Yoriichi Becomes A Demon Slayer

When Yoriichi was young he couldn’t bear the feeling of hurting someone. This is why he chose not to become a samurai. However, when his wife and unborn child are killed by a demon he claims back his sword and decides to become a demon slayer. His abilities and prowess were enhanced because of the demon slayer mark. Later, he developed an original breathing style known as the sun breathing style.

Trying to help other demon slayers Yoriichi modified his sun breathing style into different styles to suits their techniques. The variations created were water, wind, flame, stone, and thunder breathing techniques.

Yoriichi’s Final Battle

After living for 80 years, Yoriichi eventually becomes blind and encounters his brother who has turned into a demon named Kokushibo. Also, Yoriichi is the last sun breather standing as Muzan kills all the other sun breathers so that no one can teach the breathing style. This was Yoriichi’s last battle as was surpassed by his age and he dies without killing his brother. When Kokushibo strikes at his brother’s corpse angrily he sees that Yoriichi still carried the flute he gifted him till his last breath.

How Did Yoriichi Live So Long With The Mark?

Unlike the present demon slayers, Yoriichi was born with a flame pattern demon slayer mark. In the Sengoku period, it was considered a bad omen, and Yorrichi’s father decides to send him to a temple when he turns 10. It is a fact that a demon slayer mark can only be unlocked when a demon slayer survives an increased heart rate of 200 bpm and temperature of 39 degrees celsius.

It is surprising that even though being born with the demon slayer mark, Yoriichi lived till the age of 80. Usually, a demon slayer who awakens the mark is destined to die at the age of 25. There are only two demon slayers who have avoided death at an early age. One being Yoriichi and the other being Kokushibo. As for Kokushibo, he avoided dying by turning into a demon and becoming immortal. As Yoriichi was born with the demon slayer mark, it can be assumed that his body was used to the fast heartbeat and extreme temperature. This might be the answer to how did Yoriichi live so long with the mark.
