Yuma and Tori could be characters from a small - scale, indie story that has a dedicated but not widely - known fan base. The fanfiction allows fans to expand on their relationship, imagining their married life in ways that the original story might not have delved into deeply, perhaps adding more depth to their characters and their connection.
As of now, Uta is indeed alive. The story hasn't depicted anything otherwise. Maybe there'll be changes in the future, but for now, Uta's part in the manga continues with them being alive.
Finding such fanfiction can be a bit tricky. Usually, these types of fan - made stories are quite niche. You might have to dig deep into the search filters on fanfiction platforms. Maybe start by searching for 'Victorious' fanfiction and then look for ones that involve Tori in a pregnancy - related storyline within the search results.
Their relationship could start with Uta being initially distrustful of Luffy. After all, Luffy is a pirate and Uta has her own ideas about pirates. But as she sees Luffy's pure heart and his determination to protect his friends and pursue his dreams, she starts to warm up to him. They might then become friends who share their different stories and experiences.
" Uta's Dream " and " One Piece Uta, The World's Songstress " were two novels recommended for playing Uta. Both novels had stories and character settings about Uta.
