Ichi is a minor character of Ginga Densetsu Weed: Orion.
Ichi and his family is seen catching fish near a rapid stream when a dog howls. The family heard it and they saw Akakamakiri. When he and Jirō asked what their mother was doing, he replied to his sons that it was somebody their mother knew before he met him. They watched as she explained to her previous son why she ran away and could not take the Irish grey hound brothers with her.
Later on, the new family come across a puppy alone and scared in the forest and agree to help her find her family. As they continue up the mountain, the pup is reunited with her family as well as his mother with his older half-brothers.
