Hi there. I'm the one who tried to revert you removing the Villains category for Lui Shirasagi. Just warning you that I might put the category back. Though you'll disagree, I will say that Lui isn't just rude to everyone. He has also done other things like belittle his teammates for complimenting others, showing no remorse when he gave Shu his scar, psyching out Valt and nearly injuring him twice, and usually doing things for himself rather than others (which any villain does). I'm not being rude, but I recommend that you think about this when I or someone else edits Lui's page.
Well, his teammates consider him to be a friend (especially Gabe). And the same goes for the other members of the Supreme Four as seen in his debut episode. And he seems to have developed some respect for Valt after their last battle.
