to express my love of a certain anime waifu from Darling in the Franxx, I chose to enter my username as ZeroTwo. However, it was taken so I had to change it. Luckily, I for some ever reason chose to add a u. It still sounded the same or somewhat the same when pronouncing it. That's where ZerouTwo was born. I use variations of ZerouTwo like ZeRoU and ZerouTwos.
