I May Be Holding a Deadly Weapon, But I'm Really a Good Person!

Momozawa Yukina was reborn one day and discovered that she had landed on the set of a detective story.

Though murders and robberies happened here from time to time, she was incredibly excited.

Was there anything more delightful than having her favorite fictional characters right in front of her?

So she studied like crazy, passed the civil service exam for career-track police officers, and enrolled in the police academy.

[Ding! Congratulations, Host! You have become the lucky one in this world!]

The day before school started, a voice appeared in her mind.

Here it comes, here it comes! The golden finger she had been waiting for over twenty years had finally arrived.

Yukina: I know you're here to help me become the greatest police officer, right?

[Congratulations, Host! You have successfully bound the Crime System! With the System's help, become a notorious criminal!]

Yukina: ?

[Congratulations! You have received: Blades (Mastery), Firearms (Mastery), and the skill 'Master Thief' (Max).]

Yukina: ???

What? What is this?!

On her first day of school, Yukina spotted the tousle-haired Matsuda walking slowly ahead. She excitedly rushed over, ready to say, "Hey, honey!"

Right before Matsuda Jinpei's astonished eyes, a sharp dagger fell out of Yukina's pocket.

Matsuda: You came rushing over so excitedly because you wanted to kill me?!

Yukina's eyes widened in shock as she hurriedly shook her head. "No, it's not like that! Let me explain!"

[How can you be a notorious criminal without carrying a weapon at all times?!]

Thanks a lot!

One day, Yukina was eating at a restaurant with the five members of the police academy group. When she got up to go to the restroom, she brushed past a man.

[Skill 'Master Thief' Max activated, ]

Yukina: Hm? It feels like there's something extra in my pocket...

The man returned to his table to start his crime, but when he reached into his pocket, it was empty. As he frantically searched himself from head to toe, Yukina quietly tapped him on the shoulder.

"Maybe you're looking for this?" Yukina said apologetically, handing him a bottle labeled potassium cyanide.

Man: So which one of us is the murderer here, you or me?!

One day, Gin was on a mission carrying a briefcase when he brushed past Yukina.

Yukina: (panicking) (remembering she was a police officer) (looking at her skills) (feeling confident)

"Hey!"

Yukina shouted and lunged at him. Just as she tripped over her own feet and nearly fell, something else appeared in her hand.

[Skill 'Master Thief' Max activated, ]

Yukina stood there holding a man's belt, staring at Gin.

Yukina: Listen, let me explain! It's not what you think, bro!

At a jewelry exhibition, Kaito Kid sent a calling card announcing that he would steal the most expensive gem.

Yukina was among those assigned to protect the jewelry, but Kaito Kid still stole the gem without anyone noticing.

While everyone was in a panic, she brushed past someone...

[Skill 'Master Thief' Max activated, ]

Suddenly, something extra was in her pocket. When she pulled it out, it turned out to be the very gem everyone was searching for!

Kid: ...Are you the phantom thief, or am I?

She successfully completed her mission to protect the jewelry and, for the first time, beat Kaito Kid. Her superior was thrilled, and she got to bask in the glory.

Now all that awaited her was a promotion, a raise, the peak of success, and a thank-you bonus from a wealthy benefactor!

Yukina: She knew her dumb-as-a-rock System was good for something. Thank you, thank you, everyone!

System: ...

Her skills might not seem all that reliable, but they were pretty useful in practice.

Firearms Mastery earned her perfect scores on every shooting exam, while Combat Mastery made her a legend who could beat anyone at school.

It was just the Master Thief skill, which activated on its own from time to time, that gave her a headache.

Rei Furuya had Yukina cornered against a wall, and she stammered as she tried to explain why she was holding his men's underwear.

You have to admit, the Master Thief skill let her experience what it was like to be chased!

Yukina clutched Matsuda Jinpei's phone and ran for her life, close to tears.
