The genre of this game is similar to a deck-building rogue game.
Hina-chan's mobile device is broken and she can no longer use the text input and microphone functions. The game is a game in which Hina-chan has to use only stamps in order to respond to chats from Nitori, Suika, Joon, and others. Hina-chan responds to these chats with a stamp, and manages to chat without being suspicious.
