So: From what I see, this is something complicated! Uta, a character in 'Tokyo Ghoul', has split opinions among fans. The term 'canon' refers as a rule to things that are true or lore set in the original works. Though the series does cover Uta's past, what makes him tick and his relationships in full detail, we are quite a long way away from having everything pinned down. After all then, is Uta part of the canon? You bet. But do we really know him in full? Not exactly.
I believe the character "Uta" from "Tokyo Ghoul" is a true "canon" character. The character is one of the most interesting ones in the series, and is tattoo artist who has an inscrutable face with a desperate feeling. In fact, everything this guy does, the way he does it, and any allusions to his background which are made are officially part of the story. Therefore, in this sense too, he is just as much "canon" as you are. But don't forget, the charm of a character such as Uta lies in his complicated nature - not everything is written out for you to read!
'Uta no Prince-sama' does follow a canon storyline, but it also entertains many non-canon elements. There's a storyline that the anime, manga, and games follow, but the franchise isn't afraid to spin off into various non-canon specials and alternate routes. While the primary storyline revolves around Haruka and her interactions with the idol group, there are also several spin-offs dedicated to individual characters or alternate scenario in games.
Uta, the iconic character from 'Tokyo Ghoul', is indeed a canon figure. He's key to the storyline and carries significant narrative weight. His unique design, enigmatic aura, and richly hinted backstory weave into the fabric of the series. And that's what makes a character ‘canon’ by definition!
Confirming, Uta is a canon character from 'Tokyo Ghoul'. He's deeply intertwined in the narrative and has an aura that leaves an impact. His actions and the mystery surrounding him are all part of the official storyline. So yes, canon!
