What is with this chair...!

Hmm? What is it?

It's fixed on the ground, and I can't move it!

Hey! It's big sister Illustrious!

Oh, it's Javelin and Juno, are you dining in mess hall?

Yeah, you too? Big sister Illustrious?

Well, um, I'm not. I don't usually dine in mess hall.

Because...

I can't move my chair backward.

Huh? Just for an unmovable chair?

I came here last time with Sirius...

Because the chair is fixed to the ground and cannot be moved backward, we ended up having absolutely no room to put our... stuff... s-so...

Ahahahaha
