I became a skeleton but I have a questionable skill

The world has fallen once again, it became a hell hole for everyone. The sky that was once blue and beautiful became an endless fog of smoke. The grass and the field that everyone loved became dirt and full of trenches. Yes… This is war. This is world war 3. My name is Rentaro Satou, I’m just a 29 years old soldier and in 5 minutes I will become the legendary 30-year-old virgin wizard “*sigh* I want to lose my virginity but instead I'm stuck in a trench with buffy men. I wanna go to a brothe-” "BOOOMMM!!! BOO-BO-BOOOMM!!"                           Without them knowing their trench was bombarded by an artillery plane.   “Am I already dead? Am I in heaven? Is this the afterlife” I thought to myself. I tried opening my eyes but the only thing I saw was darkness. An endless abyss of darkness, swallowing all my thoughts. Until a droplet of water came into contact with my face, followed by many drops through my body. I can feel it. This constant drop of water, it's raining. Suddenly I felt a warm and gentle hand, slowly touching my face. Then I heard a soft and feminine voice in my thoughts “rise” All of my senses came back from me, I heard the rain pouring down, thunder roaring through the heavens, lightning slashing through the skies. As I opened my eyes, I looked at the stormy night sky, then a silhouette of a girl blocked my view. I looked at her pearl white skin, her beautiful black hair, and her blue crystalized eyes. The jet black cloak that she was wearing, it feels like she’s an angel of death. At that moment, I felt something familiar within me, as if I am alive. I tried moving and I slowly stood up from the hole I was in. I looked around and we were surrounded by the forest. I didn’t know where I was but what I know is that this is not Japan. I tried to walk and I saw my reflection in a small puddle created by the rain. Finally, I noticed my own appearance. I was shocked to see my body. My flesh was gone. My skin vanished. All I could see is a skeleton covered in dirt. I look back at the hole where I was laying down and realize that it was a grave. I saw a fancy tomb and a coffin filled with treasure and gold. I couldn't believe what I saw. “Is this me? Am I a skeleton?” I wonder She replied with a soft and gentle voice “yes. Yes, you are my skeleton. Now come, I want to show you something” My mind was still in shock that I'm a skeleton. I don't know what to do anymore. Without knowing where we’re going, I blindly followed her through the thick forest behind us. I immediately noticed that this was not the world I live in because my world was enveloped in war. My mind was filled with questions that wants to be answered so asked her “why am I here?  Where am I? What happened?” But she never answered, she continued walking in silence until we reached a cave. *** We went inside and surprisingly a bunch of skeleton soldiers ran towards us and greeted us in front of the cave. They bowed before her as if she was their queen. We went further inside the cave and there are a lot of separating paths, it looks like a dungeon from the manga I’ve read and the further we go, the more skeleton was seen. Some of them are mining to expand their cave and some of them are building the support beams. I couldn’t believe what I saw. I was flabbergasted by this world. I can't believe that this is real. This must be a dream.   We reached a huge hall with a bunch of skeleton soldiers in a line and a throne on the back. We walked towards it and she sat on her throne majestically while I stood beside her. She called one of her skeleton soldiers and whispered to it. Suddenly, an army of skeleton came to the throne room and as they gather in the hall she talked to me, “All of this, you will become my knight and command them” I didn't know what to answer, I didn't know what to say. I was surprised by her decision that I unconsciously accepted it and right now, I command approximately 100 skeleton soldiers “WHAT THE HELL IS HAPPENING RIGHT NOW?!!! I want some answerrrsss!!! Am I forever stuck as a skeleton, forever stuck as a virgin???”
