History
Lay Glanzudlii was born into a renowned family of magic users, the Yesta family, but he wasn't able to inherit their magic and cast out. This occurred because inheriting magic is a type of source magic, and there was already a stronger source magic influencing Lay's source; Reincarnation .

When Lay was 5-years old and all his family expected for him to die, a half-demon-half-spirit woman named Sheila took him to her home and started taking care of him, becoming his adoptive mother. This incurred the rage of the Yesla family, so the two moved far away where they couldn't reach them.

After Sheila enrolled him in the biggest sword dojo of their city, he quit 3 days after because he beat his master.After that, he started participating in different competitions, but he hardly lost. Due to this, he received the name of "The Demon Sword Saint" and was recommended to the Demon King Academy.

While visiting her one day, Lay told her about Anos, the first person who was able to make him feel defeated.
