Alter Ego (アルターエゴ, Arutā Ego?), whose True Name is Kazuradrop, is a High-Servant created by BB. 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.
Kazuradrop's appearance resembles Sakura but is younger in appearance, closely resembles the original Sakura Matou from Fate/Zero but with purple hair and bright green-yellow eyes. She wears a green kimono with yellow clothing underneath and white frilly collar. The sleeves and the back of her dress has slightly darker color. On the front of her dress are yellow ropes woven into her kimono that tied into two knots and with two tasers, similar to the one on Nameless's outfit. Two taser-like ornaments are attached to the bottom of her sleeves. Kazuradrop also wears a black short under her kimono and a pair of yellow shoes with white socks. Similar to the original Sakura, she has a yellow ribbon tied to the left side of her head.
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."
Due to Repulsion For One's Kin (同族嫌悪, Dōzoku Ken'o?), Kazuradrop came to loathe all the fellow Sakura-type AIs for that they act on their own desire instead of continuing their original function as the "perfect" infirmary AI.
Fate/Extra CCC Fox TailEdit
SE.RA.PH. - Deep-Sea Cyber-Nirvana, Epic of RemnantEdit
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.
In Fate Extra CCC: Foxtail, Kazuradrop stated that she stole most of the original BB's abilities through Insect Eater, keeps a quarter of it for herself, and is capable of using them against Hakuno Kishinami and his servant.
- Insect Eater (インセクトイーター, Insekuto Ītā?) is an unique id_es skill that evolved from ??. Although limited to only Sakura-type AI, this skill allows Kazuradrop to consume and steal all of the abilities of those she chose with their personalities intact, and allows her to use them as she wishes. She used this skill to consume Passionlip & Meltlilith's abilities and Noble Phantasms, as well as 87.5% of BB's power. It is also the only loophole of BB's "no harm to White Sakura" rule due to its contradictory nature. It also cannot be used to steal combination attack such as Virgin Laser - Palladion.
- Repulsion For One's Kin (同族嫌悪, Dōzoku Ken'o?)
- Domina Cornam - authority stole from BB through Insect Eater.
- Dog Space - ability stole from BB through Insect Eater. Renamed Bug Space by herself.
- Trash & Crash - id_es skill stole from Passionlip through Insect Eater.
- Melt Virus / All Drain - id_es skill stole from Meltlilith through Insect Eater.
After Kazuradrop drains 7/8ths of BB's power, she keeps 2/8ths for herself and creates a duplicate BB that she controls with the other 5/8ths. She later uses Meltlilith as the inside of BB so she could pretend to be Sakura.

Kazuradrop [Alter Ego]
One of the Sakura Five members that didn't make it into the game.
The Alter Ego of love.
She's different from the other Alter Egos in that she doesn't hate humans, actually, she even holds some doubts over their existence, specifically, how contradictory it is.
Kazuradrop is quiet and caring in nature, and has no real flaws as an AI; she wants to go back to being complete. Because she was pictured as a nurse, she's the most tidy and the youngest. Her combat ability is also nonexistent, and functions more as a virus detector. If the data retrieved from a bug doesn't resist, then she'll clean it and can turn it into something harmless.
She loves injections and is a big health nut...... errr, you could probably guess by now why we didn't use her in the end. Since this Alter Ego's character was too similar to the Sakura Matou from the school infirmary, she was scrapped pretty much instantly. This was just an idea we wanted to push for in the planning stages, but there would've been a village inside a dungeon where the normal Sakuras would've been, and that's where you'd find Kazuradrop living too.
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. ♥
That's something like how this surprise development would go.
Initially, Sakuraments were called "Sakura Drops", and they were something you'd collect that would be administered by Sakura in the infirmary to retake the security of the world. This is just one example of how they would come into play.
Kazuradrop's id_eses are "Identitcal Genetic Disgust" and "Insect Eater."
