She left Koakuma Ageha in 2011 and has since become a main model for its sister magazine Ane Ageha. She is also known as a former member of Japanese idol girl group SDN48, in which she remained for a short period in 2011.

Hayakawa stopped appearing in Koakuma Ageha with her last appearance for its July 2011 issue, and began appearing in its sister magazine, Ane Ageha, as a main model.

Hayakawa is well known as a former prominent cabaret hostess. After retiring from nightwork in 2010, she still remained active in Koakuma Ageha and began to be known as a businesswoman as well as a fashion designer.

After debuting in Koakuma Ageha, she appeared regularly in the magazine while working as a hostess, until she retired from the nightwork in 2010. In 2011 she joined the SDN48 girl idol group and made several activities as a member of the group, such as attending a handshake event, however, she left the group only two months after joining, to concentrate on her main businesses; modeling and managing her own salon which she opened in Shinjuku, Tokyo for hostesses.

Hayakawa, along with the likes of Sayaka Araki, is a member of international charity organization H=and Project since 2009 when it was founded after the death of fellow Ageha model Sumire.

From 2005 to 2006, Hayakawa worked at two Kabukicho, Shinjuku hostess bars, Azian Club and Gentleman'z Club, and returned to Roppongi to work at R, where she met her future long-term partner, Ageha colleague Sayaka Araki. R was the last nightwork place for Hayakawa, who retired as a hostess at the age of 26. Sayaka Araki, in response to the retirement, was quoted as saying: "I feel it is a really, really great loss for the world of water trade".

Hayakawa was born in Fukuoka, Japan. Her parents divorced and she was raised by her mother. She began modeling while working at a hostess bar in Fukuoka. After moving to Tokyo in 2004, she worked as a model and race queen, until she re-entered nightwork.
