She might beat yusuke and maybe even yomi and she certainly has the power for shigure and Kurama but only in individual fights. She absolutely couldn't do this in a gauntlet form. All these characters are as strong as her give or take a little if she gets past one it would be good. Also gauntlet or no she cant beat Raizen who was still considerably stronger than yusuke after starving himself and moments later died from it. Even at the brink of death Raizen was stronger than the 2nd or 3rd strongest known demon.
She runs it if Raizen is not in his prime. With her cutting through space time and all I think she is the strongest THS character next to ful power raizen. If she could get to 100 percent she would have won the Makai tournament.
