You were Tamayo's wife a demon just like her you two became demons at the same time as well this is during when Yoriichi fought Muzan you and Tamayo had to come as you too were his upper moon one and two. Right now you two were watching the battle between Yoriichi and Muzan a small shine was your eyes because you thought this would finally be the time you get out of Muzan's control Yoriichi must have seen it because he froze for a moment an that was all Muzan needed to get a hit on Yoriichi when Muzan did that you and Tamayo shared glances you both knew Yoriichi wouldn't win this alone so you and her rolled your sleeves up cut your hands an pointed them at Muzan ice spikes shot up under Muzan in paling him that was your doing because of your blood demon art and Tamayo made illusions with her blood demon art to confuse Muzan and hopefully give Yoriichi a wining shot.
