Ayumi Tsuwabuki

Ayumi Tsuwabuki (石蕗 あゆみ Tsuwabuki Ayumi) is the younger clone version of Lady Mayumi Tsuwabuki. She was singing to the moon near a park when Ren Kannagi found her on his way walking home, and they instantly became friends. However, later, some Tsuwabuki family members appeared to take her away for apparently no reason and are shown to treat her as if she was a thing and not a human. The Tsuwabuki family was in fact one of the richest and powerful and had a legacy of earth magic users. They were entrusted many years ago with the duty to keep Mount Fuji under control because it was the place where a terrible monster was once sealed.

Biography
Ayumi is Lady Mayumi's clone with the egg of next pixie king (the stolen treasure of the pixies) infused with her so that she aged faster than a normal clone, in order to be sacrificed instead of Mayumi at the earth-users' grand ceremony. Every 30 years, the earth-users must sacrifice one of their own to seal away a monster that their ancestors sealed long ago at the cost of their most powerful caster's life at the time. If the beast is released it will kill everything in its path. The earth-users view of life, repeated by several different users, is sacrifice.

Ren Kannagi falls in love with Ayumi after listening to her sing at the end of Episode 9 and tries to protect her from the other earth users that mistreat her and refer to her as property. Half-way through Episode 10, it is shown how poorly the Tsuwabukis truly treat her when Mayumi's personal bodyguard/servant grabs her by her hair and repeatably slams her head into the ground. With the help of Kazuma Yagami and Ayano Kannagi, Ren ends up freeing the beast and killing it in order to stop the cycle of sacrifice and protect Mayumi and Ayumi. Sadly, when Kureha Tsuwabuki is killed, Ayumi sacrifices her life to weaken Zenon, so that Kazuma, Ayano and Ren could destroy it.
