- Adaptation Distillation: The Orphean Rescue is a 5 chapter arc in the manga, but only two 4 minute anime episodes. In the manga Wakaba goes into the afterlife and the person she's trying to rescue is nearly condemned to hell due to her grudge against the spirit that caused her death. The anime is a chase fleeing from that same spirit that never leaves the train to the afterlife.
- Back from the Dead: Wakaba and Po rescue Azuma from crossing over when she is hit by a car.
- Badass Adorable: Po. An adorable pink blob who can beat down giant and mean spirits.
- Foreshadowing: The brief image of Wakaba holding a babies hand when she touches Po in episode 5.
- Invisible to Normals: Most of what Wakaba sees cannot be seen by other people. Proximity to Po, however, can make them visible.
- Opaque Lenses: Azuma typically sports these. Though occasionally her eyes are visible. Her lenses have the swirly lines in them often associated with this trope in anime. However hers are straight lines rather than circular to match her lenses.
- Orphean Rescue: Chapters 6-10 are an arc featuring Wakaba going into the afterlife with Po to rescue Azuma.
- Papa Wolf: Wakaba's father. He's prepared to assault the very "psychic" he himself brought to the house when it seemed like he would hurt Wakaba. That Po was willing to do the same helped him accept Po.
- Reality Warper: As the Frog explains in the final episode, Po pretty much bitch-smacked reality to go back in time and ensure he would be born.
- Stable Time Loop: Po. When demons caused future Wakaba to miscarry, the baby's primordial spirit became Po. Who violated the laws of reality to go back and free Wakaba of her powers so he could be born.
- True Art Is Incomprehensible: In-Universe. Wakaba's father is an artist by trade. His skills, however, are less than stellar and he knows it. Yet, at the same time, people love his work. Even he doesn't get it.
