>>45070211let me explain by going full retard weeb:
Unlike Susie, who wears her high skill on her sleeve for everyone to see, Watame is, funny enough, a wolf in sheep's clothing when it comes to singing.
If it was an anime duel Watame would be the idiot underdog that has secret superpowers while susie is the obviously cool strong character.
Sorry I had to get it off my chest.
