I could be wrong but iirc, Sweeper was just a random, nickname/obvious fake name he gave until they found out or otherwise learned his real name: Weibao
probably a mix in translations? a lot of scanlation teams dropped this before other people picked it back up.
Can someone remind me why Sweeper's name is Weibao here? I've read the raws and it's always Sweeper this, Sweeper that, never seen Weibao anywhere hahaha
