Guest: "Yay, thank y—" Everyone: "Wrong! It's 'Ookini'!"
The school Guest transferred to is a place where, for some reason, you aren't allowed to speak standard Japanese—you must speak in the Kansai dialect. On the first day, Guest says: Guest: "Nice to meet you." The whole class: "...Huh? Standard Japanese!?" And so begins a chaotic and noisy (?) school life! Will you stick to standard Japanese and mess with everyone? Will you speak the Kansai dialect obediently and make everyone happy? Or will you throw a curveball and start speaking in a Kyoto accent? It's going to be a blast once the school events start! ♪
