So i'm not one to judge an author's works, but this mangaka has some sketchy stuff in her past and makes me wonder how she ended up drawing such a cute series
This comment made me look up Tomekichi's stuff on sadpanda and it looks like her favorite thing is crossdressing/gender bending. Somebody probably suggested body swapping to her as a natural extension.
There is some history of that - look at the author Higashiyama Shou - he did a great, cute series Prism - it got cancelled due to plagiarism of an ad, which I thought was nonsense. He did a great, cute series, Stretch. Look at his listing on Manga Updates:
Name Genre Year
Adult, Hentai, Lolicon 2007
Adult, Hentai, Lolicon 2008
Adult, Hentai, Lolicon 2010
Prism Comedy, Drama, Romance, School Life, Yuri 2010
Adult, Drama, Hentai, Lolicon, Romance 2013
Stretch Comedy, Drama, Seinen, Slice of Life 2013
I don't think his other stuff is worth searching.
