Myth and Legends: World of Aldnoah

Upon appearing, the demonic beast looked at his surroundings. Today, he had confronted surprise after surprise after meeting this 8-year-old boy. It was different from his usual day when he used to sleep every day.

i don't know how he get the cat, why people say his cat is useless. How the ranking system work, what happen when he awaken. I mean at least give me more information in the beginning especially the earlier how the MC meet the cat

The world is actually very interesting...The really interesting part is how it feels real, invertive seems like a uniquely authentic character.
