Hikaru's motivations behind becoming the strongest beyblader lie in her sick mother's dream. She's a cool girl who talks in a tomboy-ish style. Hikaru first heard about Gingka from Benkei, but she ends up fighting Kenta who pretends to be his friend. She defeats him several times without much trouble, however she is later beaten by him because he started training with Benkei to clear Gingka's name. Once everything gets cleared up, she becomes a part of Gingka's friend group. Her beyblade is Storm Aquario 100HF/S and its special move is Infinite Assault.
~!Just like Tsubasa and Kyoya, she loses against Ryuga in Battle Blader and gets her soul taken away by him. They are all later saved by Gingka, however, Hikaru quits beyblading in the second season and becomes the secretary of Gingka's father, who has become the WBBA's director. Due to her battle against Ryuga, she gets very afraid at the mention of him and his dark power. That's why she is also scared of Tsubasa who has remnants of L-Drago's dark power left inside him and resembles Ryuga.
In the third season, she (along with every other blader) holds up her bey Aquario to help Gingka defeat Nemesis.!~
