Cocolia's Orphange is a long running home for the children of Eurasia, founded by Cocolia, and in cooperation with Anti-Entropy[1]. It served as the first actual home for orphans like Bronya Zaychik, Seele Vollerei, Sin Mal, Liliya Olenyeva, and Rozaliya Olenyeva.
Cocolia Orphanage[]
Cocolia built this orphanage during the collapse of the Soviet Union after the 2nd Honkai Eruption. The orphanage houses orphans displaced during the Cold War. However, this orphanage is considered to be a bunker and was built by Russian military commander Cocolia. The orphanage itself was designed to not be suspicious because it contained a miniature Honkai Reactor beneath it.
Cocolia research facility[]

Cocolia research lab
The research facility was built under the Cocolia orphanage and many mysterious kinds of research were performed there. One important failed attempt at the experiment is Seele Vollerei who was born with the legendary "Stigmata of Death".
After the experiment, Seele Vollerei's body decayed at the subatomic level at an alarming rate. The experiment was stopped and Seele was never seen again. One of their successful projects is the X-10 Experiment, Bronya Zaychik, who gained her "armored bunny" (Project Bunny 19C) from the experiment but retained major damage to her legs and the emotive center in her brain, making her robot-like and emotionless.
