I don't know if it's right to ask there,but someone know which manga it is from this picture or the mangaka:http://reader.evilflowers.com/content/comics/yamatonadeshiko_shichihenge_4e3586e3d1d0b/118_0__4f442df5a2046/YS_credits.png 😕 😕 thanks for the help 🙂

Hum.. according to the picture's size and colors, it looks more like a fan art or a simple illustration.

I doubt it is from a manga, but I may be mistaken.

It is a jacket illustration of the album "Transmigration" by starry garden.
The artwork is by apt.

Image source: Pixiv.

thanks for the help 🙂 It's a pity that it is not a manga 🙁
