Isekaid 40ish Man Returns, Regressed as a Peerless 17-Year-Old

The lesser oni snarled at me as we approached the man in white coat and the politicians while invisible.

The lesser demon detects us.

I, myself, am suppressing my magic power but Futaba can’t do that. That must be the reason why it can detect us.

「Is someone there!?」

—jiriririririri!

The man in white coat pressed a button on his hand and blue rain fell from the ceiling at the same time as the sound of the emergency bell.

「Uwaa! What the heck is this water!」

The politicians covered their heads with their hands.

What came down was not acid but just colored water.

In the dense rain, only the place where me and Futaba were standing, wasn’t rained at.

At that time, the invisibility magic broke.

-0-

Does it have an anti-invisibility capability?

Well, this kind of magic is usually automatically broken when the other party is aware of your presence.

That’s what happened.

Assuming that they prepared that colored rain for this kind of magic, that means they have knowledge of variants other than lesser onis.

However, even if they find out that I’m here, that won’t change anything.

I drove my fist to the temple of the two politicians and then chopped the medulla oblongata of the man in white coat, knocking all three of them.

On the other hand, the lesser oni is trying to charge at us repeatedly but it is being blocked by the tempered glass.

「I have nothing against you but……」

My finger pointed at the lesser oni and emitted a flash of light. After that, a hole as big as a fingertip appeared in the tempered glass and the lesser oni’s forehead.

A moment later, the body of the lesser oni was shattered by the magic power I sent.

「Uwa……you’re soaking wet……」

I magically created warm air and turned it into a weak tornado that swirls around me and Futaba.

Our clothes dried fast but I can’t do anything about the blue stain.

I don’t plan on doing some detergent commercial.

「Not only high-power magic but also this kind of fine-tuned magic……I’m kind of not surprised whatever you do anymore……」

I took my hand away from Futaba, whose eyes were glued to the screen because there are too many things happening at once. I tried operating the nearby terminal.

This CTR display is nostalgic.

It seemed to have been operated until just a few minutes ago and it doesn’t need a password.

「Oniichan, it’s not safe to stay in one place too long.」

Futaba was right but there were not many chances to access the researcher’s terminal.

I restrained Futaba with my hand and continued to operate the terminal.

-0-

Impossible…..

They even do this…..

As expected, access to important files was locked but I was able to obtain some important information.

In the midst of all of this, there’s one thing that we really need to verify.

The floor plan of this building is……found it.

Access is limited but I found the target location.

-0-

I picked up Futaba and ran down the hallway.

On the way, reinforced glass opened and some lesser onis came out but I just kicked them off instantly.

-0-

It’s right under here.

I made a hole on the floor like earlier and slowly descended.

Then, a living severed head in a cylindrical case filled with clear liquid appeared in front of us.

「What’s this? I didn’t expect to see you again so soon.」

The living severed head said that with a meek smile while bubbles came out of his mouth.
