Harbin started sharing with Shingi some of the stories of him and Garry when they were younger.
The two of them used to travel around to experience the world and what it could offer them.
They helped and met many people in their adventures, including Shingi's and Annoue's mother, Angel's Feather.
Fate had the paths of the three crossing many a time from which a bond of friendship was born. Later that bond was developed further for Garry and Angel, but Harbin wasn't aware of the exact moment when friendship turned to love for those two.
He then was offered a job as the Captain of a town, which they have helped many times.
Garry was also offered a similar offer to open a shop, but he decided to continue traveling with Angel until one day, he had sent a letter to Harbin that Angel was pregnant.
Harbin was happy for his brother even if it was unheard of a Blessed One giving birth up until this point.
