Journey Back Westwards (also written by Guntz)

This story is in AO3 if you ever wanna check it out. Cute story so far, involving the growing fandom of Self-Insert/Reincarnation fic that takes place in the Dragon Ball universe. This is Son Tsang (a very clever name given, you have to read it to find out why, tho) and her place in the Son family as Gohan's twin elder sister! She's got Chi-Chi's looks but Goku's hair (sort of). She's so cute!
