Meanwhile outside of the library, Gray and Lyon were walking back to their dorm rooms together.
"Gray I have the best news ever." Lyon told him.
"Really? What is it?"
"I just met this amazing girl. She's smart and pretty and very talented."
"She does sound amazing. Is she interested in you?"
"Well she didn't want to go out with me at first. In fact she told me that at the moment she had feelings for another guy but I was able to talk her into going out with me tomorrow night."
"That's great. You think she has a friend she could hook me up with?"
"Well she does have a really cute room mate. I'll ask her to introduce you to her during our date tomorrow."
"Thanks."
They were halfway back to their room when suddenly Lyon stopped.
"Hey what's wrong?" Gray asked.
"I just remembered that I forgot something. I better go back and get it."
"Do you want me to come with you?"
"No you just go on ahead. I'll see you later."
"Alright."
Lyon rushed off after that and it was in a very quick way that made Gray feel a little suspicious but he brushed it aside as just meaningless paranoia. He went on to his room, pulled out a text book on blood work, and started to study it. An hour later he heard a loud booming sound come from outside. Looking out the window he saw that an explosion had taken place at one of campus classrooms. Sensing danger, he quickly changed into his costume and went to investigate. Natsu had also seen the explosion and he quickly jumped from his seat, running to the door.
"Natsu where are you going?" Lucy asked.
"I'm going to see anyone was hurt in that explosion. You stay here where it's safe." He told.
"Natsu wait! Come back!" She called.
But he didn't. Instead he ran into a corner somewhere and changed into his costume. He and Gray met up at the same time and just as they suspected, Black Demon was the one behind this. He had blown up the classroom where Professor Lancer had been grading his papers. The two heroes fond him under his desk in critical condition.
"Is he still alive?" Natsu asked.
Gray checked for a pulse.
"Yeah but we need to get him to a doctor now." Gray said.
"Don't waste your time! He'll be dead in just a few minutes!" Came the sinister chuckle of Black Demon.
"What the hell is wrong with you?!" Gray asked. "Why are you attacking these people?!"
"That's none of your business cat boy and to be honest I'm looking to talk to you." He turned his attention toward Natsu. "So tell me Red Dragon, did you think about my offer? What's your answer? Are you in or are you out?"
"It's you who's out man. Out of your mind!" Natsu shouted.
"Wrong answer! But if that's the way you want it so be it! But just know this! If you're going to be my enemy then you better prepare yourself for the most horrible torture imaginable!"
He then threw another bomb. Red Dragon and Blue Tiger quickly grabbed Professor Lancer and jumped out of the way of the oncoming bomb. There was another explosion but luckily no one was harmed. After leaving the professor at safe spot that was in clear view of the upcoming police cars and ambulance, they chased after Black Demon who jetted away on his glider.
"You'll never catch me!" He taunted.
"We'll see about that!" Natsu said.
They chased him from the campus and through the streets of the city. Disrupting traffic and causing bystanders to duck in fear. They were getting awfully close to him so the villain decided to slow them down by throwing a bomb on to a nearby road bridge. There was another explosion which caused various cars to flip over and one car to get knocked off the bridge. Acting fast, Natsu shot down a grabbling hook that Erza had given him and used it to catch the falling car. He caught it in time but it was dangling.
"Help!" Cried a man who looked over the bridge at the dangling car. "Someone please help! My son is in there!"
"Gray you help those people out of their cars, I'll get the boy." Natsu said.
"Right."
Gray jumped down and quickly began helping passengers escape from their flipped over vehicles while Natsu climbed down the line of the grabbling hook and toward the car. A little boy was indeed inside and he looked scared out of his mind. Of course who could blame him? Natsu broke one of the car windows and reached out to the boy.
"Kid are you okay?" Natsu asked.
"Get away!" The boy screamed in fear. "Leave me alone!"
"Hey it's okay I'm not going to hurt you."
"I want my Daddy."
"I can take you to him. I'm gonna get you out of here and I'm going to take you back to your daddy but I need you to do exactly as I say, understand?"
He nodded.
"Okay right now I need you to try to climb toward where my arm is reaching out to you. Can you do that?"
"I can't! I'm scared!" He whimpered.
"I know. I'm scared too."
"You are?" he said in disbelief.
"Yes I am very scared right now. There's nothing wrong with being scared but you can't let it stop you! If you just sit in here you'll die and you'll never see your dad again! Is that what you want?"
He shook his head.
"Then you have to climb out of the car and over to me. You'll be alright I promise!"
Natsu reached his arm out to the boy again. The frightened child hesitated at first but eventually he unbuckled himself from his seat, climbed toward that broken window, and grabbed on to Natsu who pulled him through the window and climbed back up the line while carrying him.
"Are you alright?" Natsu asked him.
He nodded.
"Good. Now let's get you back to your dad okay?"
When he finally made it back up to the bridge he handed the boy back to his father who was greatly relieved to see that his child was alive and unharmed.
"Thank you!" The man said to Natsu in a grateful manner as he held on to his son. "Thank you so much!"
"You're welcome sir."
Natsu then went to help Gray rescue the remaining passengers. By the time they had gotten everyone out and to safety, Black Demon had disappeared. They spent the rest of the night trying to find him but it was no use. There was no trace of him anywhere. By morning they were both exhausted but they were grateful that it was a Saturday so they could sleep in that day. After sleeping from eight to one, Natsu went over to Gray's dorm where they discussed what they were going to do about Black Demon.
"I think our best bet right now would be to figure out who this freak is." Gray said.
"One problem with that. We don't have any potential suspects." Natsu said.
"Maybe we're not just looking hard enough."
Knock-knock!
"Coming."
Gray got up and answered the door. Standing on the other side was Juvia.
"Oh hi Juvia." He said.
"Gray? What are you doing here?" She asked, surprised to see him.
"What do you mean? I live here. This is my dorm."
"Oh...Oh dear then that means your Lyon's room mate."
"Yeah I am. Hey how do you know Lyon?"
"Well the thing is I...I have a date with him this evening."
"What?!"
"Oh snap!" Natsu said.
