History Characters / PassingDays

* MoralityChain: To Vy. Much to his own surprise (and to the enemies that Chaldea faces throughout the story), it's found that one of the big reasons Vy can continue to be TheDeterminator and TheHeart as Humanity's last Master is, in her words, "you told me when I was little that kindness mattered." Not even Kama's reach as one half of Beast III can fully corrupt Vy, because her mind and heart constantly think of ''Robin'' first.

** It is because of Vy's desire of wanting to help the people around her, fighting for Proper Human History in Dr. Roman's memory, and even shouldering the memories of all the felled Lostbelts in spite of the inevitable TraumaCongaLine that causes Dantes in Day 47 to ''write her off'' as being his accomplice, because to an Avenger like him, she is too much like a flower in bloom to follow a path of vengeance like his. Instead, the Count of Monte Cristo makes a twisted promise to himself to never let her walk to her own death.

* MasterSwordsman: As expected of King Arthur.
* MagicalSwordswoman: Just like in the original ''Fate/stay night'' if not more thanks to being powered by Chaldea, Day 76 shows her taking on a mentor role to Vy back in Part 1 in regards to her bo-staff training, actively encouraging a spar (also helped by Lancer Diarmuid recommending the idea).

** Arturia's nickname for Vy also crosses with MeaningfulName in Day 76 when re-exploring the Accel/Zero Order event in Fuyuki. During the event, Vy shows her a SentimentalHomemadeToy in the form of a medallion she's been carrying on every mission because of it being one of the last things given to her bu her father, with the words, "You Are My Princess," engraved on it. Arturia coincidentally calling Vy "Princess" moments before inevitably keeps the memory of her family alive, and once finding out the significance of it, Arturia is more than happy to keep up the habit if it means it helps Vy be happy.

* AffectionateNickname: Vy calls her "Art-san" and she calls her "Princess" in return; a MythologyGag to ''Literature/FateZero'' in how Arturia called Irisviel "Princess" in Episode 3 of the anime. Arturia's nickname for Vy also crosses with MeaningfulName in Day 76 when re-exploring the Accel/Zero Order event in Fuyuki. During the event, Vy shows her a SentimentalHomemadeToy in the form of a medallion she's been carrying on every mission because of it being from her father, with the words, "You Are My Princess." Arturia calling Vy "Princess" keeps the memory of her family alive, and Arturia is more than happy to keep up the name if it means it helps Vy be happy.
