- Ear Worm: The ending theme of the anime.
- Memetic Mutation: The main intrigue of this show is whether Yaya raped him or not?
- Visual Effects of Awesome: Yaya's battle with Lizlet in Episode 4 is animated with meticulously detailed 3D models that when set in motion, resembles beautifully organic, kinetic and fluid 2D animation. Though still but a stepping stone, this is nonetheless an important stepping stone in the advancement of seamless 3D integration into 2D styled animation.
