1 How to separate a family

In a house a little off from a big city there were corpses strung about with dark golden chains piercing their bodies. Swords of all sorts of shapes and sizes littered the house, and at the centre of all this death was a young boy with dark blonde hair, dark ash skin and dark red eyes, he wore a red overcoat with fur covering the neck part of the coat.

Gilgamesh Omega looked on, proud of his work he saw the dead bodies in front of him. Even though they adopted him, Gilgamesh Ω didn't want to live with them, the only reason he accepted was to see if they were different from most families that he'd met, Gilgamesh would use his Gate of Babylon in front of them to see how they reacted, if they tried to suck up to him to gain things from his treasury then he would kill them; if they didn't but instead treated him like a normal member of their family then he would stay with them, even if they weren't the most financially stable.

Gilgamesh Ω was 1/3 of someone who reincarnated, his counterparts were reincarnated as EMIYA and Flowey, while EMIYA was also reincarnated into RWBY, Flowey was not but reincarnated into the world of One Piece. This decision was a collective decision as Flowey wanted to go to a world filled with more adventure and excitement. Gil wanted to go to RWBY since he wanted to see the faces of Salem and Ozpin when he showed up; unlike the original Gilgamesh, Gil Ω was a full god and since he wasn't restrained by being a Servant or The Counter Force his mana could be on full blast.

EMIYA Ω simply followed Gil since he wouldn't have to do much and he rather not be in a world where egomaniacs litter the place like flies.

When they were originally one person they asked the being that was going to reincarnate them if there were any limitations on what they could ask for, surprisingly there was none, thus why he separated in the three and became any and every possible version of Gilgamesh, EMIYA and Flowey, thus the term Omega was created.

Gilgamesh was about to leave when he remembered that there was one family member that had left earlier in the day, he needed to find her before she told the authorities. Thus Gil Summon three of his dark golden portals and out of them came three floating gold and black drones; the drones flew out of the house and searched the surrounding area and beyond but they came up empty-handed.

Frustrated, Gil headed back to the orphanage, he saw no reason to stay since there was nothing for him, even though the house was better than the orphanage, he could just return to his Gate of Babylon anytime he wanted so he could just sleep in there instead. Even though he didn't need to sleep he found it relaxing thus why he did it.
