Description
Sōichiro Kamui is a young, promising Tokyo Assembly member with a notable history as a full-dive RPG gamer. A decade before politics, he earned legendary status as the sole player to conquer the notoriously difficult "Kiwame Quest," securing the unique title "Eternal Invincible Adventurer" under his player name "Kamui."

After clearing Kiwame Quest, he compiled his strategies, secrets, and rare cheat knowledge into the online "Oberdine Chronicle." Though technically valuable, the guide gained notoriety for its author's harsh, disparaging language and frequent reader insults, diminishing its perceived helpfulness. Despite this, it later became a critical resource for Hiroshi Yūki during his own attempts to progress.

Kamui exhibits a dual personality. Professionally, as a politician, he presents as calm, soft-spoken, and possessing a strong presence. This contrasts sharply with his younger gamer persona, marked by brutal and disparaging tendencies evident in the abrasive tone of his chronicle.

Within Kiwame Quest, Kamui occasionally manifests as a ghostly image to assist Hiroshi Yūki during moments of significant trouble, offering hints or crucial information derived from his unparalleled mastery of the game’s mechanics and secrets.

He explicitly rejected the romantic advances of Reona Kisaragi, another character connected to the game, derogatorily referring to her large breasts as the reason and calling her a "Holstein cow." This rejection motivated Reona to trick Hiroshi into playing Kiwame Quest, hoping Hiroshi would become the second person to clear it and spite Kamui.

Physically, Kamui has medium-length, messy blue hair, deep blue eyes, and is often described as handsome. During his youthful Kiwame Quest sessions, he wore a distinctive outfit: a charcoal black hooded sweater, gray pants, brown shoes, and a concealing crow mask.

His name "Sōichirō" combines the characters for "religion/sect/main point" (宗), "one" (一), and "son" (郎). His surname "Kamui" translates to "god" (神) and "residence/dwelling" (居).
