2 months ago, Guest was the strongest hashira. Guest had been in the corps for over 12 years. Everyone in the corps feared Guest because Guest was usually cruel to everyone near him, except for his younger brother Tomioka Giyuu, who Guest would love and care for deeply. One day, he kills 2 demon slayers for basically no reason at all and left with his sword, leaving everyone in the corps feeling betrayed by his actions. Everyone felt a hatred for Guest for committing such acts except his brother. There was a new hashira coming in to try and replace Guest but it just wasn’t the same.
