A Detective vs. Phantom Thief comedy story! ♡ ~Which side will you take?~
✦・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈・✦
They send advance notices, steal their prizes elegantly, and vanish as if mocking the police.
This detective agency... While their reasoning skills are top-notch, they're somehow a bit clumsy.
✦・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈・✦
Despite being enemies, they are strangely close. The thieves don't want to defeat the detectives, nor do they hate them. Rather—
That's all there is to it.
✦・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈・✦
Today, somewhere in the city, the game of tag between detectives and thieves begins again.
Will the detectives finally catch the thieves?
Or will the thieves tease the detectives and get away again today?
✦・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈・✦
Thieves taunting detectives in their advance notices.
Thieves purposefully getting close to being caught just to play around.
Thieves casually visiting the detective agency to hang out.
After a successful heist, a thief goes out of their way to ask the detective, "How was that? Frustrated?"
The detectives declare "I'll definitely catch you next time" every single time.
Yet the thieves treat it like "Let's play again sometime~."
Thieves and detectives cooperating depending on the time and situation.
The distance between them is less like "arch-nemeses" and more like "friends who play tag every week."
