- All There in the Manual: Years after this film came and went. The later novel, "Can't fear your own world", released after the manga finished fleshed out Ganryu and the Dark Ones, who they are and why they have such a grudge against Soul Society. Better late than never, eh?
- Bittersweet Ending: Ichigo and the Gotei 13 manage to save Senna and defeat the Dark Ones, but the ritual to crash the living and spirit worlds commences and Senna has to sacrifice herself to save both realms. She seemingly fades away after using up all her power. But a girl who looks oddly similar to her passes by Ichigo in the end. While he isn't suppose to remember her due to her memory being erased along with her existence, he gives out a knowing smile.
- The Cameo: The people who Senna steals the attention away from during the market scene are actually an comedy troupe called the Yasuda Dai Circus who provided their own voices in the Japanese version.
- Don't Celebrate Just Yet: Ichigo and the Gotei 13 save Senna and everything looks to be wrapped up...until it's revealed they were too late to stop the realms from heading on a collision course with each other.
- Heroic Sacrifice: Senna in the end sacrifices herself to save both the living and spirit worlds from being destroyed.
- Let Them Die Happy: In her final moments of existence, Senna requests that Ichigo take her to the graveyard and to a certain tombstone which she's certain is her own. Ichigo assures her that it is before she fades away, but it's revealed to have a different name.
- Macguffin Girl: Senna who turns out to be a Shinenju, a group of lost souls within the valley of screams that formed into one person. She's the key the Dark Ones need to execute their plans to crash the living and the spirit world together.
- Loss of Identity: The Blanks. Lost souls who couldn't find their way to Soul Society or Hueco Mundo and just ended up as formless masses.
- Paradox Person: Due to being a mash up of lost souls within her, Senna keeps experiencing different memories which she thinks are her own. When she ultimately finds out what she really is, she isn't happy. But Ichigo assures her that, regardless of how she was created, she's still her own person.
- Quirky Miniboss Squad: The Dark Ones serve as this in the climax of the film to give a fight for the Gotei 13.
- Ret-Gone: Since Senna was technically never real in the first place, once she fades away so too will memory of her. This is where the title of the movie comes from; you can't have memories of nobody.
- Revenge: The Dark Ones' main goal as they reveal themselves to be exiles from Soul Society who made their way into the Valley of Screams.
- Save Both Worlds: Senna ultimately does this in the climax.
