The current reviews. There has barely been a few chapters out, at the time of this writing 5, and two reviews have said its rushed and generic.
In the first chapter, it is established that he loves her and she possibly towards him and then they are off into a fantasy realm. Some may say that is rushed but there are a lot of stories out there that takes several chapters, even a volume or more to build up a "Do we love each other?" relationship. This manga though, says they do on the first chapter and the real story, the story in the fantasy realm, is where things start. The second chapter shows glimpse of them liking each other while the story rolls onward. Third chapter is mainly story. Fourth chapter deals with both their bond and story.
I honestly don't understand the complaint about rushing. There are a lot of manga out there that drags through the story and some ends abruptly or rushed due to publication or the author not being able to plan or work the ending. Since I'm mostly writing this review because I'm irritated at the negative reviews, I will just bash their opinion.
"Unsympathetic" main characters- Um. Compared to many other male protagonists in manga (depending on genre), Satou is not similar in the sense that he does not spend volumes whining and being afraid at his incompetence. There are dozens of weak-willed male mc that eventually grow up and become...cool. But for every one that does so, there are a lot more that simply pisses you off from their incompetence. Mainly in manga that has multiple love interests. Satou's thoughts are seen throughout along with his actions. He doesn't take up a whole page worrying about things and at most a panel or two. He loves Nokana and will fight for her. He doesn't know the strange world he's in well or what will happen but he's doing what he can to be with Nokana.
Noakana Hime on the other hand, not a lot can be said about her since the action parts are about Satou so far. But by chapter 4, you can tell that she loves Satou.
! For ten years, she hide on Earth (I assume) for her life and her true friend is Satou. Even though she comes to love him, she knows she can not stay because of circumstances so she kept it at friendship and wanted to keep him safe on Earth. But Satou came after her and now they're married. She gets to be with the one she thought was out of her reach. A barrier she built up for ten years dissipates. But she also knows the trouble he will have to face as the ring king along with him having a harem. So there will be love, comedy, and painful moments.
I do hope she gets a bit more active role but its a seinen so Satou is the figher.
"Shounen protagonist"- No, of course a high-schooler isn't a boy. u_u Shounen refers to boys elementary-high school and seinen is high-school and upwards. What really separates the two, in terms of manga, comes down to level of maturity and consistency of their themes. A quick search of solely shounen or seinen shows up more tragedy or horror subgenre for seinen than shounen. But there are horror shounen and non-tragedy/horror seinen. I digress.
This manga will NOT be like a top-tier seinen like beserk, vinland saga, kingdom, orange, etc.
But there will be mature themes and concepts.
Character that seeks "innocence/shoujo/pure" romance- Are we reading the same manga? No, probably not as nowhere does Satou nor Noakana seem to be in an illusion about their predicament. Satou may not know his surroundings well but he knows that he's there for Noakana. Noakana didn't think it was possible. They're together now and trying to work it out as the disaster is befalling the world. They're in a fantasy world... its unrealistic in that sense. Romance is anything goes.But seriously, what on earth does that have to do with coward?
tl;dr- Its barely out as of this writing, they love each other and have to deal with a global disaster in a fantasy realm. Splendid drawings and comedy with high expectations for story and if you're still unsure, read Tasogare Otome x Amnesia, Maybe's previous non-H and fully translated work.
