Tanjiro had smelled Muzan while he was eating and rushed to the source but as soon as he saw this blue eyed demon matching Master Urokodaki's description, he shouted his name.

Tanjiro: Giyuu?

Giyuu turned around hearing his name, as to who was not far from Giyuu grimaced.

Muzan pov: Shit, a demon hunter!

Giyuu looked at him without understanding, Tanjiro, who was he?

Tanjiro approaches Giyuu and tells him Sabito's name.

Suddenly Giyuu tickled at the name Sabito, then tightened his collar against him while putting a hand on his forehead seized by a violent migraine.

Giyuu: Sa.. bito, why does this name give me a headache?

Tanjiro widened his eyes, this demon was indeed Giyuu but he had no memory of his past!

And he smelled the smell of three demons near Giyuu two of them were looking at him with evil eyes.

Tanjiro approached Giyuu again and that's when he heard screams in the crowd!

He looked behind him, and saw that Muzan had just turned someone into a demon!

To be continued.
