My Hero Academia owned by: Toho and Bones... I think?

All Fate Series related things owned by: Type-Moon... again I think?

Look the point is I own nothing... credit the proper people for their creations... moving on.

Also to note, This is an AU where Izuku has the missing pinky toe joint indicative of a quirk potential.

I had some inspiration for this story from "Hero's of Spirit" by: Lupine Horror... (My Hero Academia crossover Fate Grand Order) ... Please check out that story.

Today had been an... unusual day for Young 4 year old Izuku Midoriya... This morning his right hand had an unusual tingling... if not occasionally burning feel to it... but it didn't hurt too bad so he decided not to mention it to his mother as they walked to school with his best friend Katsuki Bakugo and his mother. Kacchan had an amazing Quirk in Izuku's opinion, Explosion! It allowed Katsuki Bakugo, or Kacchan as Izuku called him, to sweat a nitroglycerin type fuel and ignite it to create Miniature (or massive as we see later) explosions. Izuku had not yet found his Quirk but he knew it would happen soon... how right he was.

School went fine and the two where waiting in the nearby park for their parents. Kacchan was showing off his ability to bounce the ball in the air when it took a bad bonce and went into the street. Without thinking he and Izuku ran to get only to hear the sound of an 18 Wheeler truck blast it's horn and the brakes hissing, the driver desperately trying to stop.

As time seem to slow and the certainty that they were going to die increased Izuku's right hand began to burn as it never had before and while not noticed at the time a red symbol appeared on glowing as bright as a lightbulb... and just as the truck was about to run over the duo a new figure appeared from nowhere grabbed the two in her arms and jumped to the near by sidewalk. She had Blonde and Green hair, cat ears and a cat tail.

"Uh... Green haired Master... Are you alright?" The woman clutching to Katsuki and Izuku asked.

"Y.. yeah." Izuku stuttered.

"Good... you're our Master I can't let you get hurt." She said starting to stand.

"Master what is your name?" The Woman asked.

"Izuku Midoriya." Izuku answered.

"I am Thankful I was able to save you Master Midoriya, My name is Atalanta. I am a Archer Type Servant, you are my Master because you summoned me, I will defend you with my life."Atalanta said kneeling putting a hand over her heart

"Kacchan! She must be of been summoned my Quirk!" Izuku whispered to the speechless Katsuki.

"I'm unaware what a quirk is, but if it is some kind of power or energy, it could very well be what brought me here." Atalanta said.

"How the the hell do you not know what a Quirk is!? Everyone has one!" Katsuki yelled.

By now nearby people had seen and already called for the police or ambulance. As the newly appointed Master, his servant, and His best friend Katsuki Bakugo, where talking The first responders pulled up ambulances checked the truck driver, Izuku and Katsuki, noting no seriously injuries from anyone thank goodness. They noticed that Izuku's marking on his right was glowing red, not as intense as before, but all the same glowing. They noted a continuous micro drop in stamina from Izuku, but nothing serious.. or even worth considering dangerous yet. They still advised their parents, That arrived to the scene, minutes after they identified both children, to still take them to the hospital, they also especially advised Inko Midoriya to get Izuku checked out again by a quirk specialist doctor.
