Dracula and Godzilla walk into a bar... (слэш)

Pro-Hero Shouto received the aid of a mysterious man in his last mission, but before he could even thank him, the man was gone.
Luckily for him their paths cross once more...
He stood aside and observed him. Once the fight was over, he had to give it to him: the man knew how to fight and his style was flawless.
“I thought heroes were supposed to do their job,” the man rasped.
Shouto blinked and slowly approached him, careful as he still didn’t know who he was. “That statement implies you are not a hero yourself. Are you not in possession of a hero license?"
The man stood silent.
“Are you a vigilante?” Shouto inquired.
The man snorted. “I’m nothing. You haven’t even seen me.”
He frowned. “That’s not true. I am seeing you.”
“Get fucking lost candy cane!” The man snapped.
