This is absolutely crazy. There is supernatural powers and time travel and a fair amount of death and a tiny bit of rape and the like. Seriously though this might be the most mind melting manga I've ever read and that is a pretty high bar to clear. 
I'm not even kidding there's reverse causality and I don't know if you know this but thats always pretty mind fucky, and this manga really layers it up pretty thickly. 
Suprisingly there aren't any largly noticeable plot holes, which is the Achilles heel of all time travel, let alone one this complex. 
The art is stunning but sometimes confusing because how much detail and angles it has. 
The plot is somewhat inscrutable which is true of many time travel stories, but the time travel is actually quite strong while the plot otherwise is the inscrutable part. 
I can't tell if there were some problems with things being lost in translation, or if the story was confusing by its very nature, but it was hard to follow on ocassion. 
But I think the uniqueness of this manga's story compined with its amazing visuals and strong characters makes it a worthy story to give a chance. (Side note I enjoyed the romance and drama quite a bit, so even if you aren't usually into seinen you may enjoy this.) 8/10 

Fuck this is so god damn cute

Perfect 200/10 
Even better the second time! 

You're home didn't just have one just like it, that's the one that used to be at your home! 

Oh my fucking god I'm rereading this and only just noticed that that's Miss Ume!

Was a tree that was cut down and made into a bench? I think thats what it was. 

I love those tree spirits so much. Adorable. 

The two from Ying Yang heaven? I actually like the first one. The shy one I don't give af about. 

They don't actually have an affair though. Revenge yes, but no affair. And the revenge was suprisingly good. 

Unexpectedly good revenge plot. The title and stuff makes it sound like it'll probably be some generic romance trash that only has 3 chapter of kind of revenge before becoming a generic romance, but the story actually stayed pretty focused on the revenge aspect. 
I will say I hope there's an epilogue or maybe a sequel that has some more romance in it cause the character chemestry was pretty good. 
Anyways I went into this not expecting much and came out plesently suprised. 7/10

She seems like a vain person so I bet all the rumors about her will absolutely be a great punishment for her. 

Thats a fair point. I was also wondering why they didn't bring up his internal energy problem for this. I guess the author should explain it more. 

Yes perfect. Make the rumor about her being pierta's mother! This is perfect. Now they never need to seperate!

This is the definition of a tragedy. It didn't have to have a bad end. Sigh. 

The MC is an unrepentant murderer and yet its hard to feel like she's a bad guy in this. Truely a psychological mess. 

Also there are so many fucked up people in this story that it can be hard to read sometimes. 
Still if you wound up here somehow I suggest trying it. Good use of an afternoon. 7/10

I can already tell she isn't in danger. Probably is sleeping as to gain something important. 

You'd have to go back to when he saved the poison body girl to know the exact details of the technique, but the general idea it he fixed a flaw inside her body. 

Yeah go turn her on! 

I wouldn't go so far as to call it a favorite, but it has repeatedly been suprisingly good. An entertaining read. 

He's at the ninth realm, considered the practical limit. Reating the creation realm is so esoteric that its never been done and nobody knows if it really exists. Only Ink might have come close and even then Yang Kai thinks Ink is only pseudo cration realm. 

He hasn't explained to that many people. His sister might actually not know.
