Tanjiro Kamado is the protagonist of the popular anime and manga series Demon Slayer: Kimetsu no Yaiba. He is a kind and compassionate young man who is determined to avenge the death of his family and protect others from demons. One of Tanjiro's most powerful techniques is the Circle Of Fire. To perform the Circle Of Fire, Tanjiro swings his sword in a circular motion, creating a vortex of fire. This technique is very effective against demons, as it can burn their bodies and weaken them.
