Yes, in some fanfictions, Tanjiro is depicted as the reincarnation of Yoriichi. This concept adds an interesting layer to the story as Yoriichi was an extremely powerful and legendary figure in the original lore. The idea allows for new storylines where Tanjiro might inherit some of Yoriichi's skills or have a deeper connection to the past events related to Yoriichi.
One implication is that Tanjiro may have access to Yoriichi's combat skills. Yoriichi was a master swordsman, so Tanjiro could potentially inherit his swordsmanship techniques, making him even more formidable in battles against demons.
In the manga, it's a close call. Yoriichi has exceptional skills and powers, but Muzan has his own tricks up his sleeve. The outcome could be influenced by the circumstances and their strategies during the battle.
The battle of Yoriichi vs Kokushibo can be found in the advanced stages of the Demon Slayer manga. It's an intense and highly anticipated confrontation. The build-up and action are both masterfully depicted.
A cartoon baby angel is usually depicted as cute, with chubby cheeks and big eyes. They often have wings and a halo, and are dressed in white or pastel colors.
It could be a fantasy adventure with elements of magic and mystery. Maybe the snake ring has special powers that lead the characters on exciting quests.
