The player controls Mairu as she meets new people, tries to finish her homework each day, and levels up her conversation topics.

[1][2] The player takes control of Mairu Hibisu, a third-year student at the fictional Cherry Tree High, described as "a lively young girl who just wants to see people happy".

[3] At the start of the game, the player is tasked with recruiting at least three more students to Mairu's comedy club by April 30, or else it will be disbanded.

[5] During the game, the player must develop relationships with each of the six potential recruits, and advance Mairu's standing with them to get at least three of them to join her comedy club.

The player can level up Mairu's skills through means like watching television, reading magazines, or going to public exhibitions.

In cases where they changed the dialogue, they replaced it with Western pop culture references, such as Star Wars and Monty Python, making sure that they weren't "obnoxious or indulgent".
