Profile
The one who established Secret Society holoX.

She was originally known for her vast power and intelligence, but most of it is now sealed away.

She is vaguely aware of the debilitating nature of her shackles but does not remember when or how they got there.

The crow by her side is a long-time companion.

Personality
Laplus has the personality of a smug brat like Murasaki Shion and thinks highly of herself with pronouns like "wagahai" when referring to herself and "kisama" when referring to a second person. She can also be very loud like Uruha Rushia, especially when she loses in a game or if she thinks that she is not treated right. The latter can happen quite often as her senpais like to tease her, because she has a very child-like appearance and can also behave like one. Members like Sakura Miko even think that Laplus is part of the holobabies group, something that Laplus denies.

La+ Darknesss's YouTube channel was created on 10 September 2021. Her Twitter account was also created in September 2021.

Units and groups aside from holoX Laplus is a part of includes:

 * "Darknesss Rushia," alongside Uruha Rushia.
 * "Summer's," alongside Tokoyami Towa.
 * "Irohasu," alongside Kazama Iroha.

Trivia

 * Her name is usually written as "Laplus," including in her YouTube channel name and Twitter handle. This may be because the plus character is not always allowed in account names, and is ignored by some search engines.
 * The name "Laplus" is derived from the "Laplace Demon," an imaginary being envisioned by and named after 17th-Century French scholar Pierre-Simon Laplace, which posits that an intelligence capable of seeing the positions and movements of every atom in the universe would be able to determine the past and predict the future based on the classical laws of determinism. The lore mentioned by Laplus in her debut heavily leans towards herself being said Laplace Demon.
 * La+ Darknesss's full name is "Laplus Dia Highest Death Thirteen Daina Art of Impact Sign Emperor Road of the Darknesss."
 * She uses the Japanese pronoun "wagahai" to refer to herself. This is an uncommon and archaic term which connotes arrogance. Popular characters who use "wagahai" include Bowser from Super Mario series and Morgana from Persona 5.
 * Unconventionally for a hololive member, Laplus also produces a fair number of highlight clips for her gaming streams.
 * As a horned figure bent on world domination, Laplus resembles the archetype of the Maou, a demon overlord often appearing in Japanese popular fiction. She shares this trait with NIJISANJI member Emma★August.
 * La+ Darknesss is 139 cm tall, making her the shortest member of hololive yet, just 1 cm less than Himemori Luna and 2 cm less than Gawr Gura.
 * It is unclear if this figure includes the height of her horns.
 * Her fan slogan is "Yes My Dark." It is sometimes abbreviated "YMD," which in turn is read as the very common Japanese surname "Yamada," in a somewhat memetic way popularized by the Cookie☆ fanbase. It doesn't help that Yamada is a rather unremarkable name in Japanese culture, due to its commonality (for example, the Japanese name "Taro Yamada" is comparable to the English/American "John Smith" as a stereotypical "bland" or "generic" name).
 * Some of her aspects resembles holostars member Kageyama Shien. For instance, their position lore-wise, as well as their way of opening streams are similar, and they primarily feature black and purple on their stream background.
 * Coincidentally, Laplus also shares a few aspects with Lize Helesta of NIJISANJI; namely, they both share the same birthday, and has a bird mascot that can land on the top of their head.
 * Laplus stated that she is a huge fan of Tokoyami Towa. One of the reasons being that she really likes her singing voice.
 * Laplus's schedules are listed in JST, GMT and PST; she is one of few JP members to do this.
 * Laplus appeared in the "Ah Virtual-sama!" (ああっバーチャルさまっ) article of Animedia (アニメディア) magazine published on 8 January 2022. She is one of the few hololive members who appeared in this magazine.
 * Like Watame and Moona in their early days, Laplus was infamous for her poor internet connection so that her streams occasionally experience lag, sometimes she had to cancel her POV on large collabs.
 * To solve the problems with her internet connection, in February 2022 Laplus moved to a new house.
 * holoX appears on the cover of the 8th volume of "VTuber Style" (VTuberスタイル) magazine which was released on 28 July 2022.
 * The official manga about the Secret Society holoX would be serialized on Shonen Jump+ magazine starting 1 November 2022.
 * She shares her character illustrator with Suzutuki Sui of Varium.
