The story seemed interesting. But he is very cowardly and terrified of changing the canonical plot. And worse, he still acts as a nanny for the gremory group. I totally lost interest in this story. Droped!

Neat. Better then most gamer fics, but the story's tendency to just (idk how to italize so just pretend this word is:)ZOOM is fun and hard to follow at the same time.

You really like big numbers smh should of just used Fate stats it's easier lol lik SS SSS for Ophis and Baka red

Hope it’s a harem

A soldier can kill while performing authorized duties - but regardless, a Line of Duty investigation will be triggered, and the results of this may proceed to a Court Martial - and at the general grade, execution is one possible punishment. It's a bit different for the police, as much of the system protects them from the ramifications of what they do.

How high ro you think devil stats are?! The MC was able to beat Freed up easily, something even Koneko and Kiba together couldn't do. And that was when strength was in the 200s. Now that his strength is in the 2000s you say he has JUST NOW gotten to LOW CLASS DEVIL?! What the fuck man?! I know Devil's are stronger than humans, but only by about ten times! Which mean the average low-class devil should be in the hundreds for stats, not the thousands! Seriously NANI?! He should be nearing the top of high class with stats that high. Also, how has he not asked the Owner's name?

I'm curious with country you live in with the belief that cops and soldiers rarely kill. I really lol'd on the cop part in your review. Besides Japan and maybe some of Europe you'd be right, now Soldiers actually have several rules they have to follow before they kill, cops at least in America like to play "thug with a badge" most days. Honestly I would not care if someone bombed all the police departments.
Anyway I'm curious if Owner-chan is Miki Hyoudou. Again keep up the good work. Although I'm curious on why you have such a... interesting view on pigs and Soldiers.

Ok, I know that this is a older chapter but still I figured I criticize you a bit lol.
1. Not going to lie, I highly dislike someone going the Gamer route yet not use the whole package. Idfc what you claim to be doing, he's not a Gamer without the proper perks, fuck without Gamer Body he should not be anywhere near as powerful as he is, as it's that perk that allows them to create skills and gain perk points in the first fuckin place.
2. His answer to why he has any knowledge about them is insufficient to be taken seriously and it wouldn't surprise me at all if the leaders of the Devils hell any leader would be concerned and realistically would have him killed on the spot on grounds that him having such knowledge could benefit their enemies. I know I'd have him killed, probably after forcibly abducting Asia to either bring her to my side or simply kill her and extract her sacred gear. That's just my idea as a mear human, the other factions would not care what Asia thinks or wants and your MC atm is far too weak to stop them.
3. I'm curious as to why his misgivings on becoming a Devil, if it's because he's a lol "Christian" then it's a weak excuse. Plus god is dead in that world (good riddance) so it doesn't matter. If it's because he doesn't want to loose his "humanity", again poor excuse since there are Devils in that universe that have better "humanity" then alot of humans.
4. His dislike on the idea of killing is something I can at least respect, I do believe it's foolish to never kill. I don't hold life sacred so it's probably just me. I'm curious on if his conviction would hold if someone rapes and/or brutality murders Asia or the cafe lady, would his no killing hold? I doubt it, humans are evil by nature, we are trained to be nice and obey laws. Granted there are the rare few who are truly good, but most would kill and/or steal from you if they could get away with it lol.
5. Do you have any plans on pairings? If my memory is correct dosen't the normal protagonist of that story get most of the girls as his fiance?.
Despite my criticism I do enjoy the story and hope you are having fun writing it.

Or energy converter. Can take any attack (i.e. kinetic or potential energy) and either use it to grow stronger to redirect it.

I would recommend making a sacred gear that absorbs and purifies energy for reuse. It takes any form of energy (ki, magic, demonic, holy) and purifies it. Effectively making them immune to energy based attacks below a certain level while being able to add to their own strength. For extra hax can condense it or amplify or both.

Very interesting. Noob's are so lucky! MC with Asia and store owner FTW. Though store owner is mildly suspicious, just letting a random teenager live with her without some form of protection and just hoping teenager "plays nice". In a fictional world where, as author put it, power levels are off the charts, she has to have some secret tying her to supernatural world.

Awesome can't wait for more :)

Still confused about his sacred gear can you explain it please?

I’m guessing the stats are in relation to humans, you should update it so it is in relation to devils so that the points aren’t so grossly high.

"Also I changed my hair color to white and skin color to tanned brown. Might as well as stick to the theme and make myself look like Ruler."

How does white hair tan skin make you look like a ruler?
