"Oi Mob! I can sense the spirit, it's nearby!" Reigen, the 21st century's greatest psychic, yelled and started running towards said spirit. Shigeo Kageyama, aka Mob, nodded towards him and headed towards his mentor. The training he was doing with the Body Improvement Club allowed him to run faster and for a bit longer, which was always a good thing for anyone. Mob saw his master standing in an open space, looking around the area frequently. "Ah damn it, where is it! Don't tell me it ran away…" He was about to start walking somewhere else when Mob stopped him.

"Master, I think we're stepping on its territory." Reigen turned around and looked at him with a questioning face.

"Stepping on its territory? What do you me-" Suddenly, the ground around them shook as it crumbled underneath. The orangette was losing balance and called out to his pupil.

"Mob! We have to get out of here, it's unsafe!" The con-artist started to sprint towards solid ground, but then tripped on a medium sized rock. He was starting to fall into the pit, but then was caught by Mob's telekinesis. Reigan sighed in relief as he was being lifted in the air. "Thanks for the save Mob. However, this spirit seems to be underground, and my energy is a little low from searching for it. Do you think you can handle it?" The student nodded. He placed his master on the solid earth, and headed into the pit.

It was very dark, but thanks to Mob's energy, there was enough light to see. It seemed that the spirit burrowed it's way through the caves. The boy closed his eyes and concentrated on searching for an exact location. Unexpectedly, the area around the esper shook and right behind him was the spirit. It looked like a mole, but with three eyes, tongues and noses, and had a deep blue aura surrounding it. "Ah, there you are. Sorry about this, but I'm going to have to exorcise you for causing mischief around the neighborhood." He placed his hand in front of him, charging energy to blast the spirit away, but the ghost didn't want any of that. The mole went straight for him at a fast rate, and headbutted Mob before he could produce a barrier, which sent him flying back.

The middle schooler caught himself, cancelling his momentum. This one's quick… and when did he get so big? Mob thought as he saw the once medium sized mole turn into a giant, monstrous one, almost five times the size of Mob. It seemed like it had an ability to grow. The esper launched a quick energy attack towards the spirit, but unfortunately it nullified the attempt. Mob was puzzled. Did it have it's own barrier? He then launched a medium leveled energy blast towards the monster, but again, it got nullified and did no damage.

Mob was getting a little irritated. What was he doing wrong? His powers are supposed to get rid of these haunting spirits, and he did it many times successfully before. However, this one was giving him trouble. He was going to have to try another strategy. The boy approached the monster, but then it used it's claws to hit directly at him. Fortunately, the barrier he put around himself shielded him, but it cracked, which was not normal for a spirit to do. Not only does it have a strong barrier for itself, but it's powerful physically? Mob knew how destructive his powers could be, but didn't want to accidentally hurt anybody or the environment. He had his own limit, and it seemed the spirit was past it. He needed support for this one, and who else but from his master?

Mob swiftly turned around and flew towards the surface, but the mole made the ground shake once again, and blocked his exit with a wall of soil and dirt. He attempted to blast his way out but it once again got nullified. Did the spirit somehow transfer its energy towards the earth itself? What kind of thing are we dealing with now? The middle schooler didn't show his emotions much, but inside he was feeling one now; fear.

He was stuck in this suffocating room with a spirit mole he couldn't deal damage too. The ghost stopped waiting and headed straight for Mob, which he then put up a barrier to stop it. The mole unfortunately broke through and the boy didn't have enough time to put up another one, so he braced for impact. Instead of a blow to the head, or a rip through the heart, he was taken into the mole's mouth. He was swallowed whole. He quickly started to attack the inside of the spiritual cavern, but because of the spirit's own barrier, it didn't do anything. He attempted a couple of more times, but was getting tired and sat down on the spirit's tongue. He felt he had no hope… he couldn't get out. His powers weren't enough to defeat it. Reigen probably couldn't save him now, as he claimed to have low energy from before.

Ritsu… Mom… Dad… Reigen… All my friends… Mob started to tear up, he wasn't strong enough to beat the spirit.

It seemed there was nothing else for him to do, except give up.

Mob let his tears come out, he couldn't hold his emotions back anymore, but this time it was different. He felt a strong surge from his body, one he never experienced before. When he let his emotions out before, he either destroyed his enemy with his rage, cry his tears out with sadness, or show compassion to his friends. This new feeling though, one without hope, filled him with a newfound power he never knew before. He was going to explode, and with this starts our protagonist, Shigeo "Mob" Kageyama, a new journey he will never forget.

The air around him stilled, but then a ravage blast surrounded the area, and his explosion not only exorcised the spirit, but the entire underground facility was elevated above ground because of the force. Reigen heard it and looked at what was happening. "What the hell?!" He ran towards the noise, and saw a huge crater. "Mob!" He called out to him, but got no response. "Mob, where are you!" Nothing. He yelled with all his might. "MOB! WHERE ARE YOU?" He panted and looked at the sight in front of him. Don't tell me… No way…. The orangette has his mouth open and looked around the crater for any signs of his student, but he couldn't see anyone. He couldn't believe it. He fell to the ground and gripped the dirt underneath him. He gritted his teeth and bit his lip, shaking his head. The man yelled out one more time into the night sky.

"MOB!"
