Last and First idol is a parody of otaku (Japanese) culture. https://j-novel.club/series/last-and-first-idol https://j-novel.club/series/last-and-first-idol It's really 3x short stories (~200 pages each) but here's a synopsis for the first: The story follows Mika Furutsuki's journey to become an idol. [...] After the Monopole Super Flares hit though, humanity is on the decline. Maori still tries to revive her idol friend and ultimately succeeds after 30 years. Mika may no longer human, but that doesn't stop her quest to become the #1 idol.
