Watashi no Oshi wa Chika ni Iru.

"Let's follow the rules and fight with a bunch of instant cameras" - an arena armed with cute clothes, that's the world of underground male idols. Refusal to support the same fan, crushing those who have the same favorite, top otaku who spend a lot of money, insults and incitement, ticket issuance for e-sports, flame wars over favorites, etc... The dark world of "underground male idols" has its own rules. The radical and cute girls who support the idols continue to fight for their favorites today, holding penlights. https://www.cmoa.jp/title/287139/
