PlotEditKakyoin wakes up one morning to discover that he had "laid" an egg and reveals it to his friends. When his friends discover this, Joseph asks when his grandson will be born (thus turning Jotaro and Kakyoin canon for this doujinshi).
The child suddenly hatches out of the egg to reveal a star-shaped birthmark on his shoulder. Thus concluding that Jotaro and Kakyoin produced an egg. Out of courtesy for Joseph Joestar, they name the small boy who hatched out the egg Jouta. The child, it would appear grows faster than a normal human and within a week he is able to attend school.
In a jealous fit, Jotaro attempts to fight Jouta. Jouta suddenly activates his stand, which looks like a more "chibi" version of a green Star Platinum. Polnareff comes up with an idea to have Jotaro name Jouta's stand because he was "too lazy" to do it himself. In annoyance, Jotaro walks over to the kitchen to bring out green dish soap, saying the name of the brand, "Charmy Green".
