I guess Fujino will somehow retcon Yui's story; otherwise, it really shouldn't be possible for her to see Inoda as her dad. She spent years with Asuna and Kirito as her parents in SAO, and that’s part of her personality stored in Kirito's gear. I have no idea how Fujino plans to fit her into the storyline, but no doubt it’ll be a total mess!
Last update, we were hoping Fujino would get rid of Alice and Klein to focus more on the story, but instead, it looks like we’re getting an additional character.
