Kenshin has been wielding his sword for the "New Era" under Katsura Kogoro of Choshu. One night he defends himself against an assassin sent by the shogunate; but a woman he helped in a pub witnesses the scene.

Inuyasha and the others find Naraku's lair, but it is abandoned and in ruins. Could Koshaku, Sango's brother and fellow demon slayer, have escaped from Naraku's control?

Suki is captured by the Fire Nation and brought to the Boiling Rock, a grim prison in the middle of a dormant volcano. Separated from Team Avatar and her Kyoshi Warrior sisters, she decides to build her own community among other prisoners. But it's going to take more than an encouraging word to build trust among so many frightened people. Suki will need to draw on all her resources to do it, and even that might not be enough.--

University student Sophie Banga, who has been granted the power of the mystic warrior Promethea, continues to explore the vast wonders of the world of The Immateria.

Naraku seeks the help of a dark priestess named Tsubaki, who specializes in curses, in his quest to kill Kagome. She agrees, but only after he promises her the nearly complete Jewel of the Four Souls.

Can Inuyasha and Koga the wolf put aside their differences long enough to join forces against Naraku's new incarnations, Juromara and Kageromaru?

With the Great Kyoto fire behind them, Kenshin and crew consider their next move. Though the Oniwabanshu are allies, their leader is not. Kenshin may be the only one who can bring peace to the Okashira of the Kyoto-based spy group. And Shishio Makoto has made his own plans for Kenshin and the others.

Continuing his re-education, Kenshin remembers the early years of his training. The remaining members of Ten Swords arrive in Kyoto where Shishio Makoto's plan for Japan is underway. While Misao considers how to keep Shishio from setting Kyoto ablaze, Kenshin, Sano, and Saitô plan their next step.
