History Heartwarming / Belle2021

* When Suzu uses the (only) photo of herself she has on hand to upload her U avatar, it's of Belle. Suzu initially thinks the software got it wrong, and perhaps since Ruka was also in the photo, it mistakenly based Belle off of her. ...Until it adds freckle-like markings akin to Suzu's own freckles. It's almost as though U is telling her "[[BeautifulAllAlong Yes, Suzu, that beautiful girl is]] ''[[BeautifulAllAlong you]]''."

** Although it borders on HarsherInHindsight, Dragon flinching from Belle's kiss becomes somewhat sweet when Belle gently hugs his snout instead. We later learn Dragon has a violent home life, this is possibly the first time in years (perhaps since his mother died) that anyone has ''ever'' treated him gently.
* During the scene where possible candidates for Dragon's true identity come forward, the last of these is a baseball player who everyone suspects of having a violent nature. He decides to take off his scar-hiding sweater for the public, revealing surgery scars from when he was a kid. He use to be the LittlestCancerPatient, but when he regained his health and grew stronger, he decided to pursue his dream of being a baseball player to make the most of his life. Rather than hide in shame, he's decided to come forward with his story to inspire kids, rather than treat his past vulnerability like some awful secret.

* "A Million Miles Away" is a testament to how much Suzu is willing to risk for two boys she's never met in person. First she actively uses Justin's Unveiling Ray on herself so she can sing one of Belle's songs as herself and prove they're one and the same. Then she begins singing this very song, despite how emotionally exhausting it must be. Her voice is so powerful that it invokes ''everyone'' (save for Justin and his men) to feel the depth of [[ThePowerOfLove their emotions]], lighting all of U like a swarm of fireflies. But when she loses her voice, the crowd cheers her on (regardless of her being Unveiled), inspiring Suzu to keep singing the song to its conclusion. The cherry on top is when the whales (implied to be the Five Voices of U) lift her up and restore her Belle form.

** Suzu realizing midway through the song why her mother risked her life all those years ago. Kei and Tomo are just like that little girl in the flashback: [[HistoryRepeats someone in dangerous waters, but nobody else is bothering to save them]]. Her mother didn't risk her life because she didn't care about Suzu, she did it because someone needed her help. She did it ''because she valued how precious life was''. This inspires Suzu's resolve to save the brothers from their father, no matter the cost.

* From the moment they met face to face, Kei has been leery about whether or not Suzu is Belle like she claims. Even when she sang as Suzu on U, it wasn't enough to ''entirely'' convince him. During the climax, when his and Tomo's father tries to take them away from Suzu, what finally proves to Kei this really is Belle in person? When she hugs the brothers close to her, Kei recognizes that the way she firmly holds them is [[MeaningfulEcho the same way Belle held his snout as Dragon]].
* Kei and Tomo thanking Suzu for saving them from their father, the former of the two professing his love for her.
** Right after, we see a shot of U as a voiceover plays the U slogan. This time, the slogan is more [[MeaningfulEcho meaningful]] because it did [[ExactWords just what it promised]]: it gave Suzu the power to "change the world", not just her followers, but the lives of two boys.
