Axe was once the best player in "Ryn Online," an action-packed fantasy RPG. But when his comrades kill him, Axe is forced to start all over. Devastated by their betrayal, he swore off gaming and opened a fried chicken shop to make ends meet. But when a new VR game called "Fate" is released, he notices that the friends who betrayed him are also playing. Now, he's willing to go back to gaming and munch on chicken-fried monsters to get stronger for his revenge!
