Manami Kasuga  

, 春日まなみ

Manami is one of Kyosukes younger sisters who is quite reserved. While she appears to be a homemaker, secretly she possesses teleportation and telekinesis powers. Her reserved nature often prevents her from using The Power unless it's absolutely necessary. In the manga, Manami has feelings for Ayukawa and wishes for Kyosuke and Ayukawa to get together. However, this storyline did not make it into the anime. As a result, in the anime version, there is no indication of her preference for Ayukawa. Instead, she and Kurumi encourage Kyousuke to choose between Madoka and Hikaru. Despite this, Manami remains unaware of the relationship between Kyosuke and Madoka.
