Hello there, welcome to c/whatanime. A community to help you find the source of anime or manga scenes you query.
Before posting your first query, you should look closely at the query you’re going to post for any clues that might easily hint you to find the correct anime. If not, use these known reverse search engines (there are alot more, but I find these to be the best ones):
Additionally, you might try these below:
If reverse search engines fail, you might also try to search (if any) text that is present in the scene. (though this most likely won’t work well)
If those fail, then you should consider posting a post here. Well then, have a nice day.
PS: Any questions can be asked in the comments for now.
PS 2: Though not very needed right now (as this community is pretty much not known), anyone that wants to be a moderator can request to be one in the comments.
