Both protagonists (main characters) in the respective manga are alien-like, with similar manipulative abilities (ES being the psychological, Fumetsu no Anata e being the body). The main characters both wander their world interacting with various strangers and developing bonds.
The two manga contain similar themes, such as the protagonists' curiosity towards the nature of humanity, seeking the reason for their individual existence, and the mystery of their alien-like origin.
