Introduction
The hyper-realistic VR MMORPG 《ARCADIA ONLINE》. Guest and their comrades, now established as the saviors of the A-Rank party, encounter the mythic-grade Holy Sword 'Luminarch' while continuing their new adventure. Breaking everyone's expectations, the person chosen by the Holy Sword is Lee Dohyun, who had fallen from party leader to porter. Convinced he is the true hero, Dohyun dreams of a comeback using Luminarch's power, but as he uses the sword, his mana abnormally drains away. And finally, Guest and Kang Serin discover a strange fact. The conditions for the Holy Sword to choose a hero were completely reversed due to a bug. Is it a shining Holy Sword, or a Demonic Sword that devours its owner? A new incident for the A-Rank party begins, surrounding the worst Holy Sword born from an update bug and Dohyun's attempt to become the protagonist once again.
ARCADIA ONLINE


Arcadia Online is a hyper-realistic VR fantasy MMORPG where real-world faces and genders are reflected exactly. It features various classes such as Swordsman, Magic Swordsman, Archer, Healer, and Mage, along with a grade system where player skill and combat judgment are crucial. It is the main stage where Guest, Seo Yujin, Han Sohee, Yoon Chaerin, and Kang Serin operate, and since a recent update, abnormal phenomena have begun to occur in some items and systems.
Luminarch

Luminarch is a mythic-grade holy sword in Arcadia Online, originally designed to possess strong divine power and the strength of light, choosing only heroes with a righteous heart. However, due to a serious bug during the update process, the selection criteria were inverted from goodwill to malice and desire, leading it to choose Lee Dohyun as its master. Because it still emits a dazzling golden divine power on the surface, Dohyun believes he has been chosen as the true hero. However, in reality, Luminarch is a corrupted holy sword that continuously absorbs the owner's mana as it is used, gradually weakening Dohyun in exchange for its powerful output. Kang Serin and Guest begin to realize there is a problem with the Holy Sword's data itself while tracking the abnormal mana flow.
