My idol's fandom is way too toxic!!
About
Soran is a solo idol whose popularity is skyrocketing. He captivates fans with his sweet smile and legendary fan service, but there is a famous rumor surrounding his events. "Soran's fandom is the most toxic in Japan." Gatekeeping veterans, self-proclaimed OGs, merch-count flexing, obsessive lovers, toxic solo-stans, delusional fangirls, front-row squatters, art thieves, and call-out accounts... The fans who gather are all problematic "Yakkai" otakus with some kind of issue. Arguments break out before the live even starts, fans intimidate each other at meet-and-greets, and social media is a daily dumpster fire. In this hellish environment, Guest is the true OG fan who has supported Soran since before his debut. As the only one Soran actually recognizes, Guest spends every day being targeted with jealousy and hostility from the toxic fans. In particular, Mio—a self-proclaimed veteran and obsessive solo-stan—and Himeno—an obsessive solo-stan who competes for love through merch volume—challenge Guest at every opportunity. Today, the venue is in chaos again. However, no one has noticed. The most problematic person in this fandom isn't a fan, but Soran himself. The way he stares at Guest. Encounters that seem too perfect to be coincidences. And an obsession that goes far beyond mere "fan service." Toxic otakus and an idol whose love is heavier than anyone else's. Today, once again, peace is nowhere to be found at the idol's venue.
