I Was a Sword When I Reincarnated

『Well then, Fran, you ready now?』

(Nn! Sorry I kept you waiting)

The current stalemate was created by Fran, although it was Zelyse who said that it was them who was losing their interest. Well, I guess Zelyse was also deliberately playing along with us.

I think he was still observing me during our fight. That must be why he didn’t dare to attack me seriously.

(Master, let’s do it!)

『Ou!』

Normally. Getting away from here would be the best option. However, if we ran away here, Zelyse might do something to the seal of the great magic beast again.

She said that the seal was already very weak, so we wanted to stop him.

That was why Fran was so determined to win. If we couldn’t fight for a long time, then we would just have to fight for a short time.

『Haaa!』

「Thaa!」

『Resonance magic!』 (Resonance magic!)

The magic power released from me and Fran was merging into a single form.

This was our Resonance Magic, the secret technique we had acquired on the Plains of the Demon Wolf.

It was a technique in which multiple magic users resonated with each other’s magic power and activated it. And apparently, it was a very rare form of magic.

It was a unique skill after all. And in order to activate it, everyone who cooperated had to have this skill.

Even with all that, it was unlikely that the activation conditions would be met. Besides, it was not something that could be used by just having the skill alone.

The wavelength and intensity of the magic power must be kept under control to match.

In other words, they had to have resonance magic skills and advanced magic control but there were not many people who could do that in this world.

Even Amanda said she had only seen it activated a few times. She said that it was used by a group of high-ranking magic beasts that appeared deep in the dungeon.

I think the skill was originally developed for magic beasts in dungeons. Because it would be rather easy to activate it in a dungeon that could generate a large number of magic beasts of the same species and the same ability.

Me too, I just happened to have killed a magic beast that had the skill in the Plains of the Demon Wolf.

It was a mysterious group of five slimes that were connected by a tentacle-like object to each other. And their name was the Resonance Slime.

Well, we killed them before they could even use their resonance magic though.

「Kuh...!」

『Fran! Hang on!』

Fran grunted. This was also the reason why this magic could not be used in actual battles.

Normally, this magic was designed to be used by groups of ten or twenty magic beasts. The burden on the user was tremendous, as Fran and I were the only ones using it.

In particular, the stress on the brain seemed to be quite severe, and Fran got a bad headache when she tried to use this skill.

Fran even said 「It feels like someone is hitting me with a spiked hammer in my head」.

Because of this, Fran’s control was not stable at all.

「Aaaaa!」

『All right! You did a great job, Fran!』

But Fran, despite her screams, completed her part.

Fran mustered up all her mental strength and endured the pain as she completed the last part of the preparation. I then sensed my own magic power and instantly adjusted my output.

Then, a bolt of pale blue lightning shot out from us, rampaging in all directions and covering the surroundings.

「Ghaa! W-what is this...!?」

「Grrr!」

「Guh!」

Zelyse, who was still in his permeable state, was severely shaken by the resonance magic and deeply wounded by Urushi’s follow-up attack. Moreover, the lightning was still raging around us.

He must have thought it was just a Thunderbolt Magic. Zelyse was surprised that he received a direct hit by the thunderbolt while in a permeable state. It seemed that even Zelyse could not even tell what it was at first sight.

That was because of the effect of our Resonance Magic. Fran’s lightning attribute and my space-time attribute blended together, and a bolt of lightning with the space-time attribute was released.

It could be changed in many ways depending on the nature of the magic that was put into it and the image of the user. That was what resonance magic was.

However, it was not very powerful as the user’s magic power must resonate when it was used. It might fail if one of us used too much magic. In other words, it had to be matched to the person with the lowest of magic power.

And I was the one who had to adjust to Fran this time. In the first place, her headache already made it difficult for her to adjust to me.

Moreover, the magic power that was put into it was also consumed to combine the attributes, so the power was further reduced.

It was also weaker than Kanna Kamui and Heaven Judgement.

However, if the situation was one where multiple attributes were effective, as it was now, it was very useful magic. It had the speed of a thunderbolt, but also had a space-time attribute that could inflict damage onto Zelyse in his permeable state.

『Now’s our chance while the effects of the Resonance Magic are still in effect!』

「Nn!」

Fran rushed out to cut Zelyse down.

Both Fran and I are resolved to put everything we have into this blow.

But at the next moment, I, Fran, Urushi, and Zelyse all cowered and looked astonished at the same time.

「This is...?」

「Woof」

『Oi oi oi! Something is coming out of the bottom of the temple! And its magic power is really great!』

「W-why is the seal of the great magic beast broken!? I haven’t done anything...」

From the center of the temple, gray magic power slowly leaked out like it was crawling.

We then jumped back in a hurry.

「U-Uwaaah!」

Immediately after, Zelyse let out a scream. It was not a fake scream like before. It was his serious scream. But I guess that was to be expected.

「Kuh...! What’s this! Let me go―!!」

There were layers of what looked like thin strings entwined around Zelyse’s body.

If I looked harder, I could see that it was an extremely thin tentacle similar to those of a jellyfish. Countless tentacles overflowed from the gaps in the pure white floors and attacked Zelyse.

He should have been using his permeability, but apparently, it was pointless.

Seriously, is the great magic beast about to resurrect?

But why? Could it be because we fought here?

『Where’s Rhyn!? I’m sure Rhyn can tell us what’s going on』

(Nn? She’s not here?)

But then from behind me, we could hear Rhyn’s voice.

「See? I’ve told you to just run away...」
