Keicho Nijimura

Keicho Nijimura (虹村 形兆) is a minor antagonist from Part IV: Diamond is Unbreakable.

Personality
Compared to Okuyasu, Keicho is the more rational and calm of the two brothers. Both admit that Keicho's ability to think far outclasses Okuyasu's, and Keicho has shown tendencies to look down on his brother for his lack of ability to think. Despite this, Keicho sacrificed himself to save his brother from Red Hot Chili Pepper's assault.

History
Around 1987, Keicho and Okuyasu's mother died, leaving their father in depression. On top of that, Japan had been going through a tough time economically and his family soon fell into poverty. Due to this, Keicho and Okuyasu were abused constantly.

However, two years later, his father began to receive letters with money and jewels. Much later in his life, Keicho would realize his father had sold his soul and heart to Dio Brando, who, at that time, was scouring the globe for a stand user capable of recreating reality.

Dio, however, distrusted Keicho's father and implanted a seed of his undead body within him. When Jotaro defeated Dio, the seed burst, causing their father to slowly mutate into a monstrous form, and later lose the ability to speak. In this form, Keicho's father would automatically heal any wounds inflicted upon him.

For many years afterward, Keicho searched for someone capable of killing his father. Keicho soon came across the bow and the stand arrow, shooting random people throughout Morioh in order to find someone to kill his father.

Diamond is Unbreakable
Keicho eventually shot Koichi Hirose, believing his Echoes was the stand he was looking for. This lead to a confrontation with Josuke in which Keicho was severely injured, and Keicho told Josuke about his family's history.

Josuke offered to restore Keicho's dad in return for Keicho's Bow and Arrow. Unwilling to do that, and with Red Hot Chili Pepper lurking behind Okuyasu, Keicho shoved Okuyasu out of the way and was electrocuted to death in his brother's place. Red Hot Chili Pepper then stole the Bow and Arrow from him.

During the final battle with Yoshikage Kira, he appeared as a ghost to Okuyasu, questioning where he wanted to go and thus, convincing him to live on.
