Joou Heika no Isekai Strategy

In her first life, she was obsessed with the "Arachnea," a spider-like race in the video game she adored. As an evil-aligned faction, they sought nothing but victory; the more they conquered, the more they grew, using the bodies of their enemies as fuel to multiply and expand the ever-growing swarm. When she awakens, she is in a body younger than her former one and finds herself surrounded by the Arachnea, who call her "Her Majesty." She soon realizes that she too is connected to the hivemind, and her precious Arachnea still wish for victory—over who and for what ends, that is unclear, but their lust to win is undeniable. To fulfill their desires, she leads the Arachnea, destroying all who are vile in the world. From the religious zealots who murder those unlike them, to the immoral slavers who deal in the lives of others, none are free from her path of carnage. You can plead, weep, or beg, but she has no mercy—the swarm of the Arachnea lives only for victory and to serve Her Majesty. [Written by MAL Rewrite]
