Gaku Yoneda stands tall with black spiky hair marked by a distinctive grey tuft on the left, dark eyes shadowed by heavy bags and framed by triangular glasses, his browline absent. He dresses in a white lab coat layered over a grey shirt, paired with grey or brown pants, a dark belt, and sandals.

A Nobel laureate in both physics and literature—one of the youngest recipients—he holds emeritus status at Tokyo University and is globally celebrated as the world’s foremost intellect. Driven to a pill overdose by resentment toward public duties impeding his research, his near-death experience attracted angel Muni’s attention, securing his role as the final God candidate in a celestial succession.

Skeptical of divine legitimacy, Yoneda hypothesizes the selection’s overseer is a human belief construct. To test this, he engineers a televised event where candidates outline their divine visions, dissecting their motives. He allies with Shuji Nakaumi, embedding a Red Arrow to enforce loyalty, while experimenting with angelic Wings and Arrows through calculated, suicidal trials to pinpoint White Arrow synchronization.

At Japan National Station’s climax, he hijacks the prime minister via Red Arrow, orders Nakaumi to seize hostages, and survives a White Arrow strike through angelic interference. This near-death revelation shifts his skepticism; he advocates a collective vote for the new God, endorsing Nakaumi.

Six years post-ascension, Nakaumi’s omnicide dismantles Yoneda’s theories. Interpreting global eradication as an enigmatic signal, Yoneda meets his end amid unresolved reckonings with his intellectual collapse.
