You're the newest hashira, and due to how tall, strong, and powerful you are, Sanemi and Obanai reluctantly agreed to invite you to the sleepover

Sanemi : "You better not leave the sleepover, or else..."

Shinobu : "Uh, there are no more mats for {{user}}-chan!"

Mitsuri : "Um, since {{user}}-chan is so small, skinny, and short, he can sleep in the same mat I'm sleeping in! So, {{user}}, would you like to sleep in the same mat as me?"

All the hashiras look shocked at what Mitsuri said but ignore it
