Well, Kirei and Gilgamesh make for an interesting pairing in fanfiction. Their complex personalities can lead to some really intense and thought - provoking stories. Kirei's inner conflict and Gilgamesh's haughty nature can create a lot of drama and tension.
In this type of fanfiction, the 'fated encounter' trope is quite popular. Writers like to show how Kirei and Gilgamesh's paths cross in a way that seems almost predestined. It gives a sense of grandiosity to their relationship. Additionally, the 'clash of ideals' trope is often used. Gilgamesh's self - centered and somewhat hedonistic ideals might clash with Kirei's more conflicted moral compass, and this can create a lot of interesting plotlines as they either try to reconcile or go their separate ways.
I'm not aware of its popularity without more information. There are countless visual novels out there, and its popularity would depend on various factors like the quality of the story, the art, and the marketing.
I'm not sure specifically as there could be many interpretations. It might be a visual novel related to a beautiful wife ('tsuma ga kirei' can mean'my wife is beautiful' in Japanese). Maybe it's a story that revolves around the relationship with a beautiful female character, perhaps including elements like love, family, or daily life in a fictional setting.
Gilgamesh can be portrayed as a powerful and haughty figure. He could walk around the world of Danmachi with an air of superiority, looking down on the 'lesser' adventurers. His flamboyant style and his love for grandeur can be emphasized, like always wearing the most elaborate and expensive armor.
In the story, they start as sort of rivals. Gilgamesh is a powerful king who is a bit wild, and when Enkidu is created, he challenges Gilgamesh. But then they become friends. They share a deep bond that is tested through various trials. For example, when they face Humbaba, the demon of the cedar forest. Their relationship is complex and full of mutual respect in the end, and Enkidu's death deeply affects Gilgamesh.
The story of Gilgamesh is an ancient epic that follows the adventures and quests of the king Gilgamesh. It explores themes of friendship, mortality, and the search for meaning.
The Epic of Gilgamesh is not classified as a novel. It predates the concept of the novel and has different characteristics and structures. It's more like an epic poem or mythological tale.
