For this question, I would like to nominate Ciel Phantomhive, the protagonist of Black Butler. This character can be said to make me feel very uncomfortable and distressed. I am his mother's fan.
Actually, I was very young when I watched the anime "Black Butler", and I didn't understand much of the plot. In addition, the anime did not fully restore the plot of the manga, and some parts were not well expressed. It's very obscure, so even though I've watched the anime, I just think Ciel is cute and delicate, but also cold and cruel.
When I went to review the anime when I was older, I found a lot of things I didn’t understand, so I read the comics and searched for additional explanations of the anime plots by people who had read the comics. I finally understood the anime and understood Ciel's misery and abuse.
The Charles family was originally the queen's loyal dogs and loyal to the queen, but because they had too much power and the queen's secrets, they were secretly persecuted by the queen. After Ciel's parents died in front of Ciel's eyes, Ciel and his twin brother were captured by the nobles in the underground auction market. Those disgusting nobles used Ciel and his brother to perform evil sacrifices. Ciel and his brother After suffering humiliation and torture, Ciel's brother finally died in front of Ciel in a very tragic manner.
When Ciel realized that he was about to die, he summoned the demon butler "Sebastian" with extremely strong hatred to "help me kill all my enemies." Just give your soul to the devil" and make a contract with the devil. At this time, Charles has become a person with no desire to survive, and the only belief that supports his survival is revenge.
Ciel is still a child, and he is no longer a "child". He is used to seeing the filthy desires and the darkest hearts in this world. He has no one he can completely trust and has lost the joy of life. He just wants to find all his enemies as soon as possible, take revenge and have his soul eaten by the devil forever. to leave this filthy world.
