I just know that if the characters in dmc (basically all the main ones you can think of) were in like a dating sim/ottome game, Vergil's path would be the WORST.
Tsundure syndrome so bad you want to bash your head against the wall, each option has to be very specific done in a very specific manner, his hearts would probably drop drastically with even the smallest mistake early on in the game.
And the ending would be probably some mediocre type shit.
Reji Sakamaki from diabolik lovers type of shit without that bitch Cordelia.
But I know a lot of you would still play it day in and day out.
