Those who enter the Death Space fall into two categories. One comprises those forced into it by circumstances beyond their control, such as being pursued by enemies, or only being able to gain strength and fulfill their dreams by entering the Death Space. The other includes those who choose to enter the Death Space actively, seeking a breakthrough or for their specific goals.
