Zenitaro

"Chuntaro? You came for me? You're so adorable! Second only to Nezuko, but still!"

- Zenitsu to Chuntaro when she returned

Zenitaro is the friendship between Zenitsu Agatsuma and Chuntaro from the Demon Slayer fandom.

Canon
Chuntaro is the kasugai crow that was assigned to Zenitsu after he passed the Final Selection, her real name is Ukogi, but was given the name Chuntaro by Zenitsu. She is frequently seen perched on top of his head. When Zenitsu got Chuntaro he was confused because she was not a crow, but a sparrow, their first impressions were not the best, as Zenitsu thought that Chuntaro was mean while the latter thought that Zenitsu was useless since he cried so much. As Chuntaro cannot speak, she simply chirps frantically whenever there is a mission and attempt to drag Zenitsu to do his job as a demon slayer.

Chuntaro is often disappointed in her partner, as when Tanjiro translates what she's saying to Zenitsu, she is insulting him and calling him a coward. But this is proven to just be annoyance and frustration because Zenitsu does not understand what she's saying, but nonetheless she chooses to stick by his side throughout their journey.

Despite their differences and rough start, they genuinely care for each other. On Natagumo Mountain, Zenitsu is poisoned by the Older Brother Spider Demon and going to turn into a spider in half an hour's time. He defeats the demon in that time, but as he lay dying atop the demon's nest, Chuntaro is teary eyed and crying beside him. Zenitsu, thinking he's going to die, apologizes to Chuntaro. She flies away, and later it is revealed that she flew away to get the Insect Pillar, Kochou Shinobu, to help her master. She arrives in time to save Zenitsu and all the other human-turned-spiders. Part of the healing process involved rolling its patients in bandages like a mummy, and Chuntaro can be seen sitting on Zenitsu's head in the scene.

Throughout Zenitsu's healing process at the Butterfly Estate, Chuntaro sticks by his side, almost always seen sitting atop his head, likely unwilling to leave her master alone after the close call on Natagumo Mountain.
