- Kiara's upbringing in FGO
Same as CCC up to 14.
After recovering, she gets out of the mountain, and has a happy student life.
She saves a lot of people, but is attacked by people who felt their positions were threatened by her great success (that she did for free!), painted her as a bad person, and she ends up on that oil plant. Not that she minds, she wasn't unhappy.
If Zepar didn't happen, the worn out workers on Seraphics would've been soothed by Kiara.
- Lost Man
The reason he restarted at the end isn't because Kiara said things about him, but he stood up because she called the people who drove the nameless hero out disgusting.
Like "There's no way I can just let you say that and do nothing".
- "(BB?) changed destiny so we won't meet"
If CCC happens, there will be trouble for him/her.
So even if the entire world forgets, and BB remembers forever, she defines "we did not meet", and put a lid on her dream, to protect that future.
Timeline before the event started
- January
Zepar comes to Seraphics, starts taking over. Starts digitalization.
Picks Kiara as his hiding place when he is found, and starts recovering.
- February
Riots and confusion. digitalization progressing. Kiara feels her mind rotting, but does her best as a therapist.
- March
The morale within Seraphics is at the limit.
Zepar introduces himself to Kiara and starts working together. Finds out Kiara's life in other worlds, thinks it would be useful, and pulls her ability from EXTRA. (*: reason it worked)
Seraphics starts turning into SE.RA.PH., sinks but is still running because of 電脳化. Time starts changing into SE.RA.PH. time. Kiara (Zepar) starts turning the survivors into a cult.
Kiara succeeds in opening the astronomy room after a bit of trying. The deputy was too scared to do it, so the dirty work dude pulled the lever at the end. (Incidentally, he was the only person in the workers who did not have a physical relationship with Kiara.)
Servants summoned, time changed to 100 times faster, HGW starts. Zepar loses his freedom around this time.
- April
Kiara salvages BB(GO), Melt, and Lip to use.
BB/GO tells the survivors "you may survive if you keep quiet, oh, but by the way, time is different, so it'll take 50 years until help comes".
Survivors fighting intensifies, basically "Mist" by Beckman. Anyone who goes against him is thrown out, feeded away, or ordered to attack Melt and co who were looking around SE.RA.PH..
BB/GO pretended to obey Kiara. Melt and Lip know they can't go against Kiara (because they were salvaged from her), but having hostile feelings, after a bit of neutrality and understading the situation, went against Kiara anyways. Melt was disposed of, and Lip was sealed.
After HGW-ing for a while, Kiara becomes a immature Beast, and starts making her "main body", and chooses SE.RA.PH. as her body to become a beast. SE.RA.PH. starts turning into Kiara.
At this point, the human Kiara becomes a sub-unit that she can throw away at anytime. (Zepar was clinging to this.)
Sensing a Beast, Mooncell grasps the situation, sends BB to deal with it as CCC.
BB immediately figures out that the situation is way out of hand for her to deal with, and issues an order to cooperate with the local humans.
BB and BB/GO discuss their goals and switch. From this point, SE.RA.PH. is run by Mooncell BB, and to keep Kiara from finding out, she pretends to act like "admin AI under Kiara".
By the way, Zepa-something is gone around here.
HGW continues.
- May
Kiara finishes her SE.RA.PH.-fying. Goes to Mariana trench in 2030.
Kiara's greatest mistake, Ms.Trapaine manages to get to the communication room (with secret help from BB), and sends SOS to Chaldea even as she is dissovled. BB honors her last efforts and gives a proper burial for her. BB also vows to make this entire incident a 虚数事象 (imaginary number event?) and save all the staff. Everyone, except Zepar and Kiara, that is.
Kiara recognizes the situation, and leaves dealing with Chaldea up to BB. BB says she'll annoy them, does that too, but invites Chaldea's master as their only hope.
Guda arrives, but Kiara's restrictions force the servants that tagged along to scatter, and they are defeated.
Alone, Guda escapes from insane servants, and manages to get into the church. There, they meet Meltlilth, who is about to stop after being thrown away. They make a contract.
Because she was initialized, Meltlilith is very docile and at Level 1.
From Melt's POV, it was like fighting a bunch of Kamen Riders as only one Shocker fighter(?). It was scary, tought, but everything about this was precious for her, and that was the reason she did her best.
They ran out of time, and SE.RA.PH. reaches the bottom (and goes beyond). They managed to save Passionlip, but couldn't take off the restraints. The three reach the astronomy room but Kiara dissolves Guda. Melt jumps with the help of Lip.
- 30 minutes before the event starts
Melt reaches SE.RA.PH. of 2 hours ago.
BB, sensing the irregularity, contacts her, and Melt shares her memory to make a plan. "The plan to off Kiara without being found out by Kiara" starts.
BB starts making the slot and KP, so Kiara will think they're only for annyoing Chaldea.
Melt visits the church, and meets the discarded Melt, for a lonely farewell.
The master from Chaldea arrives.
BB heard from Melt that the servants will be scattered, picks three servants from Chaldea and forces them here. To keep Kiara from getting suspicious, she made them believe "we came with Guda".
The three originally accompanying servants were secretly collected by BB/GO, instead of being caught by Kiara.
*:The reason Zepar could (unluckily) pull Kiara's records of CCC
The incident by Kiara on Mooncell is a 虚数事象 (imaginary number event?), which is lost in the Universe of Awareness but is barely recorded in the Universe of Record.
... so, Zepar shouldn't be able to look it up even if he can see parallel worlds.
But, Kiara is a Beast candidate, and has Authority of Beast, which is basically "destiny instakill resistance" ( this was mentioned in Babylon, regarding Tiamat), and this extends to records in 虚数事象. Thus, even if the Kiara incident is rewritten to "didn't happen", records of Kiara doesn't disappear.
