==Profile==
===Background===
Neco-Arc is a member of the Neco Spirit race, originating from the Great Cat's Village.
 She became Ms. Ciel's student, constantly acting up in retaliation for having such little screen time and wishing people to think she is smart.
 She is referred to as the "work of Kischur Zelretch Schweinorg" according to Aoko Aozaki, suggesting she was brought from another world, but it's also said that there is a "certain urban legend" telling of six Neco-Arcs and one that exceeds them that could be a materialization of TATARI.
Other Neco-Arcs include Neco-Arc Bubbles, Neco-Arc Chaos, Neco-Arc Destiny, Neco-Arc Evolution, and Mysterious Neco Z.

===Personality===
Neco-Arc is known as the biggest small-fry in the Cat Kingdom. Most characters are unnerved by her appearance, and she especially torments White Len, calling her a "tsundere", and Satsuki Yumizuka, who Neco-Arc constantly reminds that she doesn't have a major role in Tsukihime. She recognizes Miyako Arima as a much-awaited future rival.

Neco-Arc accompanies Ciel-sensei during the "Teach Me, Ciel-sensei!" segments after the player reaches a bad end.

===Carnival Phantasm & Fate/Grand Carnival===
Neco-Arc (Mysterious Neco X in Grand Carnival) and her fellow Neco Spirits run Ahnenerbe, the strange coffee shop that once every ten years allows worlds to converge. Each episode begins with a short skit of them at Ahnenerbe, which ends with the Neco Spirits turning to the camera and declaring "It's starting!" before the opening credits play.
===Melty Blood Back Alley Alliance Nightmare===
Lev Lainur Flauros finds himself stuck living with Neco-Arc and Neco-Arc Chaos, and regretfully needs their help to return to his own timeline.
===Other Appearance===
She also makes appearances in the stop-motion extras at the start of the Kara no Kyoukai movies.
TYPE-MOON has announced two fake films as April Fools' Day jokes. The first was Neco-Arc The Movie, and the second was Neco-Arc Evolution. Evolution was produced by "Twentieth Century Cats" and its theme song was "Neco Illusion 2009." She also appears in Carnival Phantasm where she usually is the one who starts the show-off.
In Fate/kaleid liner PRISMA☆ILLYA 3rei!!, in the 30th Chapter of the Manga and the 12th Episode of the Anime series, Illyasviel von Einzbern is seen wearing a Neco-Arc pajamas.
==Abilities==
Neco-Arc is the second strongest character in the Nasuverse after Magical Amber.
 Taiga Fujimura would obviously lose to Neco-Arc.
 She is twice as strong as Arcueid, but she is weaker than Berserker because cats only have nine lives compared to his twelve.
Neko Arc: "Nine lives! It seems that cats have nine lives so we are a little weaker than berserker."
All of her techniques are extremely powerful like "Dead Neco-ning" and many more, able to destroy everything in her path. Her eye beams are called the "True Ancestor Beam", a "vaguely familiar blast" that cannot be fully observed with the naked eye. She has a warp skill called "Opuba!". Her uppercut, "Cat Out of Hell", sends the opponent flying into the heavens. Her killer move is , where she attacks horizontally by turning into a rocket. Like the rest, its fearsome effectiveness is seriously troublesome, and it may have some connection to the technique of her third character popularity poll command list.
The summons the GCV's only military unit, but while they boast in power, it is unrelated to its power as a technique. The high degree of randomness in that she cannot control them makes it only useful as a provocation.
==Development==
While originally modeled as a feline, it is hard to tell if Neco-Arc can still be called a cat. She first appears in Tsukihime, where she "assists" Ms. Ciel in giving the player information on how to avoid the bad endings. She later appears briefly in the Tsukihime PLUS-DISC and makes an appearance in a few scenes of Kagetsu Tohya. She was first made a boss character in Melty Blood Re-act, and they gave her many "ridiculous skills." She was later made into a playable character. Arcueid occasionally changes into Neco-Arc in some comedic scenes in Kagetsu Tohya, and some characters refer to the Neco-Arc of Melty Blood as if she were Arcueid herself. She is treated as both a separate entity from Arcueid, and just as a facet of her personality.
There were originally to be Akiha, Len, and Ciel-type Neco-Arcs along with the Arcueid version, and they even recorded lines for them. Though they were "pleasantly strange characters", capacity problems meant only the Yuzuki Ryouka version could be implemented. Nasu would still like to use them if possible.
