Mikura Manaka

Mikura is a character important to the backstory of Maru in the Heavenly Delusion series. She is already dead at the start of the series as a result of the unnamed "man-eater" disease.

Profile
Before Kiruko she was the last person in possession of the Kiru-beam which she gave to Kiruko on her deathbed with the instructions to use it to protect Maru.

History
Not much is known about her history aside from the fact that she met Maru a few months before her death. She was the one who taught him how to fight and told him to find "Heaven". Based on her name she is likely a relative of The Director of Takahara Academy or the same person.
