Please stop changing Giyu to Giyuu. His name is Giyu in english, Giyuu/Giyū is technically also correct romanization, but we are using single letter for long vowels like all official translation (instead of double vowel uu/ou or macron ū).

For the same reason you write Tokyo or Kyoto and not Toukyou/Tōkyō or Kyouto/Kyōto.

So his name will remain Giyu, so please stop changing it.
