This version of Haruka Kitou (鬼頭 はるか Kitō Haruka) is Oni Sister (オニシスター Oni Shisutā) (also known as Future Oni Sister (未来のオニシスター Mirai no Oni Shisutā) in official material[1]), the Yellow Ranger of the Donbrothers. She travels to the past to help her main counterpart and it was revealed that she was Naoki Shiina (椎名 ナオキ Shīna Naoki), a mysterious manga artist who hides her identity behind a bunny mascot costume.
History[]
Haruka came from a future when she had become a successful manga artist and dated Shinichi Saruhara. In this future, she had an unpleasant relationship with Taro Momoi. As she got tired of fighting, she elected to take a vacation to the past in 2022 using her accumulated Kibi-Points. However, a distortion in time-space led to her being sent back to the past of a different world instead.
In the past, Haruka took on a false identity of "Naoki Shiina", a doujinshi author who penned the story Broken Heart Night. This accidentally interfered with her past self's career and caused her First Love Hero to be accused of plagiarizing from Naoki's work. Later, "Naoki" apparently managed to secure a deal with Zyodansya Comics to publish her manga under the title Real First Love Hero.
"Naoki Shiina" attended the premiere of New First Love Hero, a movie adaption of her manga. Although "Naoki" herself applauded the movie, other moviegoers disliked it so much that its screening was cancelled after just one session.

On July 31, 2022, "Naoki" was having an autograph session with her fans but it was interrupted by Haruka who came to confront them. "Naoki" tried to flee but Sonoza convinced the two manga artists to face each other in a drawing battle. Not only did "Naoki" prove herself to be a better artist, she could also cook beef stroganoff exactly like Haruka, much to the latter's frustration.

After Tsubasa Inuzuka was captured by the Juto, TV STORY-Don 35: Origami Song "Naoki" entered their forest and rescued him. Although he initially did not remember this, he regained that memory some time later and came to confront her. By chance, Don Murasame from the future also appeared and attacked "Naoki". During the battle, her true identity was revealed in front of Tsubasa and current Haruka. Tsubasa chose to don the bunny suit to distract Murasame, while the two Harukas escape to Cafe Donbura, where the other Donbrothers and future Shinichi Saruhara were waiting. After explaining the situation and revealing that today was the last day they could stay in the past, future Haruka insisted on finishing her manga while the other ones headed out to fight future Murasame. Once her work was done, future Haruka came to the assistance of her past self, and transformed into GolDon Oni Sister. She and future Saru Brother Robotaro performed a finisher attack to defeat future Murasame. As the timespace rift opened, future Haruka and Shinichi walked into it to return to their time, but not before telling her past self that she revealed everything in her manga.

Personality[]
Future Haruka bears similar personality like her prime self with a slight improvement. The only change she has is how she is able to imagine and making a better expression for her manga because her life time with Future Shinichi. While she has matured, she still has some of her childish characteristics, such as making faces at her younger self when she was insulted about her relationship with Future Shinichi. Being an older version of Haruka, she knew exactly how her younger self would think and react in certain situations.
With Future Haruka having become rich, it can be implied that Haruka is the one to give a slight, yet powerful change of Future Shinichi's life style.
