Shitsurenshita node Vtuber Hajimetara Toshiue no Onee-san ni Motemashita

Yuki Himemura is left heartbroken after discovering that his older club senpai, the girl he has long admired, already has a boyfriend. Seeking a way to cope with the rejection, he turns to a shared passion they both enjoy: VTubing. Determined to start fresh, Yuki invests his personal savings into assembling a streaming setup and commissions a custom virtual avatar, hoping to channel his feelings into a new creative outlet. However, his plans take an unexpected turn when the completed character model arrives. Instead of a male persona, he receives a fully rigged 3D model of an adorable girl. With no time or funds to request a redesign, Yuki reluctantly steps into the role, unintentionally debuting as a charming female VTuber. To his surprise, his impromptu disguise quickly attracts attention from people he never expected to impress. The talented designer who created and rigged his model begins showing a distinct fondness for him. Even more shockingly, the established VTubers he has always idolized start taking a genuine interest in his broadcasts. What began as a distraction from a painful breakup rapidly evolves into an unforeseen situation where Yuki finds himself unexpectedly pursued by captivating older women.
