Enkidu comes from a family which practices the ancient martial arts. In his youth, Enkidu taught under the guidance of a well respected master. One day however, Enkidu's master fell sick and eventually died. Consumed by grief, Enkidu resolved to become as strong as possible and discover further knowledge through combat in honour of his late master.

During this, Enkidu sought out and fought as many others as he could. Soon, many feared him as the infamous Maneater (羅刹). Enkidu became so infamous that people actively avoided him out of fear. With no-one else left to fight, Enkidu gained a desire to fight those who went beyond even humanity, a desire that made him discover the Hollow Night and everything it entails.

From then, Enkidu immediately sought out the supposed "strongest In-Birth" in Kanzakai. In order to fight this person, Enkidu actively searched for a Void in the hopes to obtain the powers needed to fight this In-Birth. Enkidu soon found a Void and offered his arm to it. However, his battle hardened body keeps the Void from biting deep, leaving Enkidu with only a small amount of EXS at his disposal. Despite that, Enkidu kept fighting under the Night using nothing but the martial arts he has practised his whole life. Upon hearing of an In-Birth who fought without EXS, a woman by the name of Hilda sought out Enkidu and offered him to join her organization, Amnesia, under the promise that he would be able to fight as many strong opponents as he desires.
