As much as i would like to like this novel since i realy love all the worlds the mc has been to and will go to but i just realy cant. Its sad to say that IMO this novel is perfect, as long as you edit out the MC and basicly everything the MC has done in this novel. Lets start with the first and the most annoying thing with the MC for me is that the MC is Zelretch's reincarnation and has all the memories except the ones about ORT and all the plans related to it, this would have been fine, great even as i personaly love nasuverse magic as a perfect mix of flashy explosions and mysterious concept magic HOWEVER for some reason all the mcs knowledge of said magic is COMPLETELY ignored by the author outside of the second magics ability to teleport and empower his avarage swordsmanship to the point where it can fight heroic spirits... LIKE THE F dude, some of the most powerful magic in the second dimension completely degraded to travel tool+swordsmanship assist, i mean you hold what is basicly the key to space but all its used for is chopping people like a mindless berserker and failing as i cant remember the mcs "birds" has ever actualy harmed anyone even those significantly weaker than him. Not to mention any other magic Zelretch could/should have possessed as with his age he should have atleast have a solid basic in every magical discipline and a complete master in those he focuses on like jewelcraft wich literaly involves his title old man of the jewels and mystic code creation with the kaleidosticks, but nope, nothing at all, the story would have been 100% better off if it was just a "mc reincarnated in dxd with the ability to travel between worlds" fic as thats the only thing while extremely stretched that could be a ability Zelretch would have as while mentioned that the mc has Zelretch's knowledge however it is completely ignored after like the first 2 chapters in the story and has never basicly never been used after that as the MC fully focuses on runes and omnyoji. Like what is the point of being a reincarnation of Zelretch if the mc doesnt use any magic or ability that could be linked back to Zelretch at all. But all this while incredibly frustrating it is possible to ignore as long as you simply "delete" the fact that the MC possesses all of Zelretch's knowledge from your mind and just continue reading. BUT... then theres the big but, what makes this novel frustrating to the point of me wanting to tear my hairs out if the character of BOTH the MC and the Author. The MC is obnoxious, like extremely. He acts extremely disgusting to every female sentient being he meets and for some reason all women instantly get together with him and even seem to like his obnoxious character, i mean, i as a 27 year old male feel disgusted by his blatant sexual harasment and constant staring at female privates so how could every female he meets be happy with it? While lovers might be flattered by doing so but for random strangers thats a good way to get a restraining order. And for the MCs character the Author just tries too hard to make it "reasonable" that it has become anything but. Almost every action the MC takes is driven by a negative personality trait he possesses, and every other chapter the Author has to mention his Devil/Dragon traits to make excuses for his actions, i mean, cant the mc just do something just because he wants to? He always has to stare at this butt because his devil nature and always has to hoard that artifact because his dragon nature blahblah, the author is trying so hard that the mc has nothing but his devil/dragon traits for him to even get out of bed in the morning. Now the absolutely worst of the worst is that the Author has a hard one for a weak MC. The mc is incredibly powerful and knowledgeable but the Author always forces the MC to be in the weakest position possible in a fight going as far as literaly twisting black and white and distorting the facts to the extreme, with this i mean if the MC is a ultimate class devil on a normal day then the next day when the mc fights a high class evil then the mc would suddenly only be a mid class devil and if the day after that the mc would have to fight a super devil then the mc would be a demon king class devil... This is not even mentioning that all his powers are used the absolute worst way imagineable as being a powerful mage with powerful magic and knowledge he rushes head first with a sword while only possessing mediocore swordsmanship that has to be suplemented by the second magic just to be able to match true martial artist types and while using the boosted gear doing nothing but screaming and punching like a mindless berserker while he is actualy a mage and can boost his magic to terifying degrees, and even a sword would have a much better effect than mindlessly throwing punches like a commong street thug, i mean seriously? what is more likely to win the fight? punching someone or chopping off someones head? All in all, after a long rant and venting my frustration and hairloss brought by this promising yet utterly dissapointing story... READ THIS if you like a underdog MC who never grows and always stays 1 step behind his enemies in both strenght and wisdom and has to struggle all the way even if he has long since outgrown said enemy. DO NOT READ THIS if you hate a weak MC that will never grow stronger and has a overall rather obnoxious character that makes him look like a xianxia MC without self will. And a Author who completely twists black and white and falls into the same pitfalls over and over again with his underdog MC fetish.

This is great! So far there is only two chapters out but within these two chapters it left me excited and expecting for more and I can confidently say that not a lot of fics can do that to me. I came here to cure my boredom with some mundane fanfics but left expecting more of this budding fanfic.

meh, author start giving strength to other characters than mc....especially after mc kill the dragon but his friend who's got the war spoil.....meh.....when mc isn't strong and op enough.....

It's a good fanfiction, can he go to The Irregular at Magic High School, I think it's the best modern system magic. . . . . . . .word count. ......................

I truly regret reading this fic. When the Mc is weaker than the talentles issei even with second true magic and boosted gear, you know he is trash ☹️☹️☹️☹️☹️☹️😕😕😕😕😕😕☹️☹️☹️☹️😟😟😟😟😟😡😡😡😡😡😡😡😡😡😡😡😡😡

Another book ruined by contradictions and no storyline so the author and his incel audience can have 400 fictional girlfriends to sate their sad and lonely lives. I’ve seen the discord, I warn you to stay away.

Well the story is written well but MC is an underdog most of the time. Everybody that matters in the story is stronger than him and those that are weaker than him have more potential than him. Mc literally keeps on praising talents of others while every power he gets is like minor upgrade for him. Every fight it looks like he is using everything and barely comes even and even then he would say things like 'I am lucky he didn't gave his all' or 'he could beat me in a physical fight if i didn't use this trick'. I mean i don't want a xianxia mc but nor is it fun to read a deadbeat mc, I mean i read an entire arc of story and was hoping wow now this mc is op when then our mc start telling all the limitation his power has and he can't use rest because he did not know how to use it, Plus he is a devil but do not use devil magic god knows why, has destruction magic but can't use it without support of a tool, has aura but can't activate semblance so it is only useful to enhance his powers a bit. Frankly if the story was not interesting i would have not given it 3 stars i really hope author does something to make mc relevant.

just aint for me. This ff is like those op mc that some authors keep nerfing.

the harem has more progress than the story in summary the mc a half devil in dxd is abandoned in human world his father is the satan he gets memories of zeltrech from fate he stole draig he tantrums he escapes from the whole dxd world he goes to skyrim world in accident he learns magic he sees a beautiful goddess he confess he got harem num1 from Skyrim he kills a dragon he then goes to fate world he sees artoria he invites her to date harem num2 he meets zeltrech he becomes his grandson he then goes to see scthach he begs he to teach him then 2years later harem num3 then he returns to dxd he meets another goddess its izanami im sure it'll become harem num4 he heals a kid and im sure itll become his daughter or something then the mother becomes another harem member the only important girl character that isnt his harem is rin because she is his disciple as zeltrech overall another story ruined by harem
