Josuke Higashikata (JoJolion)/Personality and Relationships

Personality
The protagonist is an amnesiac and as such does not remember his life and personal traits before meeting Yasuho, and sometimes becomes nostalgic about this. He is very serious and a detailed observer, capable of accurately describing the physical characteristics of any object, including its color, length, and measures. He also has a certain nobility as avoiding acting cruelly to people weaker than him. He has a great respect for the feelings of others, forgiving his enemies and understanding their motives, even if it causes him difficulty.

The protagonist also has a childish ignorance of common things, likely a result of his advanced amnesia. For instance, he favors sleeping underneath a whole mattress rather than bedsheets for its "increased compression". Yasuho is able to use his naivety for comic relief.

Relationships
Extensive retrograde amnesia prevents Josuke of any notion of an original self, history or family. His first contact is with Yasuho Hirose, his discoverer; and he survives in the Higashikata family household after tentative adoption by Norisuke Higashikata IV.

Friends
Josuke holds Yasuho in uniquely special regard, as the first person he has ever met or known. Yasuho's casually considerate nature with Josuke in the first instance is to have naturally built with his trust. They are the only remotely certain allies in the story so far, and they seem to hold for the other the particular seeds of a romance.

Family
Mutually suspicious; Josuke's natural curiosity as to his origins and Norisuke's intentions carries him beyond the boundaries set for him by the Higashikata patriarch as condition to his residence at his family home. Daiya consistently expresses an amorous fondness for Josuke, which Josuke sagely deflects and pays with kindness. An arms-length reception of Joushuu persists, out of regard for Joushuu's acute emotional instability, immaturity and jealousy.
