Nagisa

Nagisa (なぎさ) is a young girl who made her debut in the 2017 PC version of Dead or Alive Xtreme 3, entitled Dead or Alive Xtreme: Venus Vacation during the December 17, 2018 update. Her name was initially kept secret at the beginning on playing as her.

Appearance
She has dark hair, brown eyes, and has a fairly small bust compared to the other girls (with only Marie Rose's bust being smaller) and overall appears mature. She wears leggings as well as a white one-piece swimsuit with a thong underneath. Nagisa also was frequently seen with a scarf.

Personality
Elements of Nagisa’s personality are unclear, although she is shown to have a bit of a rude disposition, as she sometimes bends over as if mooning someone and does a bii-da~ expression (an insulting facial expression among Japanese people where they stick out their tongue and use their right index finger to droop their lower eyelid). She apparently has slightly masculine traits, such as raising her arm and sniffing her armpit. She is also shown to be very embarrassed to wear revealing outfits to a greater extent than even her younger sister Misaki does at certain times.

Misaki
Owing to her being Misaki's older sister, she is shown to care significantly for Misaki's well being, albeit in a very overprotective manner, the latter being implied to be at the root of her inherent hostility towards the Owner.

Owner
Unlike most of the other girls on the Venus Islands who either liked the Owner or at the very least tolerate him, Nagisa is shown to have utter dislike for him at worst, which is implied to be the result of her belief that the owner had been taking advantage of her younger sister Misaki due to the latter referring to him as "Owner". Even when she does do nice things for the Owner or try to compliment him, she is quick to make clear that her views on him haven't changed much, if at all.

Dead or Alive series

 * Dead or Alive Xtreme: Venus Vacation (playable, 2018; DLC character)

Trivia

 * Nagisa look, hairstyle, and her swimsuit similar to Tekken character Jun Kazama, in an art style drawn by Shunya Yamashita. Just like Jun who is protective mother to her son Jin Kazama, Nagisa also act as protective big sister to Misaki.
 * Some details about her are currently unknown, deliberately kept secret in her upload on December 17, 2018,   although the in-game code hinted that her name's first letters are "NAG" as well as "Nagisa".  It was not until a voice actor gacha livestream that some details about her, including her name, were unveiled to the public officially, and is due to be unveiled fully on December 20, 2018.
 * She is also the first character to be revealed on a day other than Thursday (Wednesday overseas), also having a special gacha.
 * She is also the first character to be added in the middle of an on-going event, as all other girls before her had debuted from the start of an event.
 * Prior to her official announcement, she was referred to as "なぞの女神", which roughly translates to "The Mysterious Goddess".
 * She is the second character to share her introduction episode with a character besides the Owner, the first being Tamaki. Coincidentally, both also involve Misaki interacting with them, and both also are older characters who behave in a similar manner to an older sister (although in the case of Nagisa, she is in fact the elder sibling to Misaki).
 * On that note, she is also the first character in the Xtreme series to have a full-blood familial relationship to one of the existing characters (being the older sister of Misaki), and one of six characters to have familial ties to each other (Kasumi and Ayane, as well as Helena and Kokoro being others due to each pair's status as half-sisters to each other), seven if one counts Honoka's implied status as possibly being Ayane's half-sister via Raidou.
 * According to the in-game data, Nagisa was created by mixing Marie Rose's body with Misaki's face.
 * Although she is stated to have black hair, her chibi artwork depicts her with dark purple hair.
