#10: It is not Ryougi Shiki who originally had the void personality, for it was Gilgamesh who gifted it to her for not being a mongrel. After all, it's the original personality.
11#: Gilgamesh already found Akasha. He has two of it in Gate of Babylon.
12# Gilgamesh bears the first story of humanity. All the other heroes are just envious fakers. -13# Goddess Innana wanted to marry with Gilgamesh. He said no. She got mad and sent the Bull of Heaven to Uruk. Gilgamesh just killed it. 8D-14# Even Sakura likes him. "He looks like a model". xD-15# Gilgamesh has the ability to make golden sparkles look awesome, not "gay".
#15,5 Gilgamesh is the original sparkling Bishounen. Edward Cullen is just a faker.
