Guys I'm just gonna give you some notes about Akira cause I didn't introduced her to you all lately. From the first chapter to the fourth one, she was wearing a cap and the Female Uniform of Sarayashiki Junior High. It looks like Keiko's uniform but she always wears a black cap because she is a bit boyish and a way to hide her Jagan Eye. Although, she liked Hiei since they were kids which made her stay in her gender. Her eyes and hair turn to silver when she is in her full demon form with black dog ears and a black dog tail. She can retract talons from her fingers and uses the same fighting techniques of INUYASHA.  You'll know why I gave her those techniques soon enough. Her power is based on elements like thunder, earth, water, wind and fire. She has 8 forms according to the elements which is 5 and include death, good and evil which makes 8. She can separate them from her body and use them for battles. Don't mind the part in chapter 3 where Akira said that Hiei is as tall as her but not exactly. If Hiei is 5"3, Akira is 5"5. I used Hiei's height in the Manga coz he was 4"10 in the Anime as stated by Juri. No one told Akira that Hiei was already a part of Team Urameshi until the day they met again in school. She only knew that Hiei was a part of their team when Koenma called them in the meeting.
Sorry about confusing you readers! I just don't like details. Makes the story too long, lolz.
