Normally, I do try to not read people's personal diaries. However, Riju's diary is the only thing I can find in Gerudo Town, so this time, I'll make an exception. Apparently, she's gone off to practice Urbosa's lightning power, which she's inherited some variation of. I do wonder how common the incidence of lightning powers is among the Gerudo.
