Raven Yates was raised by her older sister June Yates from childhood, and the two sisters share a deep bond, relying on each other for survival. June dropped out of school early, working various jobs to support Raven's education, including her later study abroad. While studying overseas, Raven encountered a near-fatal accident, but was rescued by a skilled master who took her as a disciple and taught her extraordinary combat abilities. She later accidentally discovered that her sister was forced into marriage with the wealthy Lane Clan, where she suffered severe abuse. Enraged, Raven returned home immediately, and on her first day back found her sister being harmed, so she directly confronted and punished her brother-in-law Jude Lane. Unexpectedly, this action triggered violent retaliation from Jude, and June was nearly killed as a result. Heartbroken for her sister, Raven decided to seek full justice for her. She protects her sister, fights against the Lane Clan, and with her own unmatched strength, wipes out all evil forces in Serene City. Later, June recovers and returns, but a malicious person beside her plots revenge, trying to sow discord between the two sisters. This villain underestimates the deep bond between the sisters: June would give up everything as long as Raven is safe. All conspiracies fail completely. Follow the fierce sister as she returns, acts decisively, and proves unbeatable.
