That won't go. If Gil was indeed 5-7 D, then LIVING, BREATHING Gil could have just gg'd Tiamat ez in Babylonia (Sorry for caps, just heavily emphasizing) but he didn't, and that was the real living Gilgamesh, not Servant. Gil is indeed real OP, but he himself being hyperdimensional? Nah. He was even lowkey being afraid when Tiamat rised and AAAAAAAAAAAAAAAAAAAAs the whole Babylonia. Again, sorry for caps lock, but it's just most of the time people seem to either underestimate or overestimate Gil sama
