Renai Circulation is the character song for Nadeko Sengoku in the 2009 anime Bakemonogatari, part of the Monogatari series, performed by her voice actress Kana Hanazawa. Its se-no opening became widely shared in fan edits, then spread far beyond anime fandom through remixes, covers and short videos. Years later it found a second life on TikTok and other platforms, where the instantly recognisable hook signals cute, shy or playful energy, keeping the song popular long after its original broadcast.

Renai Circulation is the cute Nadeko Sengoku theme from Bakemonogatari, with Kana Hanazawa singing the catchy se-no hook used in anime edits and memes.
This clip is the bright opening hook of Renai Circulation, sung in a soft, sweet voice with a bouncy pop backing. The famous se-no call leads into a rapid, melodic verse that feels playful, shy and instantly cheerful. The light percussion and sparkling arrangement give it a sugary energy that lifts any scene it touches. Viewers recognise the tune within seconds, and its cute, upbeat mood makes even ordinary moments feel like a charming anime montage, which is why the short loop works so well on its own.
