World's Fastest Level up!

A rank dungeon – 【Meijuu Dungeon】.

As soon as we arrived, the scene of multiple adventurers fighting beast-shaped monsters entered my sight.

"Gha!"

"Ugh!"

Perhaps because adventurers don't usually fight on the surface, the encirclement that they made was imperfect, creating a gap that allowed a monster to slip through them. That monster avoided all the tanks and swordsmen and aimed at the healer behind them.

"Kyaa!"

"—!"

At this rate, that healer girl would be in danger. With that in mind, I tried to summon Greed in my left hand, but there was someone who moved faster than I could.

"Magic Barrier."

As soon as Nanami-san muttered, the movement of that beast-shaped monster stopped. This is… a barrier, huh. However, it wasn't a normal barrier, as it was created by the magic power in the atmosphere using Nanami-san's unique skill, 【Magic Power Interference】. From the activation speed to the strength, the level of that barrier was far beyond the normal barrier.

"You wouldn't think I'm done with just that, right?"

"This is…"

Suddenly, the shape of the barrier changed. The transparent barrier that swayed just like waves then spread, locking every monster in the area, excluding the adventurers. And then–

"Sky Rebellion."

–Multiple lumps of magic power ran around the barrier. The lumps gained more momentum every time they hit the barrier and reflected, annihilating the monsters inside in a blink of an eye.

At that moment, silence spread all over the area. But that, too, lasted just for a moment, as everyone in the place soon cheered.

"It's Nanami-san! Nanami-san has come!"

"The rescue from Classion has come. With this, we will be able to handle it!"

As expected of an S-rank adventurer. People instantly got their spirit back just by her appearing here. Well, since this is also the area where the headquarters of Classion is located, it's natural for people to trust them quite a lot.

However, the person in question didn't respond to their words and just displayed a grim expression on her face.

"Fumu, the worst situation has not come yet, huh. But at this rate, it seems it will take quite some time for this dungeon to completely collapse…."

Which means, from now on, we have to prevent the advancement of the monsters. But, in actuality, there is a way to avoid that.

"Will you defeat the last boss?"

"I really want to do that but unfortunately, I'm in the middle of intermission. I can't go inside."

"That means…"

"It would be best to endure the advancement of the monsters until the collapse is over and defeat the last boss that comes out after that. Needless to say, there are risks, too."

"…."

Those risks are most likely because we're fighting on the surface, not inside the dungeon. Due to that, there are many things we have to be aware of. But the most important one is damage to the surroundings. Even the monsters that come out of an E-rank dungeon can already threaten the lives of ordinary people. Thus, there isn't even a need to think how much damage the last boss of an A-rank dungeon could cause.

Still, as Nanami-san is here, I don't think it has that much risk, because as long as she uses the same barrier as before, she should be able to fight without having a need to mind her surroundings.

However,

I looked at Nanami-san and said,

"Then, I will go."

"… Are you serious? It would probably take a considerable amount of time to go to the deepest part of the dungeon now. So, I think the probability the dungeon collapse ends before you reach there is higher, though… and to begin with, I feel like it will be quite dangerous to fight the last boss with your abilities–"

"Even so, I want to go."

"—-"

Interrupting her, I declared strongly. And looking at this, Nanami-san stopped speaking.

I want to protect everyone here– I certainly have that feeling. And the best way to do that is to go along with Nanami-san's plan. Of course, I knew that from the beginning.

However, there is something that I think is more important than that right now–

Perhaps because my feelings were transmitted to her, Nanami-san's heavy expression became relaxed.

"As expected, you really just like her…"

"Eh?'

"No, please don't mind that. If you can say that much, then go. But please don't overdo it."

"Yes"

"And then before you rush inside, I will give you a brief explanation–"

Having heard some points to note regarding the dungeon from Nanami-san for one minute, I passed through the newly emerged group of monsters and rushed into Meijuu dungeon. And then–

"Transfer Within Dungeon."

I shortcut-ed the floors and headed to the boss room as fast as possible.
