Good Day for Gag Manga

Hirata came to a realization that he is only a manga character in a barren world, he hopes for a rival to appear like in typical Shōnen manga, and he was granted one - wearing panties on his head.

The second part continues Usami-chan's adventures in solving more perverted cases in the school.
