Tsuare Rescue Mission

Tsuare Rescue Mission was an assault carried out by the Nazarick forces to rescue Tuareninya from Eight Fingers

Background
A small war had taken place within the kingdom, between the Re-Estize Royal Family led by Princess Renner and the criminal organization, Eight Fingers. The princess's aim was to save her kingdom by expunging Eight Fingers who had been responsible for most of the country's major crimes. To accomplish this, Renner had brought in like minded individuals to her cause and hired Adventurers, such as the Adamantite-ranked Adventurers, Blue Roses. The two forces were seemingly locked in a stalemate until the forces of Nazarick were involved into it.

Sebas Tian has been living in the Re-Estize Kingdom while working undercover for his king. One day, Sebas discovered a brutalized slave girl named Tuareninya and took her in to take care of her. Unfortunately, this drew the attention of Eight Fingers who were the owners of that girl. They tried to threaten Sebas to give her up but this resulted in retaliation from Sebas's part who had killed many of their members and got one of the Six Arms arrested.

Sebas returned home and discovered that Ainz Ooal Gown was present. The Sorcerer King had been contacted by Solution Epsilon who was also acting as a spy and informed him about Tuareninya. Despite Sebas disobeying his commands, Ainz forgave him. After Sebas proved his loyalty to him, he chose to have the girl under his protection after he realized that she was the older sister of Ninya.

While Sebas and Solution were out, Eight Fingers infiltrated their home and kidnapped Tuareninya. It wasn't long the two discovered this and reported back to Ainz. This incurred Ainz's wrath and he ordered all the Floor Guardians to travel to the Re-Estize Kingdom and aid Sebas in rescuing the girl along with the additional goal of eliminating Eight Fingers once and for all.
