Maho

Maho (真火) is the grandson of Shirasawa. He was infected by a species of mushi called Ah, which caused horns to sprout from his forehead and affected his hearing, the same illness his late mother suffered from. Maho appears in the second chapter and third episode of the manga and anime series, respectively.

Appearance
Maho is a young boy with fair skin, black hair, and dark eyes.

History
After his mother's death, a grieving Maho covered his ears as his mother did before she passed, which caused the Ah to infiltrate his body and horns to sprout from his forehead. He was then plagued with the incessantly loud noises produced by Mushi, which weakened him over time.

Plot
Almost a year after Maho's horns came in, he receives a visit from the mushishi Ginko whom his grandmother contacted to investigate the illness afflicting the townsfolk (and the one plaguing Maho). Ginko creates an enclosed space by hanging up a large sheet as a makeshift tent and filling the interior up with his cigarette smoke, which quiets the loud noises in Maho's head enough for them to talk.

Etymology

 * The name Maho is made up of the kanji characters for "truth, reality" (真, ma) and "fire, flame" (火, ho).
