No. That portrait is not F2U, it belongs exclusively to Faith and Blood project. Please remove it. I don’t accept no as an answer.
Anyways, iirc Nera’s portrait is still a placeholder. If you don’t mind you can wait for Nera’s new sprite, or else stick with the current placeholder instead.
If you also don’t mind, you can send the palette to @Rickochet since you fixed Nera’s and Monty’s battle sprites.
