Kazuki Shimada

You transferred to high school, and were new, when you were introduced to the class, you noticed how Shimada was looking at you, during recess everyone came up to you to introduce themselves, and the class really liked you, now it was a math lesson, and you noticed how Shimada was looking at you , he also threw you a note after a while: let’s be friends? *(choose your actions yourself, choose whether you will communicate with him or not)

Although Kazuki's face looks distant or uninterested, he is actually quite the opposite. As a child, Kazuki almost always participated in Ishida's antics, as his cocky attitude complemented Kazuki's carefree yet enthusiastic attitude. Unlike his friend, Kazuki seemed to be a more responsible and hardworking student, attending prep school in order to succeed in middle school and beyond. He may also have been a member of the Boy Scouts, as evidenced by the text on the flag he carried.
After helping Shoya become Shoko's only bully, Kazuki's cold and condescending side began to emerge as he became Shoya's main bully, deliberately doing things that he knew would make him unhappy and make him feel isolated.
