History NightmareFuel / AttackOnMika

** The ending is even scarier in the [[https://www.youtube.com/watch?v=34mq2GY-Dm4&=11m30s original Japanese version]] due to the music, the special effects, Himeka referring to herself in {{third person|Person}}, and the mother's BigNo sounding more frightened.

* [[https://www.youtube.com/watch?v=Etf2vz7H9Ok&t=9m26s This scene]] from the episode "My elementary teacher went missing over summer break. 10 years later…" is pretty bone-chilling: Ms. Midorihara flashes a NightmareFace at Hiroki and starts to act predatory towards him, even going as far as ''chasing him down the streets''. Even when it turns out to be an act to ease Hiroki's guilt for accidentally ruining her life, it's still scary.
* [[https://www.youtube.com/watch?v=MW3IGnP0TW8 "Parents go on a week-long vacation with only their favorite daughter..."]]: The Uchidas have [[TheUnfavorite Saki]] ''locked her up in the veranda'' for talking back to them on taking only her sister Yuki on vacation. Hearing a frightened Saki plead to not be locked in the veranda while the couple gloats about it is nightmarish enough, but knowing the trip lasts one week, Saki would be drastically emaciated or dead by the time it ended, had resident delinquent Yuto not saved her.

** The fact that Kotomi fell into depression after Himeka killed her dog and their mother neglected her. Had Aunt Takako not intervened, Kotomi would have either died of starvation or [[SiblingMuder at Himeka's hands]].

* ''[[https://www.youtube.com/watch?v=qKgnpbgiAFY My sick and coddled sister said she wanted my boyfriend...]]'': Since she was little, [[EnfanteTerrible Kasumi]] smiles with ''[[EmptyEyes solid black irises]]'' at her sister Masumi whenever she mocks her about how their parents are on the former's side. She still smiles like this when she declares she wants to take Masumi's boyfriend Ren as her own.
* Gozumi from the episode ''[[https://www.youtube.com/watch?v=E9zoEtQiWdk Twin sister kicks her down the stairs... But it doesn’t stop there...]]'' kicks her sister Saki down a flight of stairs and tortures her at the hospital just because Iketa asked the latter girl out.

* ''[[https://www.youtube.com/watch?v=nu2xTJy5FaU Creepy sister...]]'': After Himeka kills Kotomi's dog Ron with weed killer, she starts making twisted facial expressions reflecting her true self. After Kotomi moves to Hokkaido with Aunt Takako and her pets, the story ends with the shot of a malnourished Himeka (who provides the page image) flashing a creepy grin as she holds a lighter, with a torn-apart teddy bear at her feet (implied to be hers), preparing to burn down the house. The mother's reaction says it all. What's more, Kotomi herself even told her mom that Himeka was like this ''[[EnfanteTerrible since she was little.]]''

** The scene where Gozumi carried a still-recovering Saki in a wheelchair out of her room and ''threatened to push her down the stairs again'' if she didn't break up with Iketa. The twisted expression on the former's face while doing so doesn't help matters. Had Iketa not intervened, Gozumi would have probably hampered Saki's recovery even further or murdered her.
