38 chapters in, Mr. Mallow Blue is one of the best body swap manga series and one of the better romance mangas that I've read. In a rare move in either genre, the characters are complex, interesting, and don't seem to act in strange ways simply to progress the plot. In an even rarer move, the manga doesn't use the body swap mechanism to make up for bad writing either. The story doesn't waste time on pointless flashbacks just to fill up pages--the flashbacks help to reveal more about the characters, and the reveals make sense. Unlike most body swap manga, "Mallow" also doesn't rely on SA scenes toquickly progress the story along or rely on a bunch of fanservice to distract from bad writing.

As you can tell from the cover, too, the art is great, especially in its use of watercolors and, in some chapters, well-placed splashes of color.

Akaza Samamiya (the mangaka) makes particularly great use of facial features, especially in Tsumugi's and Aoi's expressions.

That said, it's a small grievance but, for the first 30 chapters or so, it often feels like the characters' faces look weird from the front--the faces are too long and angular, too short, or somehow both. The lips can look a little weird, too.

Again though, it's a small grievance and it seems to really improve in about ch. 30 or so.

Fair warning: There's also some self-harm and suicidal ideation in the story.
