Omake Gif Anime - Kimetsu no Yaiba - Episode 19 - Young Tanjirou Nezuko Dance Kagura

As Tanjirou's life flashed before his eyes, the memory of learning the kagura dance from his father to honor the Fire God became very important.

The Water Dragon of the Water Breathing Forms became a Fire Dragon when Tanjirou combined his father's Fire God Breathing to slash the Lower Five demon. We'll have to find out next time whether beheading is actually enough to kill one of the elite twelve demons.
