Kimishima is Kazuma's friend main source of cash, though he is quite a bit pompous and willingly ignorant. Kimishima also happens to be rather serious in his business, as when he first meets Kazuma, he tells him to trust him because if Kazuma fails, Kimishima was to die, which is proven true. He remains a noticable and rather comical character all the way up until he dies in the anime as a result from a Hold and Holy operation to capture Kamina using the Darths. It is a running joke in the series that his modes of transportation get destroyed in one way or another, usually at the hands of Kazuma. After his death, the scene in the opening where he is briefly shown is changed to a small montage. Kimishima's death is what pushed Kazuma over the edge and caused him to flip out and strike randomly at Holy, injuring Scherrice and getting into a conflict with Ryuhou. Kazuma formed his Shell arm using Kimishima's gun and caused a door to the Alter Realm to open and caused Ryuhou and Kazuma to disappear for 8 months. He's shown to be skilled with vehicles and guns.
