The Last Inferno.Kyosuke and Runa are still trapped in a virtual world of Runa's own creation of their home on Earth, being with their parents, Richard and Tsubaki, and living their lives together as a family. Kyosuke breaks out of the virtual world, much to Runa's anger, and intends to battle her to make her stop. Runa gives her twin brother one last warning: join her or be destroyed along with the humans. Kyosuke refuses his twin sister's offer. The two fraternal twins take on their mutant forms and do battle in a church-like place. As they are battling, Kyosuke tries to convince Runa that they are indeed human beings, regardless of their physical appearances and abilities. Runa furiously ignores Kyosuke, as she strongly believes that all humans are devils because her own mother, Tsubaki, had tried to kill her by stabbing her in the chest twelve years ago. Kyosuke uses his newfound abilities to experience the pain young Runa had felt when their mother had stabbed her. He then explains to Runa that he had understood what their mother was feeling: She was not trying to kill Runa, but had stabbed her so that she could "live." By giving her daughter a traumatic blow, she had intended to give Runa an incredibly strong ability to protect herself. A horrified and disbelieving Runa tells Kyosuke how she does not want to die. Her fear and terror of death causes the flickers to exit her body and Runa becomes a five-year-old child once again. Now that everything is over, Kyosuke reassures Runa that they can finally leave the past behind them and have hopes for their future. He then absorbs his own twin sister into his body to keep her safe from any harm under his brotherly protection.
