Vermillion: Akaki Goukyuu no Étranger

Western VRMMO DEMONDAL was known for its extremely harsh game system. To begin with, there were no levels. There were no skills. There were no guilds. There was no inventory. There were no convenient system messages or maps of any kind either. It was so needlessly realistic that it was already basically a VR life simulator. As for anything game-like, it was basically limited to weapon masteries; a proficiency level that you got from using your weapon, as well as physical strength that increased as well. That was it. It was a fantasy game so there was magic, but forming a contract with a spirit was extremely difficult, and only 1% of the playerbase were magicians.
