New prey

Not sure where to get her next acquisition, Mikasa's powers dragged her to an unfamiliar place, some sort of gym that only a sibling pair occupied at this moment. Mikasa overheard them calling each other Ted and Mia, and saw how their sibling dynamic operated.

While Mia, the little sister, was thin and weak, trying to catch up to her brother in strength, Ted was powerful and commanding, regularly making Mia act like some assistant or secretary, rather than someone he would help train. It was clear that Mia was completely subservient to him and that Ted failed to properly care for his fragile and pale sister. That's when Mikasa felt her powers reverberate, telling Mikasa in its own way that this was what it wanted her to do, these were the people it wanted her to help/change.

To make this a reality, Mikasa's superpowers awakened another ability connected and controlled by her power: the ability to transfer energy, rather than purely creating it. Instead of Mikasa's usual MMO, where she transformed a person and tempered them whilst they changed, this sub-power allowed Mikasa to tie one person to another when relating her power, making it possible to go beyond simple milf characteristics. Mikasa could tell this wasn't all though, for while this was an attribute swapping ability, it still was a part of her milf power, meaning whatever got changed still had to become a milf in some way and couldn't be directly morphed without consideration. Because of this, Mikasa acted gently on this newfound power as she sculpted Mia, putting extra amounts of detail and work into shaping her beautiful body, making sure to pack every spot with muscles, but also that Mikasa' focused on attractiveness and flexibility, keeping Mia at a perfect ratio where her bust wasn't overshadowed by table-sized biceps. As for Ted, Mikasa made sure to give him the treatment he deserved, transferring all that muscular magic as he became smaller and younger, his cock slowly shrinking as he freaked out more and more, allowing the growing Mia, both physically and mentally, to act like a parental figure and sooth Ted's worries. Even as he still feared for his developing state, he couldn't help but feel comforted and calmed by Mia's presence, admiring how his almost albino sister turned into a tanned bitch with short brown hair, giving her a sexy muscle mommy tomboy look.

Ted wasn't so lucky; she was no longer a man, super strong, nor an adult. Ted had become similar to Mia's old appearance, small and frail with very light skin and silver hair.

In this new situation, Mia fit into her role perfectly, comforting Ted as they worked out together, having a proper, fair, and just familial bond. When they eventually went home, everyone only knew the two as they were now, not as the people they were before, no matter how much Ted protested otherwise. It wasn't long until they completely adjusted to their roles and their expectations:

• Mia had become an MMA superstar with one of the top 10 naturally beautiful faces, vastly outclassing girls from the Miss World contests.
• Ted was still young, but she would grow into her future, becoming a fit but normal person in terms of muscle refinement, growing into a tall, voluptuous goddess at 7'5ft with light skin and super big honkers in all parts.

Their new lives would be filled with light and joy as they treated each other equally and fairly, a far cry from their old lives where Ted would ignore and push Mia away, trying to live up to his dreams of becoming the world's strongest despite losing in all preliminary matches.

As for Mikasa, she soon claimed her prize by transforming Ted into a milf with 2 forms depicting her new backstory, her present form as a youngster and her future form as a sexy mama. She has memories of the future and has gained a clarity over her past, but is far more focused on her love for Mikasa alongside her sister, transforming into her milf form when she wants to live that life, but transforming back when she needs to fulfil her familial and social obligations for her younger years. The aspects about her future are true; however, they are altered slightly so Ted still has the sexy aspect as a regressor with a hot body, but also so she loves Mikasa, thanks to an added backstory element where Ted had an impossibly great time with Mikasa but broke it off to pursue other things, falling in love and having children, etc, etc. This way, Ted still had her own life and choices but still wanted Mikasa's dick, making it super alluring for Mikasa who got to fuck a woman from the future who's crazy about her, doubling this fun with Mia and beautiful body.
