Hell of a burn (my hero academia/blue exorcist)

Bright

Third person pov
"Blue flames?" Rin said as he stared at his hand

[ice crackling]

"H-holy crap!" The goons screamed as they ran away

"R-rin" todoroki said as he realized the flames didn't come from an attack but from rin as his eyes widened "you have powers?"

"No! I don't! Damnit" rin snarled 'What the hells going on?!' Rin thought

"Ah those blue flames are indeed proof that you are the son of satan" the boy from before walked back up to rin "I was right...my eye was unerring"

"Rin?" Todoroki asked

"My name is astaroth. Come with me my young prince. Lord satan has long awaited you." He said and held out his hand to rin

"S-satan?" Rin flinched

"Tch" todoroki snarled and waved his right hand as ice knocked the guy away from rin again

"You. You're no demon. What the hell are you" the boy snarled when Rin and todoroki flinched

'Demons?' They thought

"Evils are In their hearts..." They heard someone say and looked up to see shiro "o lord...give them according to their works, and according to the wickedness of their inventions, according to the works of their hands give thou to them: render to them their reward. Thou shalt not destroy them, and shalt not build them up..." he said

"Curses...are you an exorcist?" Astaroth yelled as he looked to Shiro

"Blessed be the lord" Shiro smirked

"Old man?" Rin looks to shiro

"I'll rip that mouth of yours apart, so you can never utter suck spells!" The demon snarled and charged for shiro when todoroki surrounded him in ice

[ice breaking]

"Agh!" The demon broke through as he charged for Shiro again

"For he hath heard the voice of my supplication" shiro said as he doged the demons attacks "the lord as my helper..." he said and threw the demon on his back "and my protector. Though shalt perish where thou stand!" Shiro said as the demon began to leave out of the boy

"Agh!" The demon yelled out

"Are you alright?" Shiro asked the two boys

"never mind is that guy gonna be all right?" Rin asked as his flames disappeared completely

"I exorcised the demon who had possessed him. I'm sure he'll come to in a moment" shiro said

"So that guy was really a demon?" Rin asked

"You can see them now too can't you?" Shiro said and blew away one of the bugs todoroki and rin saw

"That's one too?" Todoroki said and lit them on fire as shiro flinched

"where are you from really" Shiro asked
