New additions to the family

"Youmu took a step back, nearly tripping over her sister. “Just… just leave us alone! We don’t need your help!” She flared up her wings, trying to make herself look scarier. Utsuho huddled behind her, timidly.

The woman shook her head, sadly. “I think you do, little Youmu... I know you two have only had each other to stay with. That you try to work together to protect each other. That you try to fight off any of the more threatening things like a samurai, and your sister tries to carry more so you don’t hurt yourself.”

“My name is Komeiji Satori.” The woman’s eyes were gentle, as comforting as her hands were. “I have a sister I love very, very much too.”

The two sisters looked up at her. Utsuho spoke first. “Y-you do?”

Satori nodded. “Yes… and I’d stand up to a youkai twice my size and still try to fight them off too, if they were trying to hurt my sister. You’re both beautiful little birds… can I ask you something?”

They nodded, and Satori spoke. “...Would you like to come home with me? If you two help me protect my sister… We’ll help protect you two, as well.”

New arc: Yester/Youmu!

SUMMARY: The world has ended, but five (well, four and a half) humans get a chance to do it over, and make things right. Only problem is, for their second go around, they're not going to be 'human'...

With the reborn Inaba Akyuu and Kicchou Reimu now awake and active, they begin the search for the other three 'Immaterial Children': Marisa the Ordinary Magician, Kosuzu the Youma book collector, and Youmu, the half-phantom swordswoman. It is the third of these three that they manage to make contact with first.

But perhaps the ripples in fate caused by attempting to defy it go deeper than any of them yet understand...

Based on "Yester/Youmu", 3rd arc of "Redo/Reimu", a fanfic by Gooboi at Ao3.
