His personal history is not explored in great detail throughout the series, but there are hints that he may have been involved in questionable or shady dealings in the past. Regardless of whatever came before, he has settled into a routine as a regular patron of Shocker-san's establishment, where he enjoys spending time eating and drinking in the company of the other regulars. Within the story, Kojima frequently takes on an advisory role, offering guidance, practical advice, and a listening ear to the other characters when they face problems or moments of uncertainty.

This bond is a defining aspect of his place in the series, and his loyalty to Shocker-san and the group is a consistent trait. Over the course of the narrative, his faithfulness is tested on multiple occasions, but he never wavers in his support, proving himself to be a reliable and trustworthy ally. He does not possess flashy or supernatural abilities; instead, his notable strengths are his steadfastness, his life experience, and his willingness to stand by his companions when they need him most.
