On top of that, the monsters could only have access to spells he could cast himself. Worse, the spells had to be pretty weak, relatively speaking, because of how limited their magical power was.

It forced him to work on designing ultra-efficient spells, which was honestly a great thing for him personally. Another nice thing was that the monsters didn't have to use magic circles.

He wasn't sure how that worked, but once he assigned a spell he knew to the monster, they could just cast it using their own magical power. He was a tad jealous of that as the magical circles always appearing were kind of annoying.

He was really enjoying their reaction to seeing the first monster with access to magic, so he was rather surprised when he saw a thick cloud of black smoke infiltrate the scenario in the middle of the battle between the devils and the goblins.

He was further surprised when a young man appeared out of that black smoke only to take an icicle to the temple and fall over dead.

"Seriously? What the fuck?! What's with people dying to weak shit in my scenarios?! AND WHO THE HELL ARE YOU?!"

Ryuji was rather disturbed that someone had broken into his scenario only to die an instant later to a weak ass spell. The icicle spell he'd designed for the goblin was more like an icicle bullet.

It was just a sharp piece of ice about three inches long and one inch wide at the base. He knew that Rias and the others could easily handle such a spell. It was designed to keep them on their toes and maybe give them a bruise or small wound, not fucking kill some random nobody!

He opened his inventory and looked at the new body sitting in a slot not too far from Issei's body, "Who the hell are you?"

Rias watched in horror as the stranger that had somehow appeared from black smoke took the goblin shaman's icicle to his right temple. The small shard of sharp ice moving at high speed easily pierced into the man's skull and killed him instantly.

It all happened so fast that she had barely even had a chance to sense that the man was a magician before he was unceremoniously killed.

Now wasn't the time to wonder who he was or how the hell he had gotten into the middle of their battle. There would be time for that later. For now, they needed to finish off the goblins and that goblin shaman was a serious threat.

The only member of her peerage who likely could have taken that icicle spell and shaken it off would have been Koneko. It needed to die, now. She called on her Power of Destruction forming a magic circle from the palm of her right hand and aiming it at her target.

At the same time she called out, "Akeno, focus fire on the caster! We can't let it get another spell off."

Akeno acknowledged the order by firing off another lightning spell at the goblin shaman. Yet again, another of the weaker goblins took the hit for the shaman. She didn't let up though and continued to fire off blasts aimed at the shaman.

While she whittled down the suicidal goblins protecting the shaman, Rias had gathered her power. With a shout of effort, Rias fired a large blast of her power that erased everything in its path, including the shaman.

The moment the shaman died, the fat goblin let out a roar of rage. Its skin turned red while steam poured off of its body. As they watched, shocked, it's fat quickly vanished and turned into bulging muscle.

Its transformation complete, the goblin kicked off of the ground and charged head first at Koneko as she was the closest to him.

Koneko was in mid-recovery from punching a goblin through the air when the previously fat, now muscular, goblin's fist slammed into her face from the side.

The powerful blow sent Koneko through the air to land on the ground and tumble to a stop. She recovered near instantly, hopping to her feet and facing the new threat. The only sign of the goblin leader's blow was a slight scuff on her cheek.

Not wanting to let the goblin leader have the initiative, she gave a quiet, "Hup" and dashed directly at it with her fist cocked back.

The goblin didn't stand down and cocked its own fist back. As she closed and threw her punch, the goblin reciprocated and their fists clashed.

The clash of their fists echoed like two pieces of iron slamming together. However, it was the goblin that screamed in pain as its fist and wrist crumpled under Koneko's relatively smaller one. Koneko didn't let up.

Before the goblin could recover, her left fist came crashing into the goblin's stomach with enough force to bend it over her arm and cause it to gag.

With the goblin bent over her left arm, she cocked her right back and threw a punch directly into its face.

The powerful blow distorted the goblin's face breaking its cheekbone and sending it crashing to the ground where it proceeded to roll away until it slammed violently into a tree. The goblin leader didn't even have a chance to recover before a wave of red and black power washed over and consumed it.

From there it wasn't much effort for them to finish off the remaining goblins. Though Rias and Akeno did have to break out some water magic to put out the fires before they spread. Dungeon or not, the trees burned just like real ones and produced real smoke.

With the fires out and the smoke cleared, Rias took the time to check on the man who had broken into the dungeon and died nearly instantly.

She had a sneaking suspicion of which Sacred Gear the man had been using, but she would need to confer with Sona, and possibly some others, to make certain of it. A quick scan with her magic showed the man was definitely very dead. She tried summoning her Evil Pieces to her but, as she had expected, the summoning failed. She wasn't certain she could revive him anyway.

The damage to his head was pretty extreme and Devil healing wasn't the fastest or most effective kind.
