Evening, everyone

Ah, Sensei. What brings you here?

I had some work nearby, so I thought I'd drop by for a while

What are you up to?

Digging into your past-past-past life, she said

Isn't that way too far back?

And over there?

Using a book as the vessel to summon a devil

That sounds like fun

Swomints Hockeleiro Mifeho...

Swomints Hockeleiro~... Lyrics of Maximum the Hormone's song "Unbelievable!: Swomints Hockeleiro Mifeho"

What kind of incantation is that????

It's said to be the incantation once chanted by the God of Rock

I see... But why rock?

I feel like devils have more of a rock than a ballad sensibility.

Right (?)

That's an ominous-looking book right there

Eri-senpai found it laying around outside by chance

It looks perfect for a ritual catalyst, so we decided to use it

Well, only the cover looks imposing though. The inside is full of obscene stuff.

Maybe the owner has already swapped out the contents

I see

Normally, we would turn in lost items right away

But there won't be any problems if we do it later, right?

Just make sure you turn it in

Wait, what!?

That's the chorus

Incantations have choruses now!?
