[Crossover] A True Spirit's Daily Life as an Undercover Agent

(Next door: The Undercover Agent's Real Booze. It's part of the same series. That story focuses mainly on comedy bits, while this one focuses on the main plot.)

A bottle of real booze is the protagonist of this story.

At least for now, he's exactly what his name suggests: a real bottle of booze.

He's an ordinary intelligence agent, though being his colleague comes with a debuff that makes your identity easier to expose.

One day, he received an assignment:

"Go undercover in the Port Mafia! - by Irish"

Then he received another assignment:

"Go undercover in the Black Organization! - by Mori Ogai"

When the fake is mistaken for the real, even the real can become fake. Keep up the act long enough, and the fake will become real.

But in the end, which side is fake, and which is real?

P.S.

1. The author is a Mori fan, so there may be a lot of praise for Mori that I don't even realize I'm writing. If you notice it, please don't point it out.

2. The pairing is undecided, and it may well have no romance. The protagonist will become a Mori fan, so proceed with caution if that bothers you.

3. The protagonist is firmly committed to a science-based worldview. Everything can be explained by science, and it's hard to say who will end up tormenting whom.

4. The protagonist goes undercover in the Port Mafia as a real bottle of booze. Later, the organization might be absorbed, leaving him with a side job that becomes his only job, or the organization might be destroyed and he'll lose his job before the Port Mafia takes him in. Anything could happen. Proceed with caution if that bothers you.

5. As always, updates will come whenever they come. _(:з"∠)_
