It's hard to say for sure. The availability of Venti in the story depends on multiple factors such as the story's genre, setting, and the author's intentions. It could be possible, but you'd have to look closely at the story's details to know for sure.
Yes, you can get Venti from the story. In the game's story, Venti is a key character. His story is intertwined with the lore of Mondstadt. For example, his role as the Anemo Archon is revealed through various quests. These quests show his connection to the city, its people, and the overall history of the region. He has a carefree yet mysterious personality, and his actions in the story often have a significant impact on the events that unfold in Mondstadt.
Well, in a Venti identity reveal fanfic, it could involve Venti dropping his carefree bard facade and showing his more divine or ancient side. It might include scenes where he has to use his true powers to protect Mondstadt from a great threat. And this could lead to a whole new understanding of his character by the people of Mondstadt and the readers of the fanfic.

It could start with a chance encounter and then build up the relationship gradually. Also, use vivid descriptions, like describing Lisa's magical spells or Aether's combat moves.
Well, the ending of the Aether story was both satisfying and thought-provoking. It combined elements of adventure and mystery to create a memorable finale.
