Kobe is an elderly man with a mostly bald head, all of his light-grey hair is kept in the back although there is still enough to make a topknot. He wears a olive-green dotted kimono over a navy coat with a light-blue diamond patterns. As well as round, small glasses on his face. He smokes a pipe.
Kobe appears to not be particularly intelligent, as he gave fortress blueprints to a geisha to show his appreciation for her. However, he does seem to be an effective landlord, as he took those blueprints as payment when his tenant Kumagoro was unable to pay his rent.
At some point in the past, Kobe took a set of blueprints of Kaidou's fortress on Onigashima from his tenant Kumagoro due to the latter letting his rent pile up. After this, he gave the blueprints to his favorite geisha Kisegawa.
