He usually doesn't tell anyone because he doesn't think people will believe him, and he doesn't want the attention. In reality, Tsuzuki is really powerful. So powerful that a demon lord wants him to work for him, but Tsuzuki doesn't want to hurt more people. As far as popularity goes, he's gone over seventy years in the Ministry and never gotten a raise due to check cuts for damage repair. We sure do know how to blow stuff up! Hehe!
