One Piece Opening 01 We Are! Creditless Version
4:3 1440X1080p [Neo-Raws AI Remaster]

This is not the final product, this was just a recent test model output by Neo-Raws, their AI has been trained for years on One Piece episodes.
and have made few remaster versions of OP EP 01-206 and other anime,
and if you look closely, you can find some issues in few frames but those can be fixed.
