Flonne had an important mission to accomplish.

Requested by Seraph Lamington himself, Flonne was tasked to kill the Overlord of the Netherworld. Which, while something she had some qualms with, was an order from the Seraph. And given how wise and kind and cool and awesome he was, the angel trainee had faith that her mission was for the greater good.

She hadn't expected the Netherworld to seem so... high-tech and narrow?

Wandering the corridors of the Netherworld(?), the blue-ribboned angel stared in wonder and intrigue. Was the Netherworld really like this? Wasn't this more... Earth-like? Futuristic? She thought the demons were supposed to be brutes, not scientists!
The corridor she traversed finally opened into a more open area, and Flonne spotted a girl writing a whole stack of papers. Judging by her expression, it was not the most fun activity. Maybe it was homework?

"...Hi there!" Flonne announced her presence cheerfully to the demon(?). She would have been more cautious normally, but... actually no, Flonne wouldn't have used caution regardless. Brute or not, love would prevent a conflict! "Um, I'm looking for King Krichevskoy's lair. Would you happen to know where it is? I assume it's, like, a giant castle, but I dunno what corridor it's in!"

The implications of an angel managing to mistake an entire dimension for a interdimensional ship in orbit were quite staggering for those observant.
