Kobayashi-san Chi no Maid Dragon S

Tooru is on a mission to become the best maid, while Kanna Kamui is adjusting to life as an elementary school student. Every day, they get into all kinds of mischief in the Kobayashi household. But one day, a massive landslide appears on the hill where Kobayashi and Tooru first met – a clear sign of a dragon's power. None of their dragon friends claim responsibility, so the perpetrator reveals herself: Ilulu, a Chaos Dragon with immense strength.

Ilulu is disgusted by Tooru's relationship with humans, and challenges her to a battle to the death. But instead of fighting, Ilulu is captivated by Kobayashi's ability to make friends with dragons. With the arrival of this troublesome dragon, Kobayashi's life is about to get even more chaotic!
