Masashi Kishimoto said this quote
“ When a person dies, he disappears, along with his past, current lifestyle, and his future. Many people die in missions and wars. They die easily and in surprisingly simple ways. Hayate was one of them. Those who died had hopes and dreams, but everyone has something as important as those: parents, siblings, friends, lovers; people who are important to you, they trust and help each other. The bond between the people important to you ever since birth and the string that binds them becomes thicker and stronger as time goes by... It's beyond reason. Those bound to you by that string will do that because it is important. ”
