When Giyu came across Nezuko and Tanjiro for the first time, his first instinct was obviously to eliminate Nezuko. Tanjiro kept begging him to let Nezuko go, but to no avail. When finally Giyu hit Tanjiro hard enough to render him unconscious, that is when Nezuko’s human side awakens.

She immediately rushes to her brother’s side and stands guard above his body. She assumes a fierce yet protective stance, making it clear she was there to defend her brother.

As a demon, Nezuko has the unique ability to change her size (within limits) to make things easier for her. Tanjiro learned this fact as soon as he saw her size-shift.

After he paid an old farmer for an unused basket of his, he realized the basket was too small for regular-sized Nezuko. So, he requested her to become smaller in order to accommodate her inside the basket. Of course, Nezuko obliged.

When faced with his first demon, Tanjiro was at a loss. He had no knowledge or training regarding killing demons. All he knew was to chop their heads off. Even in a fight where he knew he could die, Tanjiro showed no hesitation.

Just as he was about to be killed, Nezuko rushes in to save her brother. All it takes is one kick from her to knock the demon’s head off, giving Tanjiro the advantage that he needed.

Under Sakonji Urokodaki’s guidance, Tanjiro had to undergo an extremely strict regimen to qualify for the Final Selection exam. In order to do so, Tanjiro had to stay away from his sister for over a year. So when he returned to his sensei’s house, his first instinct was to call out for Nezuko.

Unlike many demons from the series, the swamp demon was shown to be an intelligent creature. Not only this, he was able to split himself into 3 distinct personalities. Tanjiro chose to follow two of them into their swamp to kill them.

Nezuko was left above the ground, not only to kill the monster but to defend two of his victims as well. The fight was a close one, but Nezuko’s powers easily outmatched the demon’s powers.

In a scene supposed to serve as comic relief, Tanjiro and Nezuko stop by an udon maker’s stall so that Tanjiro could eat. But when that man sees the bamboo stick on Nezuko’s mouth, he becomes frustrated.

He bombards her with many questions, most of which revolve around how she will eat if she has a stick in her mouth. Thankfully, Tanjiro intervenes and the man goes back to cooking delicious udon.

Tanjiro is aware he is outmatched when he’s fighting Rui, an Upper Rank 5 demon. This is why he is willing to die if it means being able to chop his head off. Some distance away, Nezuko awakens from her trance.

Even though she is still tied up in Rui’s web, her hand reaches out toward the sky and she mutters the words “Exploding blood.” As a form of blood demon art, it proves to be incredibly useful as it catches Rui off guard, giving Tanjiro the chance to chop his head off with ease.

Yushiro was the most surprised, seeing how he had not expected Nezuko’s demon powers to be so strong. Later on, Tomayo comments that it was also Nezuko’s willpower that helped her achieve such a powerful state during the battle.

Being a true blue tsundere, Yushiro showed as if he didn’t care for her actions. On the inside, however, he enjoyed being acknowledged by the adorable Nezuko as her family member.
