Darn it what-if!Marin! I thought you'd be competent enough against Booba ninja. Tho the extras have established Sakura is actually pretty OP. I guess only Konoha could beat that.
Speaking of, curious as to what exactly Konoha was looking at. CivEng gave a pretty good hint but I'm still curious. My first thought was related to Aoi.
As for the other mystery: I actually think Ayaka didn't kill Yuri. Kuro successfully mindwiped her while Momiji covered it all up.
