Talent-Swallowing Magician

Elric Mervinger, heir to a once-great wizarding family, is unable to use magic due to a rare and debilitating condition.
While seeking a cure for his illness, he encounters the demon Mephistopheles, who attempts to possess him in order to escape a dragon’s seal.
However, the plan goes awry when Elric instead absorbs Mephisto, binding the demon to his existence.
Now sharing his body and power with the ancient entity, Elric gains a dangerous new source of strength.
As he grapples with this fusion, he must decide whether it will help restore his family’s legacy or ultimately consume him.
