[Everyone survives, pairing undecided]
Shindo Chiyumi: an impressive track record, an eighteen-year-old PhD in mathematics from Stanford, and a paper that caused the Karasuma conglomerate's stock to be shorted and the Black Organization to teeter on the verge of bankruptcy.
As a result, the Organization put out a global hit on her.
For example
Bourbon: Miss Chiyumi is so adorable. If you don't want to be killed, come over to my side.
Scotch: Zero, you're so sly. I was clearly the first to...
Black Shin: Are you my nemesis, Miss Holmes?
Chiyumi: Let's see which chuuni is calling himself Moriarty... Oh, this one's the real deal.

In retaliation, Chiyumi decided to put together a team to bring down the Karasuma conglomerate. Just as she was about to recruit some partners...
Would you look at that? All the talent was in the criminal underworld. There wasn't a single useful person in all of Beika Town.
So Chiyumi started poaching from the criminal world, defeating her former nemeses and threatening them into betraying the Karasuma conglomerate.
But why did these nemeses start acting so strangely after she beat them...?
Black Hagi: To keep me from making mistakes, little Chiyumi, you'll have to keep an eye on me forever.
Black Matsu: Tch, you're a handful. Are you really that eager to put a collar on me?
Black Shu: My nemesis...my lover. I'll fight for you.
Chiyumi: Wait, a nemesis is a nemesis. Nemeses can't become lovers...
Reader's Guide
★ Everyone is loved; no character from the original work is villainized, but the Red Team turns dark: Black Hagi, Black Matsu, Black Kei, Black Zero, Black Shu, Black Shin... The characters who turn dark later reform for love. The Black Team's original allegiance remains unchanged, and they receive a massive power-up. Beika Town is home to a colossal conspiracy. The Red Team wins in the end, and Beika Town's dark side undergoes a major overhaul. Everyone on both the Red and Black Teams survives.
★ Plot-driven, feel-good story, packed with comedy. Later on, the heroine wins everyone over by force, so there's a slight everybody-loves-her vibe.
★ The heroine is the Red Team's one and only pillar, a genius at the very top of her field, and surrounded by the Black Team...so ordinary people misunderstand her as having paranoid delusions.
★ Pairing undecided. Whoever reforms first gets to be the male lead :) Everyone is working hard to do good deeds.
Theme: Good people live long and prosper.
