“The only way to reward what happened, is to save more lives than died for you” the old man was sitting like an Indian on the tatami, without looking at his disciple.

Kuwajima never gave up, but gave a chance to those who wanted to do good, developing a paternal feeling for all his students. He was happy to see them improve, even though after they left the nest, they never sent him a single letter to see how he was doing.

It's a reality.
