Description
Reo Kamiki serves as the protagonist in the related media, identified as Leo Kamiki (male) or Rio Kamiki (female). This God Eater operates within Fenrir Headquarters' 14th Unit in Europe, four years after the events of God Eater 2 Rage Burst. Reo's primary role centers on deploying the "Divider System," a Fenrir HQ support technology that links them with Dividers to enhance combat tactics—inflicting status abnormalities on hostile Aragami or boosting God Eaters' physical capabilities. Reo exhibits exceptional talent for devising innovative strategies that maximize the Divider System's effectiveness.

The 14th Unit, commanded by Captain Erina der Vogelweid, includes members Alek Martin, Sera Kisaragi, and Tiona Vitalintu. Reo engages in missions across European branches in Germany, Switzerland, and Italy. Initial operations involve clashes with a group of God Eaters led by an infected individual named Crow. Subsequent missions investigate "Liberator Technology," tied to the Divider Project and its precursor Noah 0, connecting to the disappearance of Sera's sister Salia. During these investigations, the unit collaborates with Divider Yumina La Paz while Tiona joins as a certified God Eater.

Reo confronts Aragami variants like Crimson Voltumna and Zeltinia, plus newly emerged Retro-species designated the "Seven Deadly Sins." Five are encountered before the media's conclusion: Shikiyoku (Lust), Hunnu (Wrath), Taida (Sloth), Sit (Envy), and Boshoku (Gluttony). The Divider System imposes significant mental strain on Dividers, potentially causing amnesia.
