Thank you for sharing. I haven't seen this anime, but would love to watch it in free time.
Not all images available on Pinterest are free to use. In many cases you have to look for ones that are free for use or ask the author for permission. In this case, the person uploading this photo does not have the copyright to it either, because it belongs to the creators of the series, as I wrote it is a screenshot from the series. I decided to add this photo because, however, I was based on it, and it was not me who came up with this character. Maybe next time I will make the screenshot myself.
