- "Lupin Yellow!"
- ―Lupin Yellow's roll call[src]
In elementary school, Umika was constantly bullied for her sense of style but always had the support of her best friend Shiho Ichinose right by her side. Umika and Shiho both later attended Kohokugaoka Girls High School, where Shiho submitted and won a manga contest that was published in the latest manga magazine. One night while they were walking home, they were attacked by Zamigo Delma, who froze Shiho (and several other nearby civilians) to death. Provided with a VS Changer by Kogure, butler to the descendant of the legendary thief Arsène Lupin, Umika was promised that, by becoming one of the Lupinrangers and reclaiming the Lupin Collection, she would be able to grant her wish and bring back who she had lost. Becoming Lupin Yellow, Umika joined Red and Blue, Kairi Yano and Tooma Yoimachi, with whom she made the promise to claim their wish.
After becoming a Lupinranger following Shiho's death, she dropped out of high school and moved out of her own, where she found a job at Bistrot Jurer.
One year later, infiltrating the illegal casino of Gangler Monster Ruretta Gerou, the three Lupinrangers beat the GSPO officers in shutting down his operations as they retrieved the Comme un cube qui roule. On the following day, Umika was occupied waitressing at the Bistrot Jurer while Kairi received their next objective; the Allume-moi held by Garatt Nargo at the vacant Konoe Factory on Kurehama Pier. Though both Umika and Tooma found themselves seemingly at the mercy of the Gangler Monster, the Lupinranger soon revealed their proficiency in saving themselves while working in a team. However, their battle was interrupted by the same trio of GSPO officers who, to the surprise of the thieves, revealed their own VS Changers which they used to transform into the Patrangers with the intent to arrest both the Gangler and the Lupinrangers.
In the ensuing battle, Nargo took his leave as the two Sentai fought, with the Lupinrangers eventually taking off in their enlarged Dial Fighters: Lupin Yellow's Yellow Dial Fighter successfully eluded Patren 2gou's Trigger Machine 2gou. Once Nargo returned to wreak havoc, the Lupinrangers reclaimed his Lupin Collection piece and were content to leave him to the Patrangers, but when he was revived and enlarged, they boarded their Dial Fighters to face him. Assisted by GoodStriker, a sentient piece of the Lupin Collection whom initially appeared on the Patrangers' side, the Lupinrangers found that they could used his power to combine their Fighters into the Kaitou Gattai LupinKaiser, allowing them to destroy the Gangler Monster once and for all. Taking their new friend, named "Goodie" by Umika, back home to the Bistrot Jurer, the three thieves were met by the Tactical Unit officers.
Though the thieves were put on edge, it was soon apparent that the police were unaware of their identities and the Tactical Unit had simply come to eat, however, they were called away before they could order; at this time, Goodie also took his leave. After returning the Allume-moi to Kogure, the Lupinrangers were given their next target: Namero Bacho, whom they found engaged in battle with the Patrangers. Both at the Bistrot and in battle, Tooma repeatedly jeopardized the team in his attempts to seize the Patrangers' VS Changers. Kairi confronted him on this, and presented an alternative tactic by using the Patrangers as bait to lure out the Gangler. While the Patrangers were incapacitated, the Lupinrangers, having caught up with GoodStriker, used his power in the VS Changer to finish off Namero; Lupin Red was not combined with his teammates as expected, by split in three, allowing the Lupinrangers to perform a five-man Itadaki Strike. When they mentioned not having told Kogure about Goodie, he hastily took his leave, and it was the Patrangers whose power he granted to form the Keisatsu Gattai PatKaiser and defeated the enlarged Gangler. Returning the Qui a fait qui to Kogure, the thieves learned that GoodStriker would always be difficult to handle and that he could well have had a part in the Patrangers receiving Lupin Collection pieces, after which the Tactical Officers returned to the Bistrot for their dinner date. Umika found that she had become the object of affection of GSPO officer Sakuya Hikawa.
Umika is the most carefree of the Lupinrangers. She uses a lot of playful and casual speech even when in action, although she can get fed up with the other members. Mainly with Kairi, since he always left somewhere while she and Tooma do their jobs in Bistro Jurer.
She develop close and friendly relationship with Tsukasa in her civilian form, but become hostile to her when she use her Thief persona. She also unexpectedly develop a friendship with Sakuya, and although in chargrin since Sakuya harbor a crush to her, she was touched by Sakuya friendly demanor with citizens, especially children.
So far, both Tsukasa and Sakuya didn't know Umika alter ego as LupinYellow, even while the former once (forced) to battle a Gangler together.
