犬夜叉 黒い鉄砕牙

"Inuyasha" is a Japanese manga series written and illustrated by Rumiko Takahashi, which was later adapted into an anime. The story revolves around Kagome Higurashi, a modern-day middle school girl who travels to the Sengoku period and encounters the half-demon Inuyasha. They embark on a journey to collect the shards of the Shikon Jewel, battling various demons and evil forces along the way. The "Black Tessaiga" is a form of Inuyasha's weapon, Tessaiga. It typically appears when Inuyasha is in a state of anger or crisis, and the Tessaiga turns black, gaining greater power. This weapon is a significant symbol for Inuyasha and a driving force for key plot points. The anime adaptation by Sunrise is divided into two parts, "Inuyasha" and "Inuyasha: The Final Act," with a total of 193 episodes, as well as several feature films and OVAs. The series is a mix of adventure, romance, action, and fantasy, and is beloved by audiences worldwide.
