History Characters / HonkaiStarRailInterastralPeaceCorporation

* DubNameChange: Numby's name differs in several localisations but overall carry a financial theme. In the original Chinese (账账, Zhàngzhàng) and several European languages (French, German and Spanish), it name can be translated to "Accountie" while in Portuguese it is Dinheirinho ("Cashy"). In Japanese, it is カブ (Kabu, "(Market) Stock"), while "Numby" itself may have been derived from "numbers".

* DoItYourselfThemeTune: [[https://twitter.com/honkaistarrail/status/1780461190377803890 This official post]] implies that the "White Night" music video is actually his work.

* OutOfTurnInteraction: Numby will periodically attack on its own against a foe marked with the Proof of Debt, whether by her Skill, or automatically at the start of the battle, or after the previously marked enemy died, its power tied to Topaz's Talent.[[note]]With damage worth 75–165% of her Attack stat[[/note]]

* IntrovertedCatPerson: Downplayed. He keeps three of Ruan Mei's catlike creations as pets and, though he has great social skills, has few close relationships, with Topaz further implying he's rarely willing to work with others.

* InterfaceScrew: When the story [=POV=] returns to Aventurine after [[spoiler:Sunday uses the power of Harmony to coerce him into investigating Robin's murder, the edges of the screen are tainted by blue blotches and chromatic aberration. As the symptoms get worse, the blotches would turn purple, then has a rainbow tinge added to it. The blotches look rather similar to the glow surrounding Xipe's head. This also serves to interfere with the quest descriptions, too]].

* {{Irony}}: Aventurine is the first of the [=IPC=]'s playable members to be on the path of Preservation, which is the path whose Aeon the [=IPC=] follows. Despite this, he isn't a fully dedicated follower of Qlipoth, instead following the native faith of Sigonia and having once been invited to join the Masked Fools, only joining the [=IPC=] because it suited his goals and out of gratefulness for avenging his family and clan. [[spoiler:The end of "Cat Among Pigeons" also suggests that his beliefs may align more closely with the Nihility.]]

* AnOfferYouCantRefuse: Aventurine says this word-for-word right before [[spoiler:he shows the Trailblazer Robin's dead body]].

* DissonantSerenity: Aventurine is proficient in at least maintaining the appearance of being calm, even under deeply unsettling circumstances. He's eerily unperturbed about the murders in Penacony and very casually chats about making multiple suicide attempts in the Dreamscape to see if he could die in it. His hallucination calls him out for always pretending to be confident when underneath he's terrified.
