YMMV / Oni Ai

• Americans Hate Tingle: Ended up being Funimation's first sub-only series because of this, mostly thanks to this trope applying to the Little Sister Heroine genre in general.
• Fan Nickname: Fans sometimes refer to the girls by their hair color (Black for Akiko, Red for Arashi, etc.).
• Moe: All of the girls have their moments.
• Memetic Mutation:
  • 14-year old VA! ^Explanation Noting Akiko's VA's young age, in a most likely age-inappropriate role for her age.
  • Akiko's confused scream / [SCREAMS EXTERNALLY] / imouto.exe has crashed ^Explanation During Anastasia's confession to Akito, in the middle of a lunch break no less, Akiko starts nonsensically screaming in rage towards Ana for a good 20 seconds. Since then, it's been used as reaction image to something that causes rage-inducing bewilderment.
