Seventh Reincarnation
Embark on a Journey

Next day.

"Oi, Prontea, you're alive."

Ars crouched down in front of Prontea, who was lying on the ground dying.

"Coughs... Don't joke, senior. You know we can't die."

While spewing blood, Prontea replied helplessly.

The reason for his current condition was none other than Rin's usual training.

"Don't blame Rin, he did it for all of us. Strength, endurance, regeneration, and other aspects have grown tremendously compared to you 50 years ago."

"Senior didn't have to say it, I know, I never hated Rin. It's just, I wish he could hold back."

Ars and Prontea have a good relationship, even if each Idaten cannot hate each other. Perhaps due to the innate nature of the race, they would not hold grudges against each other.

"By the way, senior will be leaving today?" Prontea asked started to stand up and patted the dust on her clothes.

"Yes, before I leave, I'd like to ask you a favor."

"Of course, senior is very good at teaching me your various abilities, I will."

Even before Ars mentioned his request, Prontea immediately agreed to it without a second thought.

"OK, it wasn't in vain that I took care of you all this time."

Ars patted Prontea on the shoulder and was satisfied with his attitude.

Compared to humans who sometimes betrayal even though they have treated it well, Idaten will never betray each other.

Although Idaten is a protector of mankind, they will not interfere if humans become extinct due to internal conflicts. Like war.

Idaten will prevent the extinction of mankind if there are foreign enemies. For example Devils, Aliens, etc.

"Follow me."

"okay."

The two of them left the island, after a while, they arrived at a desert.

Ars guided Prontea to a hole that had been camouflaged by sand, then both went into the hole and arrived at a long tunnel.

"Wow, senior made this tunnel? Since when did you make it?"

"This place I made yesterday, do you remember the location?"

"Don't underestimate me, senior. I have a good memory, I won't forget our way here."

Prontea patted his chest proudly.

"That's great." Ars nodded.

Finally they arrived at the end of the tunnel, and there was a stone altar in the middle of the room.

"Listen to Prontea, your task is simple, do not let this altar break. Otherwise, I won't be able to return to this world." Ars is serious.

"Simply put, this is the sign that senior left behind in order to get home." Prontea nodded in understanding.

"You're right."

"Then why don't seniors make another sign just in case the sign here breaks?"

"I don't want to, but I can't! The [Teleportation] magic can only mark three locations, I don't want to waste the two marks left in this world."

"So so... Senior wanted to leave his mark on another world. I don't have to stay in this place and guard the altar, do I?"

Prontea likes freedom, if not because he cannot escape Rin's radar, he would not have practiced. And now, asking him to protect the altar for some way or another, he really did not want to.

"You're thinking too much, there's no need to stay here. But every once in a while you have to check the altar and if any humans somehow make it here, drive them out."

How could Ars allow Prontea to become a Hikikomori in this place?

The main reason he chose the desert as his location to go home and go to another world, in addition to avoiding natural disasters that might occur and damage the altar, and also to prevent humans from finding it.

As a former human, Ars understood that humans love exploration.

"Just leave it to me, senior can leave quietly." Prontea.

"En, I leave it to you."

"Senior wants to go now? You're not saying goodbye to Rin?"

Prontea was surprised to see this, he thought his senior brought him here just for a demonstration.

"No need, it's not like we're separated forever. Due to time dilation that might occur, I don't know when I can return. It may be several years, decades, or even hundreds of years. If your training is over, look for a new generation of Idaten before you leave."

Ars gave a reminder to Prontea.

"All right, I promise."

Prontea does not argue, he also feels somewhat guilty if he leaves Rin alone on the island after his training is over.

"Good bye."

"Be careful on the road, senior. Don't forget to go down by the minute you return."

Prontea waved both of her hands with a wide smile on her face.

Ars smiled faintly, preferring this kind of farewell to be accompanied by crying and sadness.

This was the first time he had used [Teleportation] magic to teleport to another world. Plus, it doesn't have any particular coordinates, so it doesn't know what kind of world it will be stranded in.

(I hope to arrive in the world of modern civilization.) Thought Ars.

The magic circle under his feet shone brightly and his body turned into particles of light.

Not long after, Ars's figure disappeared and the magic circle on the altar dimmed.

"Have gone? Hope everything goes well." Prontea Mumbles.

...

Endless Void (Endless Void).

It is a space that has no end. There is no air, no oxygen, no water, and no other constituents of life, and it is filled only with cosmic radiation.

The space distorted and the figure of a black-haired youth with pitch-red eyes appeared.

That person is none other than Ars.

"..."

He tried to speak, but no sound came out of his mouth.

(Oh, right. Air cannot travel in a vacuum. So, where am I now? Did [Teleportation] fail? This place looks like space, I don't see any meteoroids.)

Meteoroids are small space rocks that float freely in space and move quickly.

Ars looked around, other than a point of light in the distance, which was likely a star, he did not find a single meteoroid.

(Let's analyze the situation more than ever, I've read several novels where the protagonist can explore other worlds and conditions are somewhat similar. If my guess is not wrong, each point of light is a world. If that's true.... Amazing, there are countless worlds.)

Ars was shocked by his own guess, he felt like a frog at the bottom of a well and the frog had come out of the well, and had only seen it the world wide for the first time.

(It's no use just guessing, let's try landing on one of the stars.)

After winning, he looked for the nearest star. After all, his speed had yet to reach the speed of light, so inevitably, he had to search for the nearest star.

(Meet!)

Finding his goal, Ars lightened his weight to 0 kilograms and flew at Mach 25, equivalent to 25 times the speed of sound.

He had surpassed the maximum speed of Koro Sensei.

Due to the absence of a metroid blocking, Ars slashed straight unhindered.

Getting closer to the star, he could clearly see the star was shrouded in a bright white light, making it impossible to see its true appearance.

Ars doesn't know how much time has passed, as there is no concept of time here, but he is thought to have flown for a month and finally arrived in front of a star of light.

(Enter or not?)

He hesitated.

Man fears the unknown, though Ars is no longer human, he still has little humanity left.

(I've come this far, why be afraid now.)

Setting his mind, he no longer hesitated and barged into the star of light in front of him.
