Reincarnated as an overpowered unknown

ADVENTURE BEGINS

At this moment in a certain forest, lightning began flashing in the sky, followed by which a really big lightning came crashing down the sky peircing through the ground, it continued for a few moments before finally it stopped after hitting solid ground.

At this moment from where the lightning struck, a silhouette of a person can be seen standing up.

"Hngggh! ughh where am I?", at this time I woke up, I got up and looked around, I noticed that I was in a dark place, I looked up and saw water dripping down to the floor.

"A cave huh? But why a cave? Shouldn't I be reincarnated into a family? Or at least in a city?" I thought out load, But at this moment, a voice resounded in my head, "hey Toshiro, can you hear me?".

when I heard this voice, I was surprised and couldn't help but exclaim while looking around,"Airi?! Where are you?".

After a few moments light began shining in front of me, after which a beautiful girl appeared in front of me, it was actually Airi.

When I saw this, I finally understood what happened,"Oh, I see, so you were in your consciousness form, that was actually quite cool".

When airi heard this, she nodded her head and said,"How about we roam around this place for now? the earlier we find the exit to this place, the better".

When I heard this,  I nodded my head and chose a random direction and began walking.

...

At this moment in a certain cave, there were two people walking side by side.

"Hey airi... How do you check my stats? I'm quite curious as to what my stats are".

"Hm? I don't really have to, when you arrived here you probably had the information in that head of yours right?".

"Hm? I don't think so".

"Hm... That's weird, I remember God saying that once you arrive the info of yourself will already be imprinted in your mind".

"Hmm that really is weird I guess... Well lets think about it later, for now lets just find the exit" upon saying this, we continued walking randomly in search for the exit.

After walking for some time, we arrived at an open space somewhere in the cave.

"Hm? What are those?" upon arriving, I saw crystal like things shining around me, they had a rainbow color and were quite big. I walked towards the closest crystal near me and stood right beside me. Airi was standing behind me  observing.

I reached out my hand to touch the crystal and when my hand touched it, it was suddenly sucked into my body I began to panic when I saw this, but after a few moments a voice resounded in my head.

"Airi did you hear that?!" I exclaimed to airi.

"Hm? Hear what? Did you hear something?".

Surprisingly airi did not hear the voice, I pondered on it for a moment before moving towards another crystal, I reached out and touched it and once again it was sucked into my body, after which the voice resounded once again,"PRISM CRYSTAL ACQUIRED".

"There it is again did you hear it?" I looked at airi and asked once again.

But surprisingly her answer did not change and was still the same. I began thinking that it was weird so I tried touching other crystals, every time I touch one, the voice would resound in my head.
