The split personality aspect is certainly the main draw of the fight, though with these two, it's portrayed more like two separate souls sharing the same body. Both sides of their personalities share a deep sense of loyalty and seem to genuinely care about one another to varying degrees. Their original selves, Sho and Doppio, can be relatively goofy in their own ways and are unable to use the full extent of their powers, yet they're still more than capable of dealing with enemy Stand/Persona users with the limitations they have.

Minazuki and Diavolo, the other sides of their personalities, are much more ruthless and pragmatic in comparison. Should they need to protect their other selves from harm, they can take control of their bodies at a moment's notice, gaining full access to the abilities of their respective Persona and Stand. Minazuki and Diavolo also share a great disdain for other people than themselves, and as such are more than willing to kill as many people as it takes to fulfill their isolation fueled goals.

The two sides of both character's personalities did eventually end up separating in the end however, whether it was because of Minazuki's personality merging with Sho or when Doppio and Diavolo's souls were forcibly split apart by Chariot Requiem.
