The idea in general is good, but the story drags on for too long. And to make matters worse, each chapter is released monthly with a few occasional breaks lasting 1-3 months. And another thing... why couldn't this series be more romance driven. There were some moments that could've led to something romantic or sexual, but they get interrupted by some cause and then the moment's gone. Since this series focus on only 2 characters, with them being alone together until Vol 4 and onwards. I say that's a real shame, this series could've been like Aki Sora but with a Lovecraftian twist. In terms of brother-sister romance that's also sexual, but in this series' case the two main characters are not related. Hell the two are not even from the same race, with the surrogate sister being an eldritch goddess.

The initial idea is sweet. An orphaned boy just wanting an older sister
But there's really no particular plot. It just plods on. There are sweet moments though.
However, most of them are ruined as the "sister" does ecchi things to the 14 year old kid.
It's...weird.
Case in point, the sister has to put her finger in the boys mouth because Japan.
Then the boy thinks, while flushed "onee chan is violating my mouth".

Ok. So if you like that kindve stuff it may be for you.
But otherwise, keep yourself from vomiting and skip this manga.

The manga is built around the adorable and totally-not-sexual relationship between Yuu and his summoned Older Sister-cum-Eldritch Horror Chiyo. And for a while settles into what is essentially familial SoL plotting.
However as things go on more ideas and a more coherent plot starts to be introduced along side other Demons and their summoners. However, the issue comes in where ideas of conflict are brought up and then just let sit as the story shifts back to SoL familial scenes while still hinting or baiting conflicts arising.
It makes for a rather awkward read as points get introduced and then left to sit as the story loses focus.

Its generally enjoyable on the merits of Yuu and Chiyo playing off one another well, but the introducing and then half-hearted progression of the plot or character conflicts makes things unsatisfying.

It's an ecchi but it's also really cute and the characters have developed backstories! I'm not sure where the story will end up it's mysterious, but I like this a lot. Art is nice and I want to know what happens in the plot next!

The author likes Cthulhu mythos. Whether or not they author will introduce new characters in currently up in the air since its based off two doujins. Author promised to still ero works though.

...and thus it should come to no surprise that it (in my opinion) remains on the hentai side of ecchi (it has generous amounts of what is essentially full nudity). I think the art is aesthetically pleasing, the mc's not super developed (as of chapter 2) but likable, and it has a pretty interesting premise. I'm looking forward to seeing where this goes.

Manga, produced in a society that I gather is very well-behaved, seems to specialize in breaking boundaries. This probably gives those mostly well-behaved Japanese readers a relief from all that obedience to social norms. This series seems to fit in the new boundary-breaking category, "love for bizarre girls". It's a fun category, and this entry looks fun, and, indeed, heartwarming.
