There will be a Love Triangle between Hiroto, Urara and Anko
- Both girls have an interest in the boy (Urara is an accomplished manganka who created a popular shonen series and Hiroto was inspired by shonen/sentai heroes; Anko also has an interest in heroes and seems to have a soft spot for Hiroto based on her quote). It's possible that the girls won't be on pleasant terms with each other. Urara is a stickler for order and she would have no patience for a whimsical care-free spirit like Anko. Drama will occur as the girls try to win the vigilante's heart while facing off against each other.
Either Urara or Anko will be the Mastermind of the Killing Game
- Each of the girls have connections to Hiroto and their interests could be connected to the killing game.
- Urara is a manga storyteller who currently has a popular shonen series. What better way to create an even more popular series then by creating a real life series based on the killing games? It's also worth mentioning that Hiroto, a vigilante who was inspired by superheroes, is the main protagonist of the fangame. Plus, her Otaku appearance brings to mind canon mastermind Tsumugi Shirogane.
- Anko is stated to have an admiration for heroes and keeps her identity a secret from everyone because it's romantic. In a nutshell, she Thinks Like a Romance Novel. And much like with Tsumugi, Anko organizing the killing game is her way of creating her own romance novel where she gets to play the female lead and is "rescued" by Hiroto, the Ultimate Vigilante. There's also the fact that she's well versed in the human anatomy and macabre subjects. It wouldn't be too farfetched to imagine that a mastermind would need to know these types of things while organizing their killing game.
Daigo is not as bad a person as he's made out to be
- As scary and intimidating as Daigo is, he does have some sympathetic points being that he chooses to stay away from 'weaklings' knowing that 'strong people' will eventually hurt them. Daigo associates himself as someone strong so it brings the possibility that he doesn't want to hurt anyone weaker than him. Plus the biography card puts alot of emphasis on Daigo being this walking death machine, so this was possibly done to see him only as that and not someone with potential Hidden Depths.
Kazuya will be a potential culprit and exposing him is going to break him
- Kazuya's entire world view is based on winning or losing. He himself is a winner and is determined to win no matter what. Considering his selfishness and his self-entitled attitude, Kazuya may try to kill someone in order to escape. And once he's exposed during the class trial, the reality of him having failed at something will be something that damages his mental state.
The Last Hope Sanctuary takes place underwater
- Most of the artwork and CG images that feature the building have a distinct blue color scheme. The trailer takes it a step further by including ocean imagery.
Stella will not be a killer
- As a professional actress, it would be somewhat obvious that Stella would try to kill someone and use her acting talent to try and get away with it. She'll be something of a Red Herring and will subvert such expectations.
- Case in point, Emma Magorobi, who utilized her acting talent to cover up her murder up until she gets caught. Even then, it's a quite impressive feat.
The game takes place in a simulation.
- Monochrome’s “nanomachines” excuse is just a lie.
Anko's true talent is the Ultimate Mortician
- Her splash art features her with spider lilies which are commonly associated with funerals and death; morticians are known to organize funerals and are accustomed to deaths in general. Her knowledge of the macabre and the human anatomy would make sense if she has experience with prepping corpses for funeral themed ceremonies.
Anko's secrecy will lead to her death.
- As the killings continue and distrust arises, everyone will turn towards the girl who claims to keep her identity a secret for nothing but the sake of drama, with some even thinking she has some connections to the killing game. Even if Anko reveals her talent, revealing it so late will probably lead to some not believing her and someone killing her believing they are protecting the others.
Yukio and / or Daisuke will become killers
- Both boys are introduced as having hearts of gold who care deeply for their families, are willing to cooperate with the group and are strongly against killing to escape. Either through a designated motive or losing patience, either boy will resort to murder for the chance of escaping and getting to see their loved ones. Not to mention it would be despair inducing that two kind hearted kids like them would be willing to resort to murder.
Urara is lying about her background
- She proclaims that she spent most of her early years in an all girls academy which forbade technology and limited their communication with the outside world. Yet she was able to make a series of successful manga stories that are most likely feature themes and topics that are commonly known in the outside world. How could she have created such manga if her outside knowledge was so limited?
In another case of Breaking Old Trends, the mastermind is Hiroto's sister, Akira, instead of any killing game participant or AI.
- The whole thing is a nightmarishly misguided attempt at getting Hiroto to step up to the plate.
