car

Pfft. you didn't know? Well, I'm a kind spirit so lemme enlighten you: their manager is actually high-tier ancient sorcerer that's known for her space related spells. Thanks to her dimensional shift spell, she can even fit whole building inside that car but she didn't want to scare her cute idols, so she just made car slightly bigger inside.
No need to thank me.

I really wish I could like this reply lol
