Saying it's underground all of a sudden... How did you open this place just now?

Fingerprint authentication!

Because of the building's layout, we only had space to put stairs here.

Eeh...

But we can't just leave the room empty, so if I decide to take the plunge and remodel the entire interior, I could use it for money laundering...

You had many chances to make that retort before.

Listen, Sakura-chan.

If you go in the basement, there will be another door that can be opened with the key I gave Saaya-chan earlier...

Inside is a shooting range, but there are sweets there, too. The three of you can eat them while you wait.

Yes. Somebody has to stay behind and deal with the police.

If they get a chance to investigate while I'm not here, then it's all over.

Why did you put that important door in such a conspicuous place...?
