This is an interesting manga, but it feels like the art and the presentation are often at odds with the tone and events of the story. Many of the chapters start out seemingly lighthearted, but involved some sort of twist or tragic ending. Perhaps because of the writing or the restrictions imposed by many of the chapters being self-contained stories, the emotional payoff that these chapters tried to achieve felt cheap or unearned, at least to me.
In the first quarter or so of the chapters, Elaine, who is a self-professed powerful witch, comes off as cold and self-centered, doing nothing to help people despite it seeming well within her abilities to do so. She eventually has a conversation with her mentor about this, and her mentor states that magic alone can't help people. This seems like an easy out taken by the author to excuse Elaine's apparent indifference because we see as the story progresses that magic is very powerful, and witches like Elaine have a certain amount of status in the world, and magic could definitely have helped some of the people she encountered. Elaine does become more proactive in helping people as the story progresses, so maybe this is intended as character growth, but it does portray her in a pretty negative light early.
As to the chapters and stories themselves, it seems like the majority involve some sort of tragic twist or death, which feels at odds with the conceit of the story being presented as the wonder of travel, discovery, and exploration. Most of the towns Elaine visits harbor some sort of dark secret, which dulls the shine of seeing each new town considerably, when you just end up wondering what the new disturbing truth will end up being. Elaine and her fellow witches generally end up being fine, but that just conveys the message that if you are well off and powerful, you can go where you please and see the world, but for everyone else, the world is dark and scary.
The main characters tend to be well-written, and all of the different towns are distinct (if not secretly evil) making the world overall feel well thought out. Those parts of the story are interesting to read, but the constant turns toward death and tragedy bring down the work overall and dilute the impact that any one of those death might have on its own.
