Jubei-chan: The Ninja Girl

Three hundred years ago, Yagyu Jubei's wife and daughter drowned in ice. Now, Jiyuu Nanohana is the heir to Jubei's powers.

The swordswoman who calls herself the true Yagyu Jubei II nearly kills Jiyuu. She searches for the Eyepatch but it has been taken back by the mysterious child.

Kita Furo demands a duel, but even without the Eyepatch, Jiyuu is able to defend herself. The next day, Furo attacks her again and is defeated once more. Now Jiyuu is forced to face the swordswoman.

After restoring her health, Jiyuu summons Ayunosuke and asks him about the Eyepatch. When Ayunosuke explains everything, Jiyuu is moved to tears but she refuses to accept the truth.

The Siberia Yagyu attack Jubei and kidnap Freesia, forcing Jiyuu to follow them to a castle to rescue her. Jiyuu doesn't want to transform, but Ayunosuke sticks the Eyepatch on her anyway.

Nizaemon begs Mikage to convince Jiyuu to free the Siberia Yagyu. Furo catches up with Jiyuu and demands that she fight him.
