M30, year 602, in the air, a hole tears the fabric of reality on Terra, a small naked kid appears in the middle of a house debris, it's a 7 years old Shirou, his senses return slowly, the kid listens to screams and sounds of gunfire, explosions and things breaking.

Once his eyes focus back, Shirou notices smoke going to the sky, it's afternoon and strange "futuristic" aircraft can be seen in battle crossing the sky.

It take a few moments for him to understand his situation, he is alive somehow, he is on his child body, as he was during fuyuki great fire, he was completely naked above some bricks and mortar from a damaged house, there´s some fire around too, all nearby buildings and houses aren't much better, the ones that aren't a pile of debris, are damaged or on fire.

Shirou looks around and finds some curtains and tears them, coughing briefly with the inhaled smoke, suddenly he closes his eyes briefly and tries to feel his magical circuits. His first surprise, he has more than ever, 81 circuits, only 54 "intact" and active, the rest are latent or damaged.

Besides that 81 circuits, he has a unknown number of circuit remains, that can´t be used at all, or are dangerous to use, due to how damaged or incomplete they are, his circuits have signs of damage from certain memories, like his uses of Archer arm, or from being dissolved by the grail mud, during his fight with Kotomine, probably eaten by the grail itself, they are the remaining circuits from several of his "soul fragments".

Shirou is surprised, that's good news, yet, he had to be cautious with the use of his magecraft. Besides that, Shirou notice something on his shoulder, it´s Rin´s crest, that she donated him, and stitched to it, it's his father's crest, the Emiya crest, he has a sizeable crest on his left arm, from shoulder to wrist.

A crest with some redundancy on it, his father had only 20% of his family crest, yet it seems it´s what the grail devoured it from Kiritsugu on all time lines that Angra Manyu curse killed him, it's a large redundant crest, with damaged edges, that were being consumed slowly by the greater "multiversal" grail. The composite Tohsaka-Emiya crest was large and had some redundancy, itching a little due to the small remains of an implant rejection.

His body was slightly burned, he could feel Avalon inside him, quickly healing his wounds, stronger than ever, the multiple instances of the relic fused, and overcharged, the massive excess magical energy stored on it, it helped strengthen and protect its "mystery" and keep the reinforced physical relic strong, even on another reality.

He was starving, but healthy, some parts of his skin were "tanned", his memories from Archer and from the universe he had a sister called "Miyu" informed him it was some sort of "collateral" from his magecraft, as his hair had a single lock of white hair.

His right arm had various command spells, it seems all unused command spells, that usually return to the grail, were absorbed by him too, he could feel a faint connection with Saber, and Rin, Saber current master and anchor to the world, it was similar to how Sakura and Shinji shared Rider.

Rin had her last ditch familiar contract with Saber, Shirou recovered all unused command spells and recovered his half of the connection, he could try mental conversation with her, through the command spells, like he could do with Saber, but he was busy at the moment, yet, it made him happy know that.

"-...Trace on..."

The gun hammer fires on his mind, activating his 27 most healthy magical circuits. His projection altered the curtains into clothes, he kept walking through the debris, found leather from furniture and rubber, used it to make boots and ended with light brown pants, white shirt, and boots.

The kid made a backpack and a mantle with hood to cover himself, the sounds of battle kept on. Despiste the lessons from the memories, this still was a Shirou determined to be a hero, but not a "fool" like he usually would be, he noticed his situation and thought properly.

"- It's not safe here, I should help but, with this body... I need to know where I am, contact Tohsaka and Saber, know if they did destroy the grail properly, if they are safe..."

He mutters to himself, smirking at how his "inner dialogue" was spoken, like a little kid talking with himself would, a lapse maybe? Or maybe his child body and undeveloped brain would make him act more childish? He had no idea.

"- ...Trace On... Analisis complete..."

The use his structural analysis to see if there's anyone under the debris he awoke, he find bodies, too late to be saved, he sigh and walk through the streets of something that resemble a middle east city, on a desert, he see many damaged buildings, fire and demolished buildings, like the one he woke up.
