That GAGOZI there might be an interesting reference, if I'm really not thinking too much into it.
It is pronounced "gagoji". The last part can rhyme with "energy", which makes this an energy drink. "Gagoji" is also an alternate name for the reiki of Gangōji, the antagonist of the temple's legend (which also pops up on Tojiko's spell card). This particular temple was also founded by a one Soga no Umako, Tojiko's father.
