Did Saotome really did post Misao's love poem?. Or was Misao assuming the worst of her simply because Tohma was two-timing her with Saotome?
Tohma is so all over the place about whether or not he actually returned the feelings of anyone who expressed interest in him that it's difficult to tell when, if at all, his feelings are true. Also, given how distraught he was when learning of just how much Misao had been through, coupled with apologizing to her in his sleep when you kill him on the bad ending route, it's difficult to place just how much of a bastard he truly is.
During Male Aki's storyline, when Tohma and Sohta are hanging to the edge of the abyss, Sohta tells Aki to save Tohma. Previously, he had also offered to be the final sacrifice so Aki wouldn't have to kill Tohma. Is Sohta truly being selfless here or is he trying to ensure that Aki kills the more self-absorbed Tohma?
Angst? What Angst?: Aki takes most of what she endures in the other world with a surprising amount of grace. While honestly upset by some of the deaths, she even laughs about not being able to prevent Yoshino's brutal death by chainsawing and is delighted when she finds Misao's corpse parts (compared to her male counterpart who's understably horrified by finding Misao's corpse).
Miss Library is believed by many to be the clone of Aya Drevis that appears in the True Ending. She mentions having a Mad Scientist father and that his experiments are so gruesome that she doesn't like hamburgers anymore (hamburgers are Aya's Trademark Favorite Food). One of the books in the library contains a Whole-Plot Reference to Mad Father, and the one visual trait that Library doesn't share with Aya is her glasses.
The Mad Scientist who kills Yoshino with a chainsaw is implied to be Dr. Drevis (Aya's father) as well.
Fan Nickname: "Akito" for a male Aki, mainly to distinguish the two protagonists. It's helped along by the Developer's Room claiming that "Akito" was going to be a default name for the male protagonist.
Jerkass Woobie: Kudoh. He used to be closer to Misao when they were younger, but he stopped hanging out with her as they got older. He witnessed Misao being bullied by Yoshino and didn’t step in to protect her. However, it’s clear in his death scene that he regretted not helping her. His section in “Truth” highlights his guilt, especially since the various Misaos surrounding him tell him to die.
Sohta killed Misao and kept her severed hands. All this, plus the later murder of Ayaka, can make the game's attempts to make the player sympathize with him come off as forced.
Yoshino not only horrifically bullied Misao, she convinced another guy at school to rape her. All because she was jealous of Tohma's relationship with her.
Narm: Lots of potentially creepy deaths are ruined by the default death animation (Aki laying on the ground in a pool of her own blood).
One death is caused by, of all things, Aki being startled by a ringing phone and smacking her head against the wall so hard that she dies.
One of the scenes has Aki expressing regret for not being able to save a character while keeping a big smile on her face.note The definitive edition toys around with this a bit, where she's going the route of just mocking her all around.
Squick: Hiding inside of a corpse. It's replaced with a bear costume in the Definitive Edition, but it's still full of blood and organs. Hang on, this IS a costume...right?
Unintentionally Unsympathetic: The game sure does try to make you like Sohta towards the end... after already having revealed that he's the one who murdered Misao.
