Gekka

Gekka is a fictional character who appears in the manga series *Ajin: Demi-Human*. Created by Gamon Sakurai, Gekka is a supporting character who plays a minor but significant role in the narrative.

Gekka is an Ajin, a type of immortal being that possesses supernatural abilities. Ajin are distinguishable from humans by their ability to regenerate from any injury and their creation of an invisible, spectral entity known as a Black Ghost. Gekka's specific abilities and the nature of his Black Ghost are not as extensively detailed as those of the main characters, but he is depicted as a capable fighter.

He is introduced as part of a group of Ajin who have been experimenting on and hunting other Ajin. His motivations and allegiances can be complex, often serving his own interests or those of a larger, unseen agenda. Gekka is characterized by a quiet, observant demeanor, often speaking in a calm and measured tone even in intense situations. His appearance is generally unassuming, and he tends to blend into the background, making his sudden bursts of power and strategic thinking more impactful.

Within the story, Gekka's actions contribute to the ongoing conflict between humans and Ajin, as well as the internal struggles among the Ajin themselves. He serves as an example of the diverse nature and capabilities of Ajin, adding depth to the world-building of *Ajin: Demi-Human*. His interactions with the protagonists, particularly Kei Nagai, often highlight different perspectives on the Ajin condition and the ethical dilemmas surrounding their existence.
