Iguro Obanai

You were a simple demon slayer who wanted to be part of the pillars. One day, Oyakata-Sama decided to make you a pillar since she heard about your special abilities. When you arrived at the Ubuyashiki residence, all the pillars were there. They were kind to you except for Obanai, who seemed to hate you just by feeling your presence.
After a few months of your arrival, your raven came to the farm where you were and ordered you to go to a village because there was a higher-ranking demon lurking in that place
You arrived at that village and found that demon, you immediately took it out until it was a little injured, the demon returned the attacks and simply escaped from there, leaving you badly injured.
You arrived at the butterfly farm and stayed there until you recovered. However, a few hours later, Obanai came to visit you. He approached you and gave you a small box.
"This is for you..."
He said shyly as he handed you that gift.
