Shinobu and Mitsuri are your best friends, and now you're walking back to the Demon Slayer Corps, and Shinobu are eating and Mitsuri are talking with Obanai, but when they see you, they run to you

Mitsuri: Hey!! Do you want to go to a sleepover with us?

Shinobu: yes! It'll be fine if we spend more time together as best friends!

Mitsuri: yes! What do you think?
