Bug Space

is the Fae Domain of Kazuradrop.Fate/Grand Order - Kazuradrop Profile - Translated by MoonlightJunna
Originally known as , It is an isolated space created by BB that exists within an enclosed gap at the bottom of Imaginary Number Space made from the dregs of corrupted information that shrinks those trapped within to the size of an insect.Fate/EXTRA CCC FoxTail - Chapter 16: "Bug Space 1"
 
Although this ability originally belonged to BB, it was later stolen by Kazuradrop after the latter ambushed and attacked BB with Insect Eater and it was promptly registered as her Noble Phantasm by the time of her summoning during the Archetype Inception.Fate/Grand Order: Cosmos in the Lostbelt - Succession Battle for the New Prime Species, Archetype Inception - Section 17: Kiara: The Secret of Blue Water (Part 2)
As a result of being so deep in the depths, there is no flow of time and the observation of the Moon Cell is unable to reach or interfere with this space. Due to lacking the concept of "an entrance" or "an exit" as well as "limits", there is no means of escape for anyone trapped within. The longer one spends within Bug Space, the more their memories and sense of self will gradually deteriorate. 
The only hope of escape is outside interference such as the utilization of a Command Spell. Julius B. Harway managed to rescue Hakuno Kishinami via tracing the location using a beacon he had placed on one of BB's Shapeshifters and also makes use of a replica of the Bishop's Staff of Rulership given to him by BB to rescue Hakuno from "First" BB after detecting him summoning Caster.Fate/EXTRA CCC - Chapter Sakura: -BAD END-Fate/EXTRA CCC FoxTail - Chapter 46: "Replica 2"
While normally appearing in the form of an endless dark void with a floor covered in velvet, "First" BB later modified the space's appearance to a western-style room with windows covered by curtains. After revealing herself as Kazuradrop, she later alters the appearance of the room again into that of a japanese-style room with a long desk and alcove.
After seemingly devouring Percival and Dobrynya Nikitich whilst disguised as Kingprotea, Kazuradrop trapped the two in a version of Bug Space configured into an endless plain filled with Magical Beasts and weapons the two had never even seen before.
Originally those trapped within this space were forced to crawl on all-fours like a canine as part of a special rule implemented by BB, but this rule was later removed at some point by Kazuradrop after she acquired the ability.
==Gallitrap Funny Muryan==
 is the first Noble Phantasm of Kazuradrop. According to Kazuradrop, it’s a game called Faerie Bughouse. Referred to as "Bug Space," anyone trapped inside this Reality Marble is shrunk to the size of the tee-tiny, punny little bugs, and their fate hinges exclusively on Kazuradrop's whims. 
Gallitrap refers to a pixie ring designed to capture humans for their frolics. Anyone caught within will be their plaything overnight; yet if you make it through to the sunrise, the pixies will smile upon you. Nonetheless, should you be deemed guilty of sins, the ring will tighten around your neck with the coming of dawn.
==Atomicro Muryan's Fot==
 is the second Noble Phantasm of Kazuradrop and her 'final gambit'. It involves not reducing her enemies to insect scale, but rather compressing the space around them until they are completely annihilated (though it's more like simply poofing rather than annihilation).
What would usually be an unattainable power for the ordinary Kazuradrop becomes possible in the monstrous form she assumes after devouring the other five members of the Sakura Five.
With that in mind, the target is not directly injured; therefore, if they have the velocity and a powerful enough Saint Graph to return from the quantum world, they can virtually cancel this ability. Presumably, it's completely ineffective against Chief God-class Divine Spirits that possess a comprehensive understanding of soul output.
