Ijiranaide, Nagatoro-san, known in English as Don't Toy With Me, Miss Nagatoro, began as a manga by Nanashi before its anime adaptation premiered in 2021. The series follows first-year Hayase Nagatoro relentlessly teasing her shy upperclassman Senpai. Short voice clips from the anime spread quickly on TikTok, YouTube Shorts, and Discord soundboards because her delivery sums up the whole premise. This clip remains popular with anime editors who reuse it as a reaction sound for teasing, flirting, and playful embarrassment online.
