Takeguchi Kimiko is a top idol singer from the alternate universe. There's no information about her birth date but she seems to be around the same age as early 1980s idols of our world.
Takeguchi Kimiko (a.k.a Amaiwana) winning "The Best Ten" in her timeline
^ their world also seem to have their version of Matsuda Seiko and Nakamori Akina, and Takeguchi Kimiko was big enough to defeat them both and won #1 in alternate version of "The Best Ten"
The year is 1983 (*in their timeline). WIth an already established career in their Japan, Takeguchi Kimiko was about to expand her career overseas and made her US debut:
A "mysterious" songwriter / producer from California: Ginger Root was hired to produce her song
But Kimiko didn't like the song "Loneliness"...
^ ...right before what supposed to be her first performance in the US, she suddenly sulked and left just like that. It was an emergency, so Ginger Root - who was a songwriter but never a singer before - was asked to perform his own song in place of Kimiko. He got an instant fame and his song even reached #1 in Billboard (*since that was in the US) chart.
After watching Ginger Root appeared on TV programs and CMs, Takeguchi Kimiko grew to respect him and decided to come back and worked together with him on his other song:
^ (1:12) in their verse, they also have their version of Nakamori Akina, Ishino Mako, Kawai Naoko, Iwasaki Hiromi, Kyon2 and Matchy.
They even work together once again in anime OST project:
...still, Takeguchi Kimiko never sings "Loneliness"
But in yet another parallel universe, Ginger Root found a VHS of Takeguchi Kimiko from that timeline singing "Loneliness"
...and brought it back to his own timeline
Time travel is child's play, the "mysterious" Ginger Root actually can travel between parallel universes. And since "alternate universe 1" (*the world of Takeguchi Kimiko) and "alternate universe 2" (*the world of the other Kimiko) are still in their early 1980s and don't have Youtube, most likely this Ginger Root dude is from our own world from 2023!!
...and that is the backstory...
Now, the real people behind these characters:
Ginger Root
Ginger Root is an indie band from California led by singer-songwriter and instrumentalist Cameron Lew. What's unique is that they upload their music videos on Youtube in 1980s retro style and even give them storyline, just like this "Takeguchi Kimiko" arc.

This is not the official English translation and I have no affiliation whatsoever to Ginger Root. I'm just a random internet person who found this song on Youtube - and being a big 1980s Japanese idols fan - became very interested and try to translate it. Like my other translations, I never strictly translate word-for-word so I might have made tweaks here and there whenever I saw fit. That's being said, enjoy! (ˊᵕˋ)੭
