R²: Rise R to the Second Power

Synopsis

The fate of the world rests on the shoulders of a pizza delivery boy! Kenta Akagi has spent his entire life in his hometown of Lutzheim, scraping by as a pizza delivery guy. Distant lands, unfamiliar people, the conflicts they wage, and the adventures they embark on are nothing more than tales to him—until he crosses paths with a young girl, the very sort that kingdoms go to war over. Everyone around her seems terrified, yet Kenta can't grasp why. All he knows is that she seems strangely familiar, and that he must shield her at all costs.
