(A safety engineer transmigrates + System + Fanfiction)
After transmigrating into Demon Slayer, Lin An has no Breathing Style and no strong physique.
But he awakens the [Work Safety Supervision System]!
From then on, the Demon Slayer Corps takes a completely different direction.
Tanjiro uses Water Breathing!
[Warning: Humidity in the work area exceeds safe limits. Slip hazard detected. Work forcibly halted!]
Zenitsu uses Thunder Breathing!
[Warning: Instantaneous voltage is too high. Risk of electric shock detected. Power forcibly cut!]
The Flame Hashira unleashes his ultimate move!
[Warning: Large-scale open-flame work detected. No hot-work permit filed. Fire forcibly extinguished!]
The Demon King Muzan splits himself apart!
[Warning: Illegal biological cloning experiment detected. Violates ethical standards. Clones forcibly merged!]
Facing everyone's bewilderment, Lin An adjusts his glasses:
“I'm not singling anyone out.”
“I mean everyone here, and every demon as well.”
“Your actions all pose serious safety hazards!”
“Until I achieve the Demon Slayer Corps' goal of ‘zero accidents, zero casualties,’ nobody gets to start work!”
“Hey, you, Muzan! There are problems with the structural design of your Infinity Castle. Shut it down for rectification first!”
Muzan: Don't come any closer!!!
It's too rigid and lacks emotion. Honestly, I couldn't feel any emotion in it at all. It's nothing like Demon Slayer. If it were about using rules to kill demons and then changing them without regret, that would be fine. But this is too rigid, for better or worse. It's too rigid, with constraints on both sides, seemingly very fair, not favoring either side. If you can accept impartiality, or if it pushes both sides, it's okay. But as a human who only supports it, I can't stand it.
Personally, I found the "coldness" of the rules in this book unpleasant. It's fine for characters like Tanjiro and the Master to follow the rules, but the nine Pillars of the Demon Slayer Corps are already psychologically troubled, and the supernatural elements make conflict inevitable. The process of these conflicts was quite uncomfortable for me, even though the outcome was positive.
It's quite interesting and novel.
