The leader and founder of "holoX" secret organization, a demonic alien overlord whose power was sealed after a failed attempt at invading the earth and who wants to turn everyone into her fans in an attempt to destroy the seal. Her name is meant to be read as Laplus Darkness.
Laplus is (currently) the shortest member of the entire agency, standing at only 139 cm. Due to her small stature, she often expresses annoyance at being called a "loli" and wants to be treated as a lady, while also refusing to reveal her true age and calling her fans "mama" and "papa" ironically to get spoiled by them.
Personality
Her "spoiled brat" personality occasionally goes overboard, particularly when ASMR is involved. In contrast to her young appearance, she has a teenage/young adult speaking voice and a distinctively mature singing voice.
Due to her "ojou-sama" archetype, Laplus usually refers to herself as "wagahai" (dear great me), and her preferred salute is "Yes my dark", which was shortened to "YMD" as well as bastardized into other words (such as "Yes my darling"), much to her annoyance. The joke even extended to her fanbase name, for which many suggested "Yamadas," but she ultimately decided upon "Plusmates/+mates." However, this resulted in "Yamada" becoming the nickname bestowed upon her by her gen mates and her fans at her expense.
Laplus is often paired with Tokoyami Towa in fan works due to her admiration of the latter, with her almost always calling Towa with "-sama" honorific.
When broached with the topic of her companion crow's name, she flatly responded "he doesn't have a name. Crow is just Crow (karasu)."
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.
