Is it wrong to create OP skills?

He woke up, looking around he found himself inside a cage.

Ugh…

He grown.

An intense pain assaulted his mind as 5 years worth of memories flooded his head.

'I was separated from my parents during my birth.'

'Those damn demons stole my carefree life.'

Kai recalled how his mother in this world was so desperate to pass him to her friend trying to buy time to stop the demons.

Unfortunately, the person that took care of him was ambushed by a demon, she was able to subdue the demon but the injuries she got killed her, before dying she dropped my basket on the calm river letting the current of water guide him hoping that someone can pick him up.

He was picked up by a kind grandma and was raised for the next 5 years.

He lived his next five years as a normal boy playing around like any normal kid loved by a doting grandma.

However, happiness don't last long.

Bandits attack the village killing all the men and the elderly then capturing all the women and kids.

Rage began to boil inside Kai.

[The users rage is reaching a critical level, it is advised to calm down.]

Hearing a sudden monotone female voice in his head Kai snaps out from his enrage state.

'Is that you Rafael?'

[Yes, this is your ultimate skill, Rafael.]

'Open navigation, tell me what world I'm in.'

[Your currently in the world of 'Is it wrong to pick up girls in the dungeon.' In the North eastern part of Orario.]

'I'm in Danmachi.'

[Do you need me to explain the usage of the system?]

'No need I've already figure out the system's functions.'

[Do you need the general information of the world?]

'There's no need for that.'

'What I need you to do is to recreate the sunshine magic from nanatsu no taizai, you can use as much karma points as you want, also try creating a night version of it you can call it moonlight.'

[Request is possible… estimating karma cost will be 40,000,000 – 55,000,000 points. Do you wish to proceed?]

Yes

[…Skill creation is successful…]

Kai immediately felt the empowerment given by the sudden increase in his magic power.

He focuses all the heat on his palm trying to melt the steel that cage him within.

'Its time for vengeance.'

His eyes turned cold as he spread his passive domain trying to locate the whereabouts of the bandits.

250 meters Kai sense 13 bandits of different ages from young to old.

…

A person opened the room I was in to deliver some food walking to my cell the man saw that the bar had melted.

He was shocked.

He was stunned to the sight, snapping out from his stupor he turned around and was about to report the situation when a hand appeared out of nowhere piercing his throat instantly killing him before he could even react.

He didn't even get to know how he had died as his consciousness turned blank, his soul was also burn to crisp a torture worse than death.

The hand then lightened up burning the corpse into ashes leaving nothing behind.

I look at the dispersing ashes with a cold look.

Leaving the scene I sneakily move from alley to alley, buildings to buildings silently killing every single bandit I come across.

I didn't give a damn about their reasons for being a bandit, knowing that each person has a history of his own, in my eyes an enemy is an enemy nothing more nothing less.

10 minutes later.

I've already killed about 32 bandits, I also notice that my sneaky actions has been notice, no one's perfect to begin with no matter how powerful they are.

While I am on the other side of the camp a pervert guy that has a peculiar taste entered the warehouse I am in before aiming to do something perverted to the poor little me only to find scattered food on the ground and a melted iron bar.

He immediately rang the bell of the camp.

The camp is quite big so I didn't notice him because I am in the other side of the camp now the remaining bandits should have heard the alarm and were regrouping.

I don't really care about their numbers, even if they group up in my eyes they are nothing but insects.

It's not that I am overconfident or arrogant that's just the undeniable reality.

To begin with I'm only sneaking around to avoid collateral damage like when they used hostages to pressure me but now that the cat is out of the bag I have no choice but to accept collateral damages when the time comes.

I'm atop one of houses when two poor little preys happened to passed by the alley so as the predator I must respond in kind.

Before they could even react their bodies were burnt to crisp along with their souls, I could hear their screams of pain and agony.

Soul pain is thousands of times more brutal and painful compared to physical pain.

I am not really into torturing others sadly for the bandits it seems that my sunshine magic is a bit different compared to that of Escanor's

[You received 100 origin points]

[You received 100 origin points]

'Only a 100 origin points.'

[They are just normal people so the origin points received are miniscule.]

'That's understandable. How many origin points do you think I can get from killing an adventurer, Rafael?"

[A subject is needed for me to come up with an accurate answer.]

'A subject you said I can tell there's two out their probably the leader of this place and the vice leader.'

[I would be delighted if you got your hand on the two targets, but please be careful not to underestimate them.]

'I know, don't worry. I also need to estimate my current power against a real adventurer.'
