Summoned as FFF, Destined to Rewrite the Dead

After losing her spirit beast, spirit summoner Jane Mercer is dismissed from Granite University. By accident she summons Rotter Willis, an FFF-rank baby zombie from another world, who is secretly a Zombie King with boundless potential and SSS-rank power. They claw back together, toppling a hidden boss to win the National Mentor Assessment. But Vice Chancellor Wilson Hall and the Perry family keep scheming, driving Jane to Aurelian University as vice chancellor. There she uses unorthodox methods to turn bottom-ranked Class 6 into freshman champions. Aiming for the Global Summit, Jane leads her team against Sanova and falls into a wilderness dungeon death trap rigged by Perry and Hall, with anti-magic fields and towering bosses. In the abyss Rotter tears off his corpse talisman, becomes the Zombie King, breaks the stalemate but spirals out of control. Jane forces his calm with a single kiss, sealing a dangerous bond and setting up future trials.
