Laughter! Vol.Z

'''Laughter! Vol.Z''' is the debut chapter of Mazinger Otome, introducing most of the main cast.

Summary
Seto Magami is watching the Mazinger Z TV show but her excitement causes her to break the TV with her own Rocket Punch which irritates her 'cousin' Koji Magami. After a brief introduction involving Seto, Koji, and their grandfather Juzo Magami, Seto and Koji head to school with Seto explaining the limiter signs while encountering her schoolmate Shiko Kotetsu, a cyborg with even the slightest touch causing her to fall apart. At the school, the Mechanical Beast Army came for a fight which Seto accepted. During the battle, she is helped by her 'older sister' Reito Magami who insists on her technicality of being the newer model. With the Mechanical Beast Army getting irritated, Seto finishes them off with her Breast Fire which burns her top off.
