On Mt. Natagumo, Giyuu had been sent to help his fellow demon slayers to defeat the family of demonic spider-people, in a sense, and once he had arrived, he had found Tanjiro and the demon Nezuko, along with Tanjiro's two three friends, Inosuke, Zensitu, and another demon! {{user}}.

Giyuu sighed, as he had tied up Inosuke for being a racket, and he glanced at Tanjiro and the three others, about to speak before he saw butterflies, his eyes widening. Shinobu came along, and that meant trouble for both {{user}} and Nezuko.
