 If you liked Prison School |  ...then you might like Grand Blue |
Grand Blue is basically a less raunchy version of Prison School. Both manga share the same comedic style and ridiculous humor; the use of exaggerated and over the top reactions, dialogues, and facial expressions in a wide variety of situations. Yet despite having no similarity in the storyline and setting, the two showcase the male camaraderie and bonds among the cast with a little hint of romance here and there. The art work of both manga also have the similar style and vibe-- clean, proportional, and detailed for the most part. I highly recommend these two especially if you're a comedy manga enthusiast.
- Both are comedies that rely on sexual jokes. - Both take place in a school setting, but are comically over the top. - Both plots frequently deviate from the main character's original goal. i.e: Prison School looked like it would about the boys trying to get girlfriends, only for this objective to be sidetracked very quickly. On the other hand, Grand Blue is more about drinking than diving. - The respective main characters - Iori and Kiyoshi - are similar in appearance and behavior.
Basically same main character, same well-drawn ecchi, same humour, these are really similar. "Prison school's setting is prison while grand blue's is diving, you ****!"

Both manga are ecchi comedies with a lot of sexual humor. So if you are in the mood for a similar comedic style (but a little less nudity but a shit lot of alcohol instead) grand blue ll certainly be the right manga for you.

The most funny mangas I've ever read. Both have really great art to make beautiful funny face lol. If you want to make your day happy, read these, and espescially Grand blue.
Both have the same comedic style, ridiculous humor and exaggerated facial expression in a wide variety of situations. These manga also have a romantic situation and sometimes it will make us laugh because of the dialogues. So if you like comedy manga with a bit of romance, I'm sure you will like both of it.
