Ko Eun-Woo,known as Choco Bibi in Lucid Adventure, was a member of the Grass Roots Guild.
During the early years of Lucid Adventure, he was a member of Zara Guild. After Armes went missing and the Zara Guild disbanded, Choco Bibi followed The Best Swordsman and joined the Grass Roots Guild. Alongside his Grass Roots Guild Teammates, he competed in the last ever Combat Tournament. Both Choco Bibi and his team were eventually knocked out by Team Light in the Martial Arts Combat Round quarterfinals.
After the Combat Tournament concluded, Choco Bibi used the God of Time and Space's mana to mass teleport most of the players away from the Tomb of Sword in order to prevent them from being caught up in the final clash of the Gods. The mana of the God of Time and Space led to Choco Bibi's eyesight and mana lines being damaged. His mana lines eventually recovered and his eyesight was improved by a pair of glasses give to him by Tempest and Drip Soup.
After the time-skip, Choco Bibi and the Grass Roots Guild joined hands with Dark and his party in order to find Hardcore Leveling Warrior who had disappeared two years prior.
