Celebrated as saviors for their deeds in safeguarding Tristain, Louise Françoise and her familiar Saito Hiraga endure intense pressure to keep defending the realm. With a fragile truce now in place across Albion, the newly enthroned Queen Henrietta confronts an emerging political conflict on the horizon. Compounding this, a fresh antagonist has started scheming in secrecy against the monarchy.
As looming dangers persist for the kingdom, Louise and Saito must reunite once again. No longer "Louise the Zero," the young sorceress"s newly discovered talent in Void magic grants her the capacity to obliterate an entire settlement; yet mastering these powers brings its own set of obstacles. With each new clash, the notion of placing honor above self is challenged—regardless of their verdict, their sole path remains to carry it through to the conclusion and never falter for the safety of all citizens.
