make a big fuss at the underground secret base

Bellabo, who Ichiro Urashima rescued, was a mysterious space turtle that flew in the sky with its face swollen. While chasing it, I arrived at a super high-tech secret base that spreads underground. This is the first time that "Berabo", which was serialized in "Manga King" from 1968 to 1969, has been collected in one book! It is the definitive edition for core fans. (Commentary by Hideo Shinoda)
