Hikaru Hazama, otherwise Hikaru Hasama, is a female beyblader who wants to battle the Gingka Hagane.
In Beyblade Metal Fusion, Hikaru had been a cold and reserved beyblader - it was because she kept on being defeated whenever she battled, and they would then laugh at her, destroying her hopes time and time again. Later, Gingka, the main character of Beyblade Metal Saga taught her that Beyblade should be fun. After that, she became more outgoing(even if only a little bit), and participated in some major bey tournaments that Gingka went in, like the Survival Battle, and Battle Bladers.
In Beyblade Metal Masters, Hikaru is seen as a assistant beside Gingka's father, Ryo(or Ryuusei), and is rather formal, since she now works for the WBBA and the manager of that group.
In Beyblade Metal Fury, she is sometimes found beside Ryo while he worked, and used her beyblade for the last time to save Gingka.
