Kawaki's Path to Becoming a Ninja

In order for Kawaki to become a genin, it’s decided that he can take a special test that differs from the one held at the Ninja Academy.

However, he is difficult to work with, ignores the need for teamwork, and acts on his own—giving his teammates a hard time while disrupting the mission!Source: crunchyroll
