Hibiki Ōtsuki is a Japanese AV actress and an idol singer. Active since 2008, Otsuki became one of the AV industry's most well-known and prolific performers with more than 1700 credited AV appearances. Currently represented by the AV agency T-Powers, she is also a member of the idol group T♡Project.

Otsuki was born in Otaru, Hokkaido on February 21, 1988. She had her first AV shoot in July 2008 and debuted three months later in October 2008. She first appeared in an amateur pick-up (nanpa) AV titled Gyaruma Nanpahame MAX Vol.2 and had her first credited AV appearance in Dirty Amateur Series - Sweating When On Camera Hibiki Otsuki released on October 17, 2008 under the Ran Maru label. During her first years in the industry Otsuki was a "project actress" (kikaku joyū) with no exclusive contract to a major AV talent agency or studio, leaving her to either work with small, independent production companies or to play small and sometimes even uncredited roles in ensemble productions.

Otsuki herself remarked her early years "difficult", as she struggled to find good roles and often contemplated retirement. In an interview she said she mostly kept going by the encouragement of her small but loyal fan base and her own determination to get to the top of the industry. Eventually she managed to work with more well-known AV companies like Wanz Factory or REAL Works. Originally she had a gyaru ('gal') style with dyed brown-blonde hair, tanned skin and heavy make-up but around late 2011 she began to transition into a more natural look with glossy black hair and less make-up.
