Location: House of Lamentation / Dining Room

Barbatos: ...And that brings the lesson to a close.

Belphegor: ...After how long?

Asmodeus: Five hours and...how many minutes?

Satan: It's time for a nap...

Barbatos: Beelzebub, Leviathan.

Leviathan: W-What?

Beelzebub: Can we take care of this after I get something to eat?

Barbatos: Do you remember the test held during the lesson? Your scores were less than favorable.

Which means you two get to repeat the lesson here with me.

Leviathan: Just us two? What about Mammon?

Barbatos: Surprisingly enough, Mammon put on a better show than either of you.

✧

He definitely cheated!

Leviathan: Yep, there's no other way.

I feel bad for you two.

Beelzebub: Itsuki...

Barbatos: I will not allow you two to waste any more time.

Leviathan: Demon...!

Barbatos: Shall we begin?

When setting the table, which side of the wine glass do you place the water glass?

Leviathan: Uh, let's see...the left side?

Beelzebub: I thought it was the right side.

Barbatos: MC, do you know?

✧

The left side.

Barbatos: Correct. The left side.

The right side.

Barbatos: Incorrect. It's the left side.

Um...

Barbatos: The left side.

✧

Barbatos: How do you two expect to become competent butlers when you cannot even agree on something as elementary as this?

Next is napkin folding and its many variations.

Leviathan: We're not done yet?

Beelzebub: When do we eat?
