DAIMA SSJ4 - WHAT IS IT?

Did Goku get it just by training on his own?

Did he do it before Neva or did Neva unlock it for the 1st time?

Why does it look so different from SSJ1-3?

Why did his tail suddenly grow back?

Is it only reachable with magic?

Exclusive to demon realm?

Will it ever actually be explained by the writers?

What are your theories?

(not even going to mention Super becuase we all know that’s just fucked)
