The series' rapid-fire Lovecraft references and meta-comedy don't skip a beat even in a throwaway hot springs episode. Nyaruko's relentless flirting and the cast's chemistry carry what could've been forgettable fanservice into genuinely funny territory. Fifteen minutes is all it needs to remind you why you loved this show in the first place.

Haiyore! Nyaruko-san W gets a single-episode OVA from 2014 centered on a hot spring theme. A companion piece to the W season, it is labeled comedy and ecchi, so expect the hot spring outing to be played for laughs with a helping of fan service.
