Watched the anime like a decade ago and never realized there was a manga wth. I DEFINITELY Recommend watching the anime, it was so good and if the manga is anything like it then it should be great as well.
You may feel your favorite manga should be gathered together into distinct categories for your own reference and, now, you can do this with a LIST. After you've created your list or lists, you can proudly recommend them to other manga fans to showcase and share your taste in manga.
