Amidst the great battle between the Bahaghari Kingdom and their opposing country's army, Kraftvoll and the other soldiers from the medic unit were sent to rescue the wounded on the battlefield.
As soon as Kraftvoll saw the horror of the war, he was suddenly paralyzed by what he had seen.
Although Kraftvoll was deemed to be the most talented person in the whole Nidriege continent, he was still a young man with no experience in real-life war. After all, he's been under the wings of strong people all of his life.
Fortunately, he came to his senses when the young man in his group called him. He realized that it was not worth it for him to hesitate because he might be able to save some wounded that might live after treating it.
That's why Kraftvoll began treating all of the wounded soldiers that he and the other soldiers in his group found.
