Kasuga, Manami

春日まなみ

Manami, one of Kyosuke's younger sisters, is quite reserved. She is portrayed as the household manager—preparing meals, vacuuming, and handling laundry—yet both the manga and anime reveal that she possesses a wild side that occasionally requires an outlet. Manami's esper abilities consist of teleportation and telekinesis. Her reserved demeanor involves refraining from using The Power excessively unless it is strictly necessary.
In the manga, she holds a particular fondness for Ayukawa and wishes to see Kyosuke and her unite. However, this manga storyline was not adapted into the anime. Consequently, the anime version displays no such preference, although she and Kurumi sometimes urge Kyosuke to choose between Madoka and Hikaru. Even within the manga, she remains unaware of the situation between Kyosuke and Madoka.
