And then on the other hand, in the Devil May Cry 4 Instruction Manual it states that Nero was infected (So his arm is like a demonic infection).
If they have any decency towards the people they are trying to sell the game to, they would justify their storyline. I look forward to having Nero's origins finally put to rest once and for all.
The manual doesn't say he was infected. It merely states that his arm was hit by a demon in an attack.
This is what it says:
''A number of demons appeared suddenly from deep within the Mitis Forest and attacked the city, destroying a number of houses and inflicting slight injuries to citizens. As luck would have it, Nero, a knight of the Order of the Sword, was present at the scene. All demons were exterminated. During this incident, a private female citizen who was a traveling companion of Nero's, was injured. Nero himself received a minor injury to his right shoulder.''
And yeah, me too. Even though Nero might not make any sense, I know of ways for Capcom to get him to make sense. The fact that they apparently can't mend the situation tells me they're not quite as competent in their job as we'd like them to be.
Nero was a nice character. It's a shame to just throw him away.
