I just saw the translated chapter, and i can now tell, that the Wong families house is Akuha's last stop.
At first glance that technique didn't look like the Hougetsu Jigen Tou, but it looks like i was wrong, this is gonna be 1 hellish reunion.
As for Lingling and Fanfan's parents, at this point will assume that there fate's are unkown.
About Lingling it would appear that she was created by Touhou and can use the Hougetsu Jigen Tou, and she might even know a weakness not only that but shes a zombie, i was wondering why she was smiling.
Akuha's chance at being redeemed has decreased a lot, her fate will be unknown..., i was really hoping she was gonna be a good guy, but as of this moment the chance of that is 50/50
The present Omote-Moka appears to be re-living as her younger self her reply "Tsukune...? ...huh? Tsukune...? ...who was that again...?" somewhat confirms this, almost as if her past and present memories are merging.
I think that Kurumu and Mizore heard Tsukune's confession, judging from there faces and the way Mizore spoke.
