Well, just to start, I think you could've bumped this thread, and Sonia's, just so everyone knows you updated the story.
Also, about what I said on the previous post, apparently, the story code can work to make only one character talk with a specific boss, just saying in case you wanted to make a boss like Blackmore to talk, Serio also mentioned in another thread that another character could show up (I don't remember which thread, but Serio used an example of Dmitrii beating Alucard, and then Alucard runs away when the player arrives), though, no killing the other character, to avoid paradoxes.
Now, for the story itself:
Aeon: Greetings, you come right on time.
Minor typo here, should be written "You came right on time".
[Alucard VS Dario]
Dario: Huh?! Not you again!
Don't think Dario ever met Arikado when Julius and Arikado went after him, only Julius was there, for whatever reason, there's the chance that Dario saw him though, but maybe he wouldn't recognize Alucard with the different hairstyle and clothes.
(Alucard enters. There is one of Shaft's green orbs hidden in the screen, but it does nothing)
Is it really possible for it to be there? Just to make sure, it could also leave when the battle begins.
Alucard VS Carmilla
Alucard: The castle changed a moment ago. It seems it wanted me to come here before reaching to the throne room.
I think this kind of dialogue should be saved for Aeon when Alucard talks to him before fighting Agni, because when Alucard reaches Carmila, he really should have noticed much earlier that the castle's rooms are a mess, him talking to Aeon about this could be an interesting conversation from them to have.
He will take care of you... once the time comes! )
Dies)
Minor typo here.
Alucard VS Shaft
Shaft: Is that so? Have you ever asked yourself what made my Master succeed in my world?
I'm pretty sure Shaft is supposed to be from the same timeline as Alucard.
Alucard VS Richter
This whole conversation needs to be changed, Richter is supposed to be "possessed" by the Doppelganger, who is controlling Richter because of his desire to keep fighting, or, something like that, only exception would be Richter vs Richter, where he instead faces the doppelganger itself.
Alucard VS Dracula
Trough the ages you have been holding to a meaningless revenge
Minor typo here.
It's also a bit odd that Alucard got so emotional to the point of even mentioning his mother's last words to Dracula without being asked, also odd for him to call this Dracula "father", and even more odd for Uber Dracula to call him son, not saying either is bad though, just saying here.
Dracula: She... was the last tie I had with humanity, and why I decided to stop looking for revenge.
Dracula wasn't really at war with humanity before Lisa was killed, after all, even Loi's epilogue says it would take a long time for the Belmonts to face Dracula, and they would have faced him far before Trevor if Dracula started the war at those times (Leon would even probably be the first one to kill Dracula), between Loi and CV3, Dracula was probably only butthurt with God, not humanity, Lisa being killed is what started his war with humanity.
The Somacula dialogue may need to be changed, not sure if it's approved, but player Dmitrii, player Dario and player Celia are planned to be from the same universe as Somacula, which means Somacula's universe could have a background, and Somacula himself could end up having more story/personality than just being an extra boss who shows up out of nowhere.
Anyway, story was pretty good, I'm not really sure if Orlok should have that talkative personality though, there's a Castlevania book which takes place after Dawn of Sorrow, which was translated, somewhere, I remember reading it once, Orlok's personality wasn't as talkative if I remember it correctly, and I think it'd be better to use the personality he has on that book since it's the closes to a personality he ever had in official stuff.
