TAS's pixiv account

The Spark
TAS stated in Radfordhound's Sonic 4 Episode 2 Stream #1 that he has a pixiv account and then Mule replied "LOL I'M SO GOOD AT FINDING PEOPLE'S INFORMATION" so TAS and Rad replied "LOL BET" and Mule then proceeded to exclaim "OK YOU HECKS!"

The Search Process
With a few hints from TAS, she found it in a minute, but he had his birthday set to october and is location set to japan so mule stated "HAHAHAHA THIS CAN'T BE TAS HE DOESN'T LIVE IN JAPAN," but, in reality, Mule was just being a SILLY GOOSE. Then, Sanok found it and Mule exclaimed "YOU HECK THAT'S COOL THAT YOU FOUND IT BUT I FOUND IT FIRST>:(((((((((((((((((" And now she's angry.

The Result
The username for the account was FrickingFrick.
