[Crossover] The Ultimate Double Agent

Blurb:

Otonashi Kiyomi thought nobody could beat her at cheating, until she met Dazai Osamu, who came with his own script.

"Since you're the first person to see through me, I'll give you one chance. I'll grant you one wish."

That bastard answered without hesitation: "Be my dog."

(Deadpan): Get lost.

What could make an underage undercover agent infiltrate four organizations? Tune in to Today's Neon.

The famous undercover agent Otonashi Kiyomi is once again being hunted by various underworld organizations...

A triple agent? A quadruple agent! Every boss thinks Otonashi Kiyomi is truly loyal to them. What a useful pawn.

"So, Otonashi, what would it take to win your heart?"

"Uh... First, it would have to be a secure job."

A few things to note:

1. The pairing hasn't been decided, but it will definitely be settled before the main story ends, and every route will get an epilogue!

2. As the blurb says, yes, the protagonist is on the side of justice... Try to guess which organization she's affiliated with.

3. Her surname is Otonashi. She's Junko Enoshima's older sibling by one year. In this story, Junko is an enhanced version, but she's a twisted brocon. It's a one-sided love-hate relationship, and for now, she has no plans to spread despair to the whole world. For now.

4. Half comedy, half serious drama.

Theme: Don't let outside temptations cloud your judgment.
