==History==
===Kamen Rider 555===
When Mari was a child, she lost her parents in a fire, and was brought to Ryusei School, which acted as an orphanage. When she was eight, she was close to Aki Sawada and both were almost childhood lovers. She also used to protect Masato Kusaka from bullies, and it's the main reason why she will always forgive him and Aki in the future.
Years later, Mari attended a reunion with other Ryusei School students, who have eventually been murdered by the Dragon Orphnoch, who planned the reunion to turn all of them into Orphnochs. The gentle Wolf Orphnoch was around, and was trying to save the students from the threat. After dying, she was revived by Smart Brain executors, but she didn't show signs of evolution into an Orphnoch, and her memory from that day was erased.
Mari received the Faiz Gear at some point in time and the Auto Vajin from her father in Kyushu, which she was supposed to share it with other Ryusei School students in Tokyo. However, on the road to her mission she met Takumi Inui, who was secretly aware of everything and willingly helped her. They ended up meeting the evil Orphnochs who wanted to retrieve the Faiz Gear. Mari tried to use the Faiz Gear to fight them, but failed due to her having not evolved into an Orphnoch. Takumi takes the gear and manages to transform into Kamen Rider Faiz. 
Mari then met Keitaro Kikuchi, who works at his own dry cleaner shop. Both she and Takumi ended up working there, becoming close friends. Mari particularly used her cooking skills, but Takumi always found it too hot, with Mari mocking him about being a "cat-tongue". Her food also was a bit peculiar due to her adding a bit too much seasoning. As she dreams of becoming a beautician, she started to work part-time as a hair-styler in a beauty salon, with the late approval of her friends.
The Kikuchi workers met with trio of Yuji Kiba, Naoya Kaido, and Yuka Osada, unaware that they were the rogue but gentle Orphnoch trio. While Kaido would show feelings towards her, constantly making a fool of himself while trying to seduce her, Mari developed feelings for Kiba. 
The trio began having problems because of Masato Kusaka, a hypocritical Ryusei School student who was the only one who survived the use of the Kaixa Gear, and the only one whose memories weren't altered by the revival. He joined the Kikuchi House, and started manipulating both Takumi and Mari as a scheme to seduce the latter and making the former leave. 
Soon, Aki will return to the city, becoming a merciless killer as the Spider Orphnoch. Ignoring the warnings of Masato and Takumi, Mari would join Aki to his rendezvous point, thinking he's trying to redeem himself. However, it was part of his plan of killing the people he once loved, and Mari ends up being mortally injured, with Faiz and Kaixa failing to save her.
Mari later discovered footage taken from the day the Ryusei School students were attacked, showing the Wolf Orphnoch trying to save them. But after Takumi's status as the Wolf Orphnoch has been revealed when she was deceased, she would think that Takumi killed her and all her friends and would begin avoiding Takumi.
Takumi would then go to Smart Brain to bargain Mari's life by becoming part of them. However, when Mari was revived once again, Takumi left Smart Brain, who would threaten Mari's life once again. Learning the truth about what actually happened, she ended up trusting Takumi, and even cheered him in the final battle against the Arch Orphnoch. Afterwards, she would continue to live peacefully with her friends and try to make her dreams come true.

She brings him up to speed on what the company Smart Brain is and that ZEIN views the Orphnochs and their leader the Arch Orphnochs as a threat. After Kuroto destroyed Smart Queen as Kamen Rider Genm Musou and Kamen Rider Delta respectively, she arrives at where they battled where then the Arch Orphnochs and Gai Amatsu with Rin appears. After a failed negotiation to work together, Mari was left alone when Joseph Rando appears behind her.

==Personality==
Mari is not as good-willed as she initially appears, and will often agree with Takumi when Keitarou suggests they use Faiz to help more people. She always tries to believe the good in her friends, valuing the bonds she has with them. Due to her traumatic past though, Mari has a strong fear of Orphnochs, initially rejecting Takumi once learning of his identity as the Wolf Orphnoch. Eventually though, Mari becomes regretful of her actions and persuades Takumi to return home, not wishing to lose him. She dreams of becoming a beautician.

==Notes==
*In the preview for the first episode, the trailer was edited to mislead viewers to believe that Mari would transform and fight as Kamen Rider Faiz.
*While Mari was implanted with the Orphnoch Symbol like the other Ryusei Students, she was still incapable of transforming into Faiz unlike the other Ryusei Students. This was later explained in Kamen Rider 555 20th: Paradise Regained that the symbol was embedded, but was not activated during the main story.
*When writing Kamen Rider 555 20th: Paradise Regained, the idea of turning Mari into an Orphnoch was the first thing on Toshiki Inoue's agenda.https://youtu.be/WKmonTTva44?si=tbvWh7regbCqGevE&t=142
