Diamond is Unbreakable’s Keicho Nijimura is All-Star Battle R DLC
Compared to his brother Okuyasu, Keicho is more rational and calm. Both admit that Keicho’s ability to think far outclasses Okuyasu’s. He is merciless, even shooting his own brother when trying to aim for Josuke and not being apologetic, saying it was Okuyasu’s fault for being incompetent. He states that people who don’t grow don’t deserve to live, showing what appears to be a Social Darwinist view. He feels no remorse for injuring people with the Bow and Arrow or the consequences using the Bow and Arrow could have, such as with Angelo. He was also not above using a dying Koichi as a hostage to bring Josuke in. He is also a rather methodical person, doing things in a certain mannerly order such as bringing Koichi in to retrieve the Arrow and not wanting anyone to see a dying Koichi since it would draw unwanted attention. In addition, he disliked that Josuke killed a few of his soldiers since it meant they weren’t perfectly in line. He describes people who don’t know how to use Stand as being similar to riding a bike, in that if the person doesn’t know what they are doing they will maneuver badly no matter how powerful the Stand is.

Keicho tends to look down on his brother for his lack of ability to think. When he was younger, he was shown to be very protective of his younger brother while holding his abusive father in contempt. However, he still held some love for his father, but this love was misguided: Keicho wanted to euthanize him to end his heavily deformed existence. Additionally, while he was harsh and even brutal to Okuyasu (claiming he would kill him if he tried to take the Bow and Arrow), he sacrifices himself to save his brother from Red Hot Chili Pepper‘s attack, implying he truly cared for his brother all along, an act that Okuyasu and Josuke acknowledge as a sign of his care.
