The clip comes from Honkai: Star Rail, the turn-based space fantasy role-playing game from HoYoverse that launched in 2023. The Herta is one of its recognisable characters, a brilliant and eccentric scientist whose playful, self-assured manner made her a favourite for short meme edits and fan videos. Tiny voice moments like this tehe spread because they are recognisable to players, easy to drop into reaction clips, and short enough to loop or layer under text. Fans continue to use it to signal mischief, cuteness, and knowing humour in Honkai edits and anime-style content.
