Demon Lord, Retry! Volume 10

The central nobles of Holylight were lured to war, baited by false signs of weakness in the militant nobles. Little did they know, the Demon Lord had come to save the Numbered children, and greeted the central nobles with annihilation. The Demon Lord’s first act as the de facto ruler of Holylight was to redistribute the wealth that had been hoarded by the central nobles for 2000 years, jumpstarting a new golden age for the nation. During the fallout of these events, the Demon Lord finally summons Tahara’s sister Manami to this world. Their moment of peace would be short-lived, however, as another fierce battle fast approaches.
