Arthur, once a successful and rich businessman, was given a second chance in another world. He was tortured for months by men his wife hired and, now... he was offered a new beginning but it wasn't what he wished for. He was met with the unexpected when he found himself to be a minuscule entity known as a Parasite. PS: MC is a hypocrite. PS2: This story contains profanity and gore so read at your risk.
Like the Cloud Sea Universe and the System Universe, the Heaven and Hell Universe has a unique strengthening system which is efficient but difficult and more complicated than the rest. In essence, the inhabitants of this universe accumulate stars of various colors and shapes. Of course, this applies to everyone but spirits and angels, which are born strong from the get-go. Angels obtain more wings through the completion of special commandments they get from Heaven. As for other races, they rely on Star Accumulation, which is, in more than a way, a good way to become stronger.
