In a snowy season in the Arkala Village, there was a young boy named Lucas. Who lives happily with his family until one day... A group of criminals known as "Shadow Phoenix" invaded their village. The people got panicked as they were running away while he got knocked down and left unconscious. When he woke up, he ventured through the wilderness to seek help from others but he collapsed due to the fact that he doesn't have the energy to do so... Before he knew it, he was already inside a mansion, he was saved by a gorgeous woman and he called her his master but eventually she died because of a powerful curse that she was carrying around. The last words that Lucas heard to her was "help others even if no one would, this way you can get your revenge without regret". This is the starting point of Lucas Hart's journey.
