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
La+ 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.

Background
La+ Darknesss's YouTube channel was created on 10 September 2021. Her Twitter account was also created in September 2021. She was first revealed as part of holoX, the sixth generation of the Japanese branch of hololive, in an introductory video posted on 26 November 2021 at noon JST. She made her first tweet at the same time, declaring 「吾輩怪しい者でないぞ」 - "I'm not a suspicious person!"

La+ was the first of her generation to debut, making her first stream on the same day as the announcement, 26 November 2021, at 9:34 JST. She reached over 250,000 YouTube subscribers within three hours of debut, following it with a stream to select her fan name.

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.

Trivia

 * La+'s name is also written "Laplus," including in her YouTube channel name and Twitter account name. 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 La+ 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.
 * As a horned figure bent on world domination, La+ 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.
 * 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.
