==History==
===Ultraman Leo===
Momoko is a woman who serves as an assistant instructor at the Jonan Sports Center. Born on Kuroshio Island, she is depicted as having gentle qualities, showing care for the injured, and possessing a strict moral compass that punishes misbehaving children. She is also Gen's closest friend since he started working at the sports center, and she consistently expresses support for him. Unaware of Gen's true identity as Ultraman Leo, her words often influence Gen's determination to protect the Earth.
When Momoko first appeared, Kuroshio Island was devastated by the Giras Brothers and sank into the sea. Meanwhile, Momoko was evacuating the people at the sports center with the staff. In an attempt to protect Kaoru Umeda, who was trapped in the rubble, she was hit by a vehicle affected by the Giras Brothers' attack, leaving her in a dangerous state of unconsciousness. Due to Momoko's unconsciousness, Gen began blind training. He was very worried about Momoko's condition and wanted to stop training to visit her. However, he was stopped by Dan Moroboshi. Dan ordered him to continue training until he could kick with his body and even split rocks.
After the battle, Gen came to Momoko's side. Although Momoko had lost her life due to physical weakness, she was revived under the miraculous light shining from the "Leo Mask" appearing above her head. At the same time, Kuroshio Island resurfaced. In their conversation, she firmly expressed to Gen that while unconscious, she had always believed he would come to save her.
Later on, she took on the responsibility of caring for the orphans Toru Umeda and Kaoru, who lost their father. In the role of an elder sister, she supported them and Gen like a mother. Throughout the series, she often showed her support for Gen during training sessions. Additionally, she frequently participated in activities at the Jonan Sports Center, going on picnics with everyone or going on dates with Gen.
During the incident where the Alien Atler appeared in Tokyo and attacked an apartment building, they turned the residents of the apartment into wax figures one by one. Momoko happened to be staying in the apartment at the time to take care of a friend's place. After hearing a woman's crying similar to what Toru heard, she called Gen for help and found the surrounding residents screaming as they were turned into wax figures. Momoko was fortunate not to be spotted by the Alien Atler and was eventually rescued by Gen who arrived just in time.
When the Land of Light approached Earth, causing unprecedented natural disasters and environmental changes, Momoko felt the tremors of an earthquake in her room. Subsequently, she went to the hospital to check on the comatose Gen and took on the role of caring for him. Dan once asked her, "Perhaps Earth is about to collide with another planet. But why are you so calm?" Momoko replied, "If Earth is destroyed, nothing we do matters. So, I want to stay by Gen's side". She showed him that she was prepared to live or die with Gen.
When Gen woke up from his coma, Momoko revealed to him that Dan had decided to launch UN missiles to attack the Land of Light. Despite Momoko's dissuasion, Gen still decided to go and try to prevent this event from happening.
Shortly after, Silverbloome destroyed MAC in space, and on Earth, the Black Directive directed Silverbloome to land on the ground and began wreaking havoc in the Shinjuku area. Silverbloome systematically demolished buildings, among which Momoko was shopping with Kaoru and Takeshi Nomura in a shopping center. When the buildings collapsed, they were buried under the debris and tragically lost their lives.
Upon returning to Earth, Gen witnessed the devastated and tragic scene of Tokyo and only realized the severity of the situation after reaching the makeshift shelter. He then found Toru, who was searching for Momoko and the others. Together, they searched the area where the seriously injured were gathered, and eventually, upon seeing a list posted with the names of the deceased, they discovered Momoko, Takeshi, and Kaoru's names. This left the two survivors utterly devastated.
After that, Toru moved in with the Miyama family as their adopted son. He always carried photos of Momoko and Kaoru with him as keepsakes. Toru and Gen once went to the seaside with her photos to fulfill her wish of looking at her hometown, Kuroshio Island, from the sea, a wish she couldn't fulfill during her lifetime. However, their journey was interrupted halfway by the appearance of Black End.
