Yeah besides Monica it's not a hot take to think that any of these will show up.
So apparently this will be it's own book

The final chapter in the acclaimed DEMON WARS saga, SCARLET SIN will wrap up the latest era of Momoko's bold vision of the Marvel Universe that blends classic Marvel Comics storytelling with traditional Japanese folklore. Since the Momoko-verse was introduced in 2021's DEMON DAYS: X-MEN #1, these timeless tales have transported readers of all ages to a world of magic and adventure. Filled with wondrous versions of the Avengers, X-Men, and more, this unique and spellbinding experience is sure to captivate readers for generations to come!
The yokai are at war, and Mariko Yashida, descendent of the Oni King, has to choose a side. The fates of the spirit world and the human world hang in the balance. But things just got complicated thanks to the appearance of a mysterious yokai with incredible power. This yokai has a scheme of her own, and she wants to paint the world…scarlet.
"When designing Momiji, Demon Wars' version of Scarlet Witch, the first thought that came to mind to represent Scarlet Witch was her anger and betrayal," Momoko explained. "So with this in mind, I was inspired to create her around the Hannya idea. Hannya in Japan is used in Noh theater to represent a woman's anger and jealousy, and these vengeful spirits turn her into a demon."
"In Demon Days, most of my characters, even though many were yokai, were all yokai living in the human world, so they had to 'look human.' But in Demon Wars, the story takes place in the Ikai, the yokai world, so I had more freedom in designing the characters," Momoko continued. "They can be human, animal, or an out-of-this-world creature design. So I had lots of fun designing each character. Demon Wars is coming to an end, and I can't wait to see how readers will react. Thank you!"
I haven't followed this series but I think I did read one issue at least. I really like Peach's art style so there is that.
