Random check, what level is everyone at, and where are you on the story?
290, and I'm in the same boat as zydine in terms of content afaik.
...Small rant I wish to vent, I kinda wish there was a way to help Fang remember her life before she died and Kotone reanimated her. It pains me to no end that I can't seem to help them with that, ESPECIALLY when Fang actually has dreams about her death, which makes me feel like there may potentially be an actual way to help. But no, I have not been able to find a way to do so, and Kotone just has to live with the fact her best friend has no memory of her after all she went through to bring them back from the dead. Man, why does Kotone's life up until meeting the player character just give her L after traumatic L like that. She's been through enough, just lemme help mend this last wound of hers...
The thing is, as I (and, apparently, Kotone) understand it, those are not her memories.
She isn't the old Feng, she's a new person. It's more than just a lack of memories, Kotone says as much. Old Feng is dead, and new Feng isn't her.
Rather than "Feng resurrected", it would be more appropriate to say that Feng jr. is the daughter of Feng sr. and Kotone - sired through Old Feng's flesh and blood and Kotone's magic.
That being said, the secrecy around that is still an open wound, and Feng should really be told why Kotone used her magic to animate that corpse, why she calls her a "protector" but never lets her actually protect anything, and why she's clearly both caring and distant.
To Kotone, Feng is essentially a shared child from a dead loved one: Both a dear reminder and a painful memory. And Feng really deserves to know that.
