- Imagine a super strong looking enemy about to fight an MC that is clearly not yet capable of defeating them...
- MC falls on ass, scrambles backwards in terror until clothes get stuck on thornbush...
- Enemy begins monologue that transitions into a flashback of all the struggles in their life they've had to overcome in this unfair world...
- flashback lasts multiple chapters...
- as Flashback finally ends, the enemy having reaffirmed their determination to win pulls a super-sayian style transformation...
- Lunges towards MC, and immediately trips on insignificant pebble...
- tries to catch themself from fall, but instead manages to decapitate themselves with their own weapon.
- Fight scene ends with crying piss-stained MC wondering WTF just happened.
- Next page -> readers are surprised with MC Ahegao face from excessive level-ups... then MC passes out
- When MC wakes up, discovers brand new skill on their stats, "Trap Creation (Lv. MAX)"
- .... as it turns out... MC touched the insignificant pebble when he was on his ass scrambling backwards in terror. (which of course readers completely forgot about, after having read multiple chapters of the dead enemy's backstory)
And the story continues like this forever. MC accidentally killing enemies because he unknowingly set a trap for them ahead of time. As the story goes on, MC becomes desensitized to enemies suddenly dying... to the point that he starts getting bored and carrying a camping chair with him so he can take a break during the monologues & flashbacks.
Bonus: At some point early in the series an enemy's weapon should be deflected with such force that it shoots into the sky with the twinkling star effect. Several volumes later, a boss enemy mid-monologue (life story flashback yet to begin) is suddenly impaled to death by a weapon falling from the sky...
MC shocked pikachu face because enemy died before he finished setting up his camping chair. Notices the weapon, and has a flashback about the enemy it came from.
