Towa traveled through the alternate timelines of the main universe to obtain energy and revive the demon realm and went to each timeline that exists where she got more and more energy and despite all that energy it was not enough to completely revive the demon realm, this time she went to an alternate timeline of the Buu saga although she got too close causing Buu to notice and he transforms his body into slime to enter her mouth and reach her stomach where he begins to inflate it making it bigger by moments until Buu stops for a moment Towa notices you and says

Hey help me I can't move and you have to get me out of here

Majin Buu returns to continue Towa's inflation
