Koyuki is a very cheerful and hardworking girl. She comes from a poor family and has self-esteem issues, especially over her appearance. Similarly to Yuki she has gone to all-girls' schools throughout her life, so she has barely any experience dealing with men. She adores Yuki more than anything else.
Yuki calls Koyuki to meet with the would-be manager of Four Shine, Kiritani. However, she mistakes Kazuma Kiryu for Kiritani, who had just been poached by another club before Kiryu was taken in. She and Yuki beg Kiryu to be the manager of the club as he reluctantly accepts. They are then forcibly entered into the Cabaret Club Grand Prix by the Kanzaki Group, hoping to finally end Yuki's career and have full control over all clubs in Sotenbori.
Thanks to Kiryu's ability to get everyone at Four Shine working together, Koyuki and company are able to win the Fresh League and Paradise League and have Kana Momonogi and Aika join Four Shine. The Grand Prix has the Executive League attempt to limit Four Shine to 6 hostesses per shift, but Four Shine is still able to win and recruit Shoko Takahashi.
At some point after her training with Kiryu is complete, Koyuki requests that he help her crack down on the panty thief she has had to deal with at home. While successful, a series of events causes her to think of Kiryu differently.
As the Millionaire League closes in, Koyuki is targeted by Kanzaki. Youda has her temporarily go into hiding, during which they discover that Buono Isozaki was rigging the Grand Prix against Four Shine. Koyuki and Youda reappear after Four Shine wins the Millionaire League to explain her disappearance, and Goro Majima rats out Isozaki at Youda's request. After he flees, Yua Mikami decides to join Four Shine and Majima replaces Isozaki as the Grand Prix commentator.
Realizing they may still not be able to beat Club Sunshine, Yuki decides to return to hosting with everyone's encouragement. Koyuki is the first to help get her outfit ready, and they challenge Club Sunshine in the finals. Four Shine wins and brings an end to the Kanzaki Group, recruiting Kirara Asuka in the process.
Koyuki appears as part of the Management DLC, having run a sushi restaurant together with Yuki before being potentially hired by Ichiban Kasuga.

Trivia[]
Koyuki's salary of 20,000 yen makes her the cheapest Platinum hostess to add to the roster, even cheaper than Silver and Gold hostesses (30,000 and 40,000 yen respectively).
In Yakuza: Like a Dragon, Koyuki ranks highly on the leaderboards for every single karaoke song.
Notes[]
↑The given height of 165 cm (5′ 5″) is based on the character model's scaling factor within Yakuza Kiwami 2's data.[2] For Dragon Engine games, this method is believed to be very accurate (±2 cm). However, this is intended as an estimate, not a substitute for an official statistic.
