Professor K is the final boss of the Professor K Nest.
No one knows what his original name, we just call him Professor K or Dr. K.
He had been showing off his talent in the field biology, but since his wife died from the disease of unknown origin, his whole being has changed.
He saw that any magic cannot save the life of his wife, and since then he could no longer believe anyone.
It is said that from that time, he began to keen to study of immortal life.
Later in the desert somewhere, he created a life very close to his goal.
