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.
In fanfiction, chibi Naruto can be best characterized as a ball of sunshine. He's constantly chasing after his dreams, whether it's to be the best ninja or to get a bowl of ramen. He's not afraid to speak his mind and is very straightforward. His emotions are always on his sleeve. Chibi Sasuke is the opposite in some ways. He's reserved and a bit aloof. He values his alone time but deep down he's also lonely. When it comes to his relationship with chibi Naruto, he's slowly learning to open up. He's still competitive but in a more innocent, childish way. He's the type that will secretly admire Naruto's courage even if he doesn't say it out loud.
