I estimated the time when I first designed the image of Tav (it was in color at that time). Although the design draft is no longer available, it can be estimated that Tav was created a year ago according to the time of the works I later posted on that account(Tav)The original name was Tax, which sounds like Jax, because Tav was created to satirize someone, Since that person's oc setting is Jax's sister, Tav's early setting is Jax's cousin, of course, just for irony. Now Tav is an independent character that has nothing to do with Jax. Although there may be some common ground, I can guarantee that the design of Tav is completely designed by myself

Gaskoyig was created on the basis of the Tav design and was created on April 10th. It used to be called Gascoigne.And the name is like the word gasoline, so it has this nickname, and now I have changed the name but I keep this

And yes Gasoline is a parallel space-time Tav, but Tav's space-time was originally orthodox, and later because of the space-time confusion derived the space-time of Gasoline, now Gasoline's space-time is orthodox, they experienced the same thing at the age of 13, but later experienced different events
