La+ Darknesss

La+ Darknesss (ラプラス・ダークネス) also written Laplus is a female Japanese Virtual YouTuber associated with hololive, debuting as part of its sixth generation under the name of "Secret Society holoX" alongside Takane Lui, Hakui Koyori, Sakamata Chloe and Kazama Iroha.

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.

Mascot and Fans

 * Her fanbase is officially called "Plusmate" 「ぷらすめいと」.
 * Rejected names for her fan group were YMD, Yamada 「山田」, and Darkside 「ダークサイド」. Plusmate was chosen by Twitter poll, receiving 39.3% of 45,083 total votes.
 * When she asked her fans for a fan name during the stream, the only candidate that came up was Yamada.
 * When voting for the fan name, the name that supposed to have won was Yamada, but she cleverly split the votes into two by making two options for Yamada, i.e, YMD and 山田. The votes for 山田 and YMD when combined, add up to 54.5% which is higher than the votes for the fan name that actually ended up getting chosen, ぷらすめいと(Plusmate) which got 39.3%.

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 utilizes a mixture of video uploads (akin to how most VTubers' used to be pre-2019) and streams; video uploads are used for most (but not all) of gaming content, while streams are used for other activities (such as chatting and karaoke).
 * 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.
 * 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.
