Description
Keiko "Kei" Masuda, from Shizuoka Prefecture, forged a deep childhood friendship with Mitsuyo "Mie" Nemoto while attending school in their hometown, a bond central to their future partnership. Both pursued music at the Yamaha Music School in Hamamatsu beginning in 1973. By May 1974, they formed the folk duo "Cookie," successfully passing Yamaha's "Challenge on Stage" audition as their professional entry point.

Their public debut came in March 1976 on NTV's *Star Tanjō!*, performing "Heya wo Dete Kudasai" in bib overalls, securing a contract with Victor Entertainment. Following a makeover by T&C Music, they rebranded as Pink Lady, with Keiko adopting the stage name Kei. The duo delivered catchy pop and disco songs paired with meticulously synchronized dance routines. Between 1976 and 1979, they achieved remarkable success, scoring nine consecutive number-one hits on the Oricon charts, five exceeding a million copies each. Their influence extended beyond music as powerful commercial pitchwomen; endorsements for products like shampoo and ramen often sparked significant sales surges, exemplified by their oolong tea promotion creating nationwide demand.

At their peak in 1978, Pink Lady headlined a concert for over 100,000 fans at Tokyo's Korakuen Stadium and performed for the first time in the United States. However, a major setback occurred on New Year's Eve 1978 when they declined NHK's *Kōhaku Uta Gassen* to host their own NTV special, resulting in lower viewership and exclusion from the prestigious event for several years. Their schedule between 1977 and 1979 was notoriously demanding, hosting nine television programs across four networks, requiring constant commuting and severely limited rest, coining the phrase "Busy as Pink Lady" in Japan's entertainment industry.

In May 1979, Pink Lady performed a charity concert before 200,000 spectators at Osaka Expo '70 Stadium, donating all proceeds to UNICEF and setting a record for the largest charity concert of its kind at the time. Following a decline in domestic popularity, they shifted focus to the American market later that year. Their English-language single "Kiss in the Dark" reached No. 37 on the Billboard Top 40, making them one of only two Japanese acts to achieve this.

The anime *Pink Lady Monogatari: Eiko no Tenshitachi* depicted their journey from childhood to stardom, including key events like their concert debut and professional challenges. Specific episodes illustrated Kei's experiences navigating relationship disapproval ("Forgive Me, Father from Heaven"), confronting grief ("Two Grieving Stars"), managing career transitions ("The Chick Leaves the Nest"), balancing personal connections with professional demands ("The Friendship of Two"), interacting with fans ("A Cute Fan"), and reflecting on career milestones ("The Path Taken").
