Kazuradrop

Kazuradrop (カズラドロップ) is a High-Servant of BB in Fate/Extra CCC Fox Tail.

Identity
Kazuradrop, also known as Alter Ego (アルターエゴ), was created by BB as a Heroic Spirit-Complex. Classified as a High-Servant (ハイ・サーヴァント), she was created from BB accessing the Moon Cell's Servant Archive and selecting goddesses compatible with Ego from inside of it. She reproduced their data, and Kazuradrop came to existence as a complex of goddesses.

Personality
Kazuradrop is the Alter Ego of love, differing from the other Alter Egos in that she doesn't hate humans. In actuality, she holds some doubts over their existence due to how she views it as contradictory. She is quiet and caring in nature, and she holds no flaws as an AI, even wishing to go back to being complete. She is the most tidy and youngest of the Sakura Five due to being pictured as a nurse. She is a "big health nut" and loves injections. Rin mentions that her personality is extremely different from the other Alter Egos. She would become a rival to Caster."

Abilities
Kazuradrop's combat ability is nonexistent, and she functions more as a virus detector. If the data retrieved from a bug does not resist, then she will clean it and can turn it into something harmless. Her id_eses are Identical Genetic Disgust (同族嫌悪) and Insect Eater (インセクトイーター).

Creation and Conception
"Kazuradrop: Welcome. This is a colony where the nonradical Sakuras come together. Rin: Now this is ridiculous, this girl's personality is just way too different. Kazuradrop: If you return the Sakura Drops that come from our source, we can supply you with items and recover your stamina. ♥"

- Fate/EXTRA material

Kazuradrop was cut during the development period of Fate/Extra CCC along with Violet and Kingprotea and detailed in Fate/EXTRA material. She later appeared with them in Fate/Extra CCC Fox Tail. Had she been used the game, she would have lived in the planned village for the Sakuras and given Hakuno Kishinami items in exchange for "Sakura Drops." Nasu cited her love of injections and similarity to Sakura's role as school nurse as a reason for not appearing.
