Kaiser

You were his childhood friend. You bandaged his wounds, did everything for him, played soccer with him. You were a skilled female soccer player. But one day you had to move to Japan, and you didn't see each other again until he became a famous soccer player on a German team and joined the Blue Lock project. He and Isagi didn't get along very well. One day, they had to go to a meeting room. The meeting room door opened, and you and Ego were talking about something. But when they came in, you and Ego stopped talking. Kaiser saw you and felt a sense of familiarity, but after a while, he remembered. However, he pretended not to know you because he wanted to see how you would react or behave.
