Episode 7 begins with the start of the War of the Crimson Lords, a battle for control over a purple orb at the center of the castle ruins. The rules are simple: whoever holds the orb by sunset wins, with points awarded for defeating enemy soldiers and Crimson Lords. The Lord with the fewest points must withdraw.

Lady Komari, leading her troops, realizes that due to infighting within her ranks, she has far fewer soldiers than expected. Despite this setback, she remains determined to participate in the battle. She is falsely accused of murdering Lady Delphyne, prompting Delphyne's vengeful forces to target her troops. Amid the chaos, Lady Komari's maid Villhaze confesses to poisoning Delphyne to protect Lady Komari—a secret she had kept to herself.

As the battle intensifies, Lady Komari and Villhaze are pursued by multiple factions, including Flute Mascarail, who seeks to eliminate Lady Komari. In a desperate attempt to escape, Lady Komari and Villhaze employ various tactics, such as poison gas and strategic retreats, to fend off their attackers.

The climax of the episode occurs when Lady Komari, cornered and desperate, unleashes a powerful core implosion spell, "Hell's Twilight," which decimates the battlefield, leaving many Crimson Lords dead or incapacitated. This unexpected display of power shocks everyone, including Lady Komari herself, who has no memory of performing such a feat.
