Reincarnated as Altair in FGO

Arrival At Chaldea

Somewhere in a void

???: "Is it finally over?"

I always had bad luck no matter my life was always miserable. When I was 10 My parents and brother died in an accident I always blamed myself because I had asked them to go to a particular shop I liked my brother was always the best brother to me despite having a job that took a lot of time always cared for me. That day he had a day off so I proposed to go to that shop they wanted to go to the beach but I refused and insisted on going there at a point they agreed and we went there but it was incredibly crowded and I got lost before entering the car but suddenly as I waited for my parent's and brother to come to pick me up I heard the terrible news from the police officer that came to look for me. 

After that, we held a funeral for them and I was taken by my Grandparents they never took care of me and as I went on I continuously had terrible life moments. After 9 years I found myself a simple part-time job during the Years I immersed myself into animes there was one anime character I particularly liked her name was "Altair" from her power to her looks I loved it as I went outside after finishing my job I was pushed by something and I simply died. Was my life finally over? could I finally rest? where my last thought before being consumed by darkness.

???:' Where am I?': I woke up surrounded by darkness I couldn't move anything as I finally returned to thinking I suddenly remembered Altair.

???: I guess this is it. As I was about to close my eyes suddenly a blinding light appeared causing a lot of memory to flash in

???: Servants, Chaldea isn't that fate/Grand order? am I perhaps getting isekaid?. Soon the white flash disappeared and more memories flooded my memory as I could remember I became a servant and an avenger the best thing that made me smile was I became Altair not only do I look like her but also got her skills

Altair: Well I guess I am being summoned. I was currently trying to remember about FGO as much as I can. As I pondered about this second life cracks out of nowhere that appeared as a broken glass appeared and I waited enough time for me to pass through and make my entrance. As I stepped out I saw a lot of servants and two humans as I looked at them I said

"Avenger class Servant. Altair. Are you the one who summoned me?"

Currently at Chaldea

A certain orange-haired girl was walking along with a pink-haired girl who was currently holding a cat-like creature called fou in her hand.

Gudako: "Dammit it's been more than a year since I have summoned any new servants my brother is bragging about his luck curse my E-rank luck,"

Mash: " Don't worry senpai you can use the summoning quartz that I had saved so you can try again".

Gudako then looked at mash while crying and thanking her she then decided to go into the summoning room to try again. She continued to summon she was at her last summon as she poured her last SQ suddenly a blinding light with gold color appeared behind the card was an avenger but suddenly cracks appeared on the card rather everywhere as if reality itself was breaking like a piece of glass. Gudako immediately tells Mash to alert other servants to come to the room

Mash: Attention to all servants an unknown servant is being summoned. All available servants please come to the summoning room it may be dangerous please come to me and Gudako's location"

Instantly all the available servants started rushing to the room fast as they can. Mordred, Cuchulain, and other servants arrived as they witnessed the broken like fissure everywhere around the room. Merlin attempts his illusion magic but the fissure simps to simply repel it while 'others tried their best. Gudako could only hold Mash in order to avoid the cracks taking her suddenly a voice is heard.

"Avenger class Servant. Are you the one who summoned me?"

A servant with long white hair and piercing red eyes, which have a bluish-green box in them. She wears a dark navy-blue military hat and a Spanish-style double-breasted coat suddenly gazed at the servants then looks at the two people.
