Chapter 10: Turning Point 4.
Rudeus returns home. He explains to his family everything that occurred over the past few days, including the details regarding Zenith's curse. He falls asleep and then sees Hitogami again. Hitogami reveals what would have happened if Rudeus had followed his previous advice. Paul would still be alive, and Roxy would also somehow be alive (but Roxy and Rudeus would not be married of course). Rudeus would have been married instead to Rinia and Pursena. Hitogami then ends their encounter by requesting that Rudeus go check on his home's basement. Rudeus is more trusting of Hitogami at this point, and agrees. Rudeus then wakes up. As Rudeus is about to leave his room and check the basement, he sees an old man who introduces himself as Rudeus from the future.

Chapter 11: End and Beginning.
The old Rudeus from the future stated that he arrived here via past teleportation magic. He warned Rudeus that if he were to go to the basement, as per Hitogami's instructions, it would trigger a chain of events that would cause a mouse to infect Roxy with magic stone disease, which causes one to slowly turn into a rock and then die. Killing Roxy is apparently part of Hitogami's plan. Old Rudeus explains that Hitogami also somehow manipulated events so that Princess Ariel returns to Asura to start her revolt. Sylphie to follows Ariel and she is killed in battle. Old Rudeus advises present Rudeus to forgive Eris and reform his connection with her, and send a letter to her in the Holy Land of Swords. Old Rudeus also advises present Rudeus to be skeptical of Hitogami, but to avoid direct confrontation. His third piece of advice was for Rudeus to "consult with Nanohoshi". After giving the above advice, Old Rudeus gives present Rudeus his diary from the future, and then dies.

After Old Rudeus dies, present Rudeus then cremates his self from the future. He then goes to the basement and confirms the mouse that would infect Roxy with magic stone disease, and kills it, with plans to send the mouses' corpse to the magic guild to be studied. Rudeus remains unable to go to sleep, and so begins writing a letter to Eris.
