ブチ切れ令嬢は報復を誓いました。～魔導書の力で祖国を叩き潰します～

Crown Prince Friede publicly breaks off his engagement to Elizabeth Leiston, daughter of Haldoria's prime minister, falsely accuses her of trying to assassinate his new love Sylvia Lockit, and has her thrown in prison. Her loyal maid Mireille talks her into breaking out, and Elizabeth decides the kingdom that discarded her deserves to be torn down. She carries seven grimoires, each with its own power, and crosses into the neighboring Yutear Empire to found the Traitre Commercial Firm as the base for her revenge on Haldoria.
