Reincarnated As A Bat

I have always been friendless, I have always been ambitious at my studies and my goal, I never cared about anything else but... There has always been something at the bottom of my heart... that I want to be better. Mizuto Sato a student who has always been ambitious and lonely, since kindergarten a best friend of his died in a car accident and ever since then he wants to continue to move forward. But he just couldn't accept and to forget the memories of the past, so he decided to never be friends again, he can't afford to lose someone else, he had never met his parents and was raised by his uncle since that tragic accident. •••• It was October 1, 2015 Today was the anniversary of my parents death, I went to the cemetery where my parents were burried. [ May you rest peacefully in death. Mom, Dad. ?? ] - I said I left the cemetery and While I was walking back home I am starting to feel tired, maybe it was lack of sleep or is it something else, I started to feel sleepy, It seems like I fainted, I'm starting to feel pain all of a sudden. While enduring the pain I am starting to hear talking, I can't fully understand what their saying but I hope it's not something serious about my condition, I slowly opened my eyes I can see two people talking. [ Thankgoodness you're awake! ] [ Don't worry! We'll do everything we can! ] Shut up! You people are so noisy I can hear you two loudly. I closed my eyes again and somehow my body feels Wierd. My body is heavy. It seems like my body feels strange. I tried opening my eyes, My sight is quite blurry. A Light?! Is this my end? Is this really happening? My body feels Wierd, I can't move properly so I'll just have to crawl until I get to it, I blinked three times and it seems like I am outside the hospital. I slowly raised my hands. [ Wings?! ] [ Why do I have wings?, Could it be that... I'm a bat?! ] [ Unacceptable! There's no way this can happen. ] It seems like I have died and now I reincarnated in another world as a bat? I'm not an Otaku or a Isekai expert but I do know how to survive in a Forest, although this time I'm a bat.
