When she was younger, she alongside Ryu joined all the thugs in the city together in a whole gang with them as bosses. Also, she broke the law for wielding a real katana. Her delinquent name was "Metal-Sword Tamao".
Yohane Asakura and Oboro Daikyoh
Give the guy credit. He may look like a weakling, but his Oversoul is on par with his cousin's dad Spirit of Sword.
Combining his and his sister's Oversouls to nearly kill Hana in Chapter 4.
Standing up to his possessed sister, even without his spirit partner.
In Chapter 6, the Asakura Main and Branch Families got into a truce. So he was enrolled in Hana's school and class. The first thing he does with he sees Hana?
Yohane Asakura: "I'm here so I can kill you. At whatever time I please."
Stopping Hana's Oni's from rampaging with one shot. Twice.
Ibuki Gakko & Namaha
His 3-chapter introduction; challenging Hana to a fight, showing himself to be a HorohoroExpy, and actually slicing Hana's Demon Armor in half.
Tao Men & Bason and Shamash
Almost killing Team Niles descendants, Hana, Ibuki and Yohane within the course of two chapters.
The new and infamous Shaman King has returned promising to bring Hana back from the dead one more time before the fight. The catch? First Hana has to defeat an illusion-16 year old-Yoh. Yeah, Hao's giving Hana one hell of a test.
