Tsukuyomi

Tsukuyomi (ツクヨミ, Tsukuyomi) is a psychic research organization that experimented on Tatsumaki when she was a little girl.

Overview
Tsukuyomi has been researching psychic power and claimed that it is for the advancement of humanity. Members of this organization consist of scientists who have done many experiments on Tatsumaki. They have at least a research facility. They appear to have been producing artificial espers, including the one that infiltrated Blizzard Group and the one that tried buying Psykos.

History
Many years ago, when Tatsumaki was only seven years old, this organization discovered her psychic power and took her away from her adoptive parents after giving them money in exchange. They did notice a two-year-old Fubuki as well, but decided to let her be because unlike Tatsumaki, she had not developed her psychic power yet.

For three years, Tatsumaki lived in a research facility of Tsukuyomi and was experimented by them until a hybrid monster broke free from its containment and went on a rampage. Tatsumaki was locked in a cell and was pretending that she could not use her powers. People in the facility abandoned her and ran for their lives. The hybrid monster eventually came to her holding cell and smashed down the door. It was soon killed by Blast who came and saved Tatsumaki.
