Joeri Higashikata

Joeri Higashikata, later romanized as Yuri Higashikata, is a main character in Silver NX.

He was a student at Seven Stars University, serving as the arch-rival of Shunichi Takahashi. After the fight with Bakuro Fujiwara, Joeri became a powerful Trinity user, and following the RUIN incident, Joeri became friends with Shunichi and cooperated with him as a member of Team Monolith.

During the Zeta Race, however, he was deemed as a worthy target by Matrix and was blasted into outer space, where he was possessed by Matrix. After being defeated, Joeri regained control of his body and aided Shunichi in finding out what happened to Epsilon long ago.

Along with Serena Tenjoin, Tatsuya Honda, and Mizuki Natsuno, Joeri bore witness to his rival and Darkness' final battle.

Personality
Joeri initially carried a pious and self-righteous demeanor, as he aimed to crush any opponent with a religious fervor in his duels. He was also characterized as very sarcastic, rude, relatively selfish and power-lusting, no-nonsense and down-to-earth, and somewhat narcissistic, and petty, sometimes to the point of comedic relief. He appeared to have a certain snobbish contempt for Shunichi's group of friends, namely Judai Rhodes. While he may have seemed very realistic, Tatsuya has stated that he can be very clueless.

Despite these qualities, Joeri was opposed to inflicting fear on his opponent, calling it an excessive and despicable thing to do. He was not, however, above using the fear his opponents already have to make them doubt themselves, as seen with Judai Rhodes. As the story progresses, especially following his defeat at the hands of Shunichi and the Daisuke Morimoto incident, Joeri comes to undergo a significant change for the better, mellowing out and joining his arch-rival's group, Team Monolith, and becoming more respectful.

His personality evolved through the series becoming more an eccentric and a comic relief.

Death Chamber Arc
Shunichi thought of him, Silver, Nexus, Alpha, Omega, Judai, and Hayato when he said that he was not going to back down in his battle against Kaiser Schmidt like how they never gave up.
