"勘違いくん キャラクターガチャ" is a free iPhone game developed by Shinichi Shimada. The game revolves around pulling gacha to collect cards, with a single ticket allowing one gacha pull. Players can enjoy a guaranteed SR or higher card in a 10-card pull.

With over 150 different cards available, featuring popular characters like Natsuki, Yuna, Mami, Takumi, and Aoi from the "勘違いくん" series, players can aim to gather their favorite characters in card form.

Players can earn tickets by watching in-app videos, which can then be used to spin the gacha. Cards come in four rarities - "N," "R," "SR," and "SSR." SSR cards allow for image downloads, which can be set as wallpapers on smartphones. Moreover, both SSR and SR cards support voice playback for an enhanced gaming experience.
