An Ex-Machina on a Dimensional Journey

"Oh my~ Little Jack doesn't want dinner tonight?"

The girl named Jack shook her head, an innocent smile on her face.

"An enemy has found us."

Purple magical energy instantly covered her body. In the blink of an eye, her pure-white dress became a slightly oversized black bodysuit.

Clearly, the girl was no ordinary person. She was a Servant in this Holy Grail War: Assassin of Black, whose true name was Jack the Ripper.

And the woman beside her was not her real mother.

Rin Tohsaka was the woman's name, and she was Assassin's Master.

Seeing that Jack was ready to fight, Rin Tohsaka quickly understood the situation.

"Is the enemy strong?"

She asked nothing more. She trusted her Servant completely.

"I don't know. But for your safety, Mommy, you should go back first."

"Then Mommy will go straight 'home.' I'll make your favorite hamburg steak and wait for you."

"Okay!"

Jack leaped into the alley beside her, her small figure vanishing into the night in an instant.

After Jack made her move, an eerie mist suddenly filled the town's streets and alleys. In moments, thick fog had swallowed a vast swath of the town.

This was, of course, Assassin of Black's doing.

The fog that had engulfed the town came from her Noble Phantasm, The Mist.

It was a bounded-field Noble Phantasm that used magical energy to produce a dense sulfuric-acid fog. An ordinary person who entered it would die within seconds.

A Magus would not die immediately, but the Poison Mist would continue to harm them and interfere with their magecraft. Without prompt countermeasures, death was inevitable.

Servants could withstand the damage, though the Poison Mist would still affect them.

The Noble Phantasm's user could choose whom the fog affected. Jack could make it avoid people
