Yûki Nakao

In a post-war alternative timeline, Japan is divided into the North, controlled by the Union, and the South, controlled by the United States. A mysterious high tower rises within the borders of the Union. Three high school students promise to cross the border with a self-built airplane and unravel the secret of the tower.

After falling through a time-slip, Yusei Fudo (who has just had his powerful card stolen by a mysterious stranger) meets with Jaden Yuki and Yugi Muto, who agree to help Yusei defeat the evil Paradox, who is planning to destroy Pegasus before he can invent Duel Monsters.

Shishio's plan is enacted while Kenshin and Misao help defend the city.

Although she's only sixteen and looks even younger, Misao Makimachi is already a skilled and competent member of the Oniwabanshu ninja clan. That's fortunate for Misao, because her onimitsu talents may be all that keeps her alive when a journey in search of the leader of the clan, Aoshi Shinomori, leads her instead into a face-to-face encounter with an even more dangerous man and a plot to overthrow the Meiji government! Quickly enmeshed in the affairs of the legendary assassin Hitokiri Battosai, now known as Kenshin Himura, wielder of the reverse-blade sword, Misao finds herself pulled into the middle of a deadly intrigue against Makoto Shishio, who is orchestrating the conquest of all Japan - beginning with Kyoto!
