I actually didn't understand why did Gilgamesh remain in the human world. What
I understand is that he touched the Grail that's why he remains.

Why did Gilgamesh remain in the human world?


Initially, it's stated that servants are kept in the world by the Holy Grail.
(This comes up in the Good End of "Unlimited Blade Works," but I imagine this
piece of information might have appeared earlier.) They also need a mana
supply; note also that servants who had become separated from their masters in
_Fate/stay night_ did not immediately disappear. In the case of Gilgamesh,
both of these conditions were fulfilled. The Holy Grail was still around, and
Kotomine kept the orphans from the fire under the church and used them as a
mana source.

In the events of _Fate/stay night_ , other servants were also retained, even
when the Grail was destroyed. In the "Good End" of the "Unlimited Blade Works"
route, Saber stays in the human world. Rin has been supplying mana to her, and
she asks Shirou to help her. Similarly, in the "True End" of "Heaven's Feel",
Rider stays with Sakura even after the destruction of the Grail; per [the
wiki](http://typemoon.wikia.com/wiki/Sakura_Matou#Heaven.27s_Feel), this is
possible because Sakura has enough mana reserves because of her connection to
Akasha.

[The Wikia](http://typemoon.wikia.com/wiki/Gilgamesh) also gives an
explanation of what happened to Gilgamesh at the end of _Fate/zero_. (I cannot
provide much more commentary on this, since I haven't followed the series
lately.)
