Ash is a male character from the anime Saint October. He is an adult with blonde hair cut to chin length and black eyes, and his appearance typically includes a suit and robes. Standing 182 centimeters tall and with B blood type, Ash is 37 years old.

Within the story, Ash holds the position of secretary to the president of the Reverse Corporation. However, his role extends far beyond a typical secretary; he is authorized to act as a proxy for all instructions when the president, Kurz, is absent. He possesses the power of Card Number Five, which represents The Hierophant.

Ash has an expression that is often compared to a Noh mask, making it nearly impossible to discern what he is thinking at any given moment. Despite this inscrutable demeanor, he displays absolute loyalty and obedience to Kurz. His way of thinking aligns perfectly with that of his superior, as he is described as cold-blooded and ruthless. He operates without allowing any personal feelings to interfere with his duties, and he does not hesitate to mercilessly cut off any employee who proves incapable, regardless of their position within the company.

In terms of key relationships, Ash personally scouted the Imperial Hunter who serves as his direct subordinate. There is also a past connection between Ash and the character Joshua, though the exact nature of their history involves some form of conflict or unresolved issue.
