Yama

Yama is a member of Trinity Wonder, one of the direct subordinates of the Heavenly Demon and one of his helpers in creating the Obelisk's System. As one of Trinity Wonder, Yama is one of the most powerful Gods and is universally respected and feared by many of the Gods & Demons within the 98th Floor of the Obelisk. As one of the three programmers of the Obelisk's System under the Heavenly Demon's orders, Yama possesses a deeper understanding, authority and control over the System in comparison to the Gods, Demons and Players who are the system's users. As she is known as the "First to Set Foot in the Underworld", it is likely that Yama is perhaps the first God/Goddess of Death to have emerged in the universe and as such possesses unrivaled power over the afterlife and souls compared to most other Gods and Demons of Death. As she is known as the Goddess of the Underworld, Yama also likely possesses authority and power over death.
