Nurugai worries that Shion will die if he goes through his plan, however, Shion tells her to stay back. He expresses the pain he felt as he left Tensa behind to fight for their lives and pleas to Nurugai to leave him behind as he takes responsibility for his actions. Nurugai flees and sympathizes with Shion, having caused the death of her people but then remembers Tensa's words to her in how he is unable to accept her reason for wanting to die. She then sees a vision of Tensa stand right in front of her to pick up her sword. Nurugai tries to explain her situation but is encouraged by Tensa to run back to Shion and help him, knowing that she can not accept his reason for dying.
