Didn't think that I see'd this here.

So yeah, it's from a series called Wadatsumi.

Not sure how to tag this: Wadatsumi_(Manga)? There's already a artist on Danbooru with the tag using the Wadatsumi tag. Though even if I created a new tag, it wouldn't be the correct version.
So help would be much appreciated; Please and thank you.
