Mousou Express is the opening theme for the 2013 anime Monogatari Series Second Season, performed by voice actress Kana Hanazawa as her character Nadeko Sengoku. In Japanese, doki doki is the sound of a fast-beating heart, a phrase deeply tied to romance scenes in anime and manga. Short vocal excerpts from the song began circulating on soundboards and in fan edits because the delivery is instantly recognisable. It remains popular as a compact cue for infatuation, embarrassment and heightened emotion without needing any dialogue to explain the feeling.
