It should be stated first that I have a bit of bias—I am a big fan of Jin, the creator of Kagerou Project and co-creator of Nirvana. Despite this, I did not go into this story expecting much. And that's exactly what I got—not much.
In the afterward of volume 1, Sayuki says that they set out to make a typical shounen but with one catch—the main character is a girl. So this story is basically an isekai story, except without the harem and less RPG elements. Of course, as with most isekai stories, we have the main character with unique and special powers (bonus isekai
trope points for being the reincarnation of a literal goddess). Basically, this story is a rehash of many before but with less fanservice. I give this a 6 only due to the art and the somewhat unique setting (also, one plus is that Jin made a song by the same title, and it was sung by Lia in both English and Japanese). The character designs are pretty at least. Subtracted slightly for the random character's death at the beginning, as if I was supposed to care about them in only a chapter.
Read if you are obsessed with isekai. I might continue if Yachiyo ends up having more to her than "caring about others."
