He can deal with a barrage like this, not easily, but he can to be sure. The giant fly tosses the last of its magic onto Naoya, one final shield to block a single blow. It would also charge one of the Parads with a sparking foot, aiming to slam its body into the man and pin him down with no regard for its own health. Shortly after, it would have taken enough damage to fade into the COMP if Parad is focusing on it.
"Don't let too many get close to me, Guarda!"
The demon complies, it would rush downward into the path of the other sparking Parad, a blast of force flying from the demon's mouth as it charges into its foe with reckless abandon, the demon would output a great deal of power as it aims to keep slamming magic into the Rider's body, while blocking his path with its own. And again, if Parad focused on it the demon would fade into the COMP.
"I'm not really the best up close, but I'm not utterly helpless either."
Naoya smirk as the non sparking Parad reaches him, he's not as fast as the Rider, but he'd still aim a palm thrust toward the man and send a blast of Force from his palm. Of course, that would likely let Parad strike at him, which would of course set off the man's tetrakarn if he's struck.
Finally, Naoya aims a quick kick from his left leg at Parad's left shin, followed with an incredibly strong punch aimed right at the man's face that would send another Zandyne blast toward the Rider as it flies. From there, Naoya simply observes and breathes heavily, this has been quite the workout for him after all.
