Hairo Rich

Hairo Rich is a former soldier of the Bennett Church Army and a current member of Fushi's Immortal Army.

Personality
It is described by Fushi that Hairo is more stable than others, that he can shutout the pain felt by normal people. But this is also his weakness, since he can't feel pain, he wouldn't notice his wounds, neither how other people are hurting emotionally.

Background
Hairo grew up with a foster mother named Tasset. She was very caring, yet also cautious. His routine consisted of learning about the Bennett church. He aspired to become a swordsman after learning about them in a book.

He was brought to the Bennett church because he was thought to have a demon possessing him.

The earliest memory Hairo recalls is of all of his teeth being pulled out, and whenever he grew a new one, they would pull it out as well. As a result all his meals were runny soup or porridge. Though for his birthday, Tasset gifted him prosthetic teeth. He described his life from that moment on as "My world went from zero to one."

The next day after his birthday, his foster mother was replaced for 'having commited a sin and being punished accordingly.'

One day, he became the head soldier of the Bennett church and Hairo decided that if there was a chance to flee, he would. And so, Bon found him.
