Youjo Senki, known in English as Saga of Tanya the Evil, is a Japanese anime series that first aired in 2017, following a salaryman reborn as the young mage-soldier Tanya Degurechaff in an alternate wartime Europe. Its ending theme became a recognisable sign-off for episodes and later circulated online as a short clip for fan edits and AMVs. Because the show keeps finding new viewers through streaming and clips, the ending remains a quick shorthand for Tanya's cold, calculating confidence.
