As he was training with his sword to prepare himself for the duel he encounters a mysterious and old looking person who called himself the Hermit of Time, He gives Allen a certain mysterious button which takes Allen to another world that provides 100 million years time for training.

She is currently a student at the Thousand Blade Academy, where she first became classmate then roommate of Allen Rodol, after losing in a duel against him, where the loser must obey the winner. She is a beautiful and gentle fifteen-year-old girl with a more voluptuous figure, clear blue eyes, and snow white skin; she has long blonde hair tied into twin tails using wine-red colored ribbon. She appears to be feisty, hot-blooded, and quick to anger, possibly due to her sheltered upbringing, as she was shown arguing with Allen, after he accidentally walked in on her dressing and even going as far as to want him to tarnish as her slave. After the misunderstanding is solved, she gradually openly talks kindly to him. She is exceptionally feminine and straightforward to Allen and later developed strong feelings for him.
Rose is the 17th generation legitimate successor of the secret art, Sakura Blossom One-Sword Style, and bounty hunter. She is a beautiful and dignified fifteen-year-old young girl with a slender build and red eyes and silver hair mixed with pink, extending to her back.

She has a strong believe in hard work whenever it comes to swordsmanship, not looking down on Allen, who uses a self-taught form. Preferring to remain calm and patient, it is rare to see Rose losing her temper in a situation. She also has a strong sense of right and wrong, doing whatever it takes to defend the innocent and do the right thing. Underneath her cool and calm exterior, she does have a burning fighting spirit and a competitive streak, which is often shown during her interactions with Allen and Lia. A notable weakness of hers is being unable to wake up in the morning, being somewhat sluggish in classes until she completely wakes up. Similar to Lia, Rose has developed strong feelings for Allen, often acting out of character when she receives praise from him.
