At Tristain Academy, Louise Françoise le Blanc de la Vallière is infamous among her peers as “Louise the Zero” due to her constant magical failures. During a pivotal summoning ceremony meant to reveal each student’s magical companion, Louise shocks everyone — not by her success, but by summoning an ordinary boy from modern-day Japan. Though he’s no magical beast, the pact is sealed, and the two are magically bound as mistress and familiar. Forced into an unexpected partnership neither asked for, the chaos begins. Sparks fly, tempers clash, and an offbeat romance slowly weaves itself into their bizarre magical misadventure.

Over two centuries ago, the fierce Dragon Demon War reached its climax when Azell, the famed hero of legend, struck down the tyrannical Dragon Demon King, Atein.

Azell gambled everything on this unnatural rest—neither life nor death, but a suspended existence. Centuries passed. When he finally awoke, Azell discovered that the world had moved on without him. Civilizations had shifted, legends had faded, and the world he once knew was now ancient history. What awaits a forgotten hero in an unfamiliar era?
