Rohan Kishibe/Personality and Relationships

Personality
Rohan is very much aware of his nearly superhuman skill and his success in his profession as a mangaka, thus his attitude towards others is seen as arrogant. He doesn't socialize much as he finds most people to be "incompatible with his wavelength" (especially Josuke, whom he greatly dislikes). Even Koichi Hirose, the one person Rohan does consider his friend, frequently calls him overbearing and pushy, especially when Rohan successfully manipulates Koichi into assisting him in his work research several times. Rohan is also an expert at psychological mind tricks. He tends to cover up his true feelings with his arrogance, although he is not without his sincere moments, as seen when bidding farewell to the ghost of Reimi Sugimoto.

Being very successful at his job results in massive wealth - evident by his house worth several million yen or the Gucci watch he wears. He does, however, make it a point that he never was interested in gaining fame and wealth. His only passion is to create manga, and he goes to great lengths for his research to make his work feel as "realistic" as possible. He is eccentric in procedure and manner, and could even be said to be slightly childish. Even though he acts indifferent to the affairs of others, he does believe in the forces of good, making him a valuable ally in the chase against Yoshikage Kira – especially after hearing the tragic story of Reimi, of which he is directly involved.

Friends

 * Koichi Hirose: Koichi was one of the first people Rohan met upon his return to Morioh. Despite trapping Koichi and using him for new manga ideas, Rohan shows more trust and friendship towards Koichi than the rest of Morioh's inhabitants. While Koichi is often perturbed by Rohan's near-obsessive behavior over him, he also has attempted to help Rohan in return.
 * Reimi Sugimoto: As a ghost, Reimi still treats Rohan as though he were a child. While he often acts begrudging towards her treatment of him, he also shows unceasing determination to find her killer, as Reimi had sacrificed herself to save Rohan's life as a child.
 * Josuke Higashikata: Josuke and Rohan loathe each other, with their relationship being strained at best. Rohan views Josuke as simple-minded, and Josuke is often annoyed by Rohan's arrogance. Despite their sharply contrasting personalities, Rohan shows some trust in Josuke despite their rough history together.
