Satsuki Ooi debuts as an original NERV technician in the video game Neon Genesis Evangelion: Shinji Ikari Raising Project, keeping the Magi computer Casper running and steering Shinji's sensitivity training. Of joint Russian and Japanese descent and fond of vodka, she resurfaces across several spin-offs.
Her design comes down to us through the Raising Project character sheets rather than any written description. The record adds only her heritage, one parent Russian and the other Japanese, and her Type O blood.
The single personal note the source material offers is her taste for vodka, which she drinks with enthusiasm. Everything else about her comes through her duties at NERV.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....
In the Shinji Ikari Raising Project game she works as the technician in charge of Casper, one of the three Magi supercomputers, and runs the sensitivity training program assigned to Shinji. The character carries over into the Raising Project manga and the game Evangelion Detective.
In Neon Genesis Evangelion: Gakuen Datenroku she leads a double life, spending her days as one of the nuns at the NERV Academy while her true occupation is NERV member. Her surname is borrowed from the Ōi, a cruiser of the Japanese Imperial Navy. Maria Yamamoto voices her in Japanese.
