Huh. Stumbled upon it by accident while listening to lofi / chillhop playlist on youtube (probably not the weirdest way to find something new to read) and it picked my curiosity because of similar "reincarnation" - "past (life) plays a big role" theme that "Bokura no kiseki", "The Moon that Rises in the Day", and "Spirit Circle" are using so well (although that last one in a slightly different manner ; all mentioned titles are great by the way).
Can't tell much yet, but judging by first five or so volumes and the way that everything - from art to crudely generalized "storytelling stuff" - improves throughout them, it looks like it'll be at least fun.
