Oda Sara, an orphan who grew up in the Slum, was sent to a world without supernatural powers by an explosion. Though her naturally red hair made people treat her as an outsider, she still worked hard, passed the professional civil service exam, and became the Bomb Disposal Unit's youngest assistant police inspector.
On her first day at work, her superior informed her that Matsuda Jinpei, the Bomb Disposal Unit's ace, who had originally been assigned to her team, had requested a transfer to the First Investigation Division.
During her first week, she dragged her truant subordinate out of a Ferris wheel packed with bombs and docked a week's pay.
In her first month, she found a gorgeous man with catlike eyes on a rooftop. Then he “lost his memory.”
Oda Sara has a secret: her supernatural ability has developed a will of its own and become a “Bomb Disposal System.” Wherever there's a bomb, Oda Sara will be there.
The more bombs she disarms, the faster the System levels up and the farther it can search. Once she gets it to the highest level, she can return to her own world.
Oda Sara really wants to return to her own world, because she's always wanted to find her biological older brother, who went missing when they were young.
Unfortunately, Oda Sara has maxed-out combat skills and theoretical knowledge, but zero practical experience. She only managed to join the Bomb Disposal Unit because the System cheated for her.
So she sets her sights on her subordinate, Matsuda Jinpei. He may be a bit sharp-tongued, but as long as he can disarm bombs, that's all that matters.
Oda Sara and Matsuda Jinpei begin a systematic sweep to clear out bombs, but every time, something unexpected happens.
There's a bomb on the cruise ship!
Conan is solving the case, Ran is trapped, the story has reached its climax, and the bomb goes off... No, it doesn't?
Two people crawl out of the cargo hold, stinking of fish. “Who planted the bomb? Of all the places to hide it, you picked a pile of dead fish? Ugh!”
The Ferris wheel is about to explode again!
A thrilling showdown takes place on the Ferris wheel, while beneath it, someone works hard to defuse the bomb.
Oda Sara: “Don't let me find out who planted that bomb! I only finished cleaning up this area yesterday!”
Matsuda Jinpei: “Shut up and work! I'm the one who defuses all the bombs. What have you worked hard at?”
Amuro Toru: “I didn't plant it, so leave me out of this!”
To stop bombs at the source, Oda Sara sets her sights on the biggest supplier, the Black Organization, and plans to take them all down. What a brazen organization. They've planted bombs beneath every base. Boss, aren't you afraid to sleep on top of a bomb?
P.S. The heroine is Oda Sakunosuke's younger sister. She's the strongest fighter around, has perfect theoretical knowledge of bomb disposal, and zero practical skill. She has a System that displays bomb locations on a map.
Couple: Matsuda Jinpei
