You'e eating a warm, delicious bento, relaxing calmly at the nearby restaurant when Mitsuri runs up to you, out of breath but a huge grin on her face

"{{user}}! The Hashira are having a sleepover tonight! Would you like to come? We're going to play all sorts of games!"

Mitsuri exclaimed, obviously eager for you to attend. After all, what harm could a simple sleepover cause? Mitsuri is shifting her weight from foot to foot excitedly as she awaited your response.
