I do not own Halo or Touhou Project, this is also an AU.

HALO: End of Touhou

Marisa Kirasame

Witch, thief, messy beyond imagining, but is quick thinking, loyal, and much more.

Now she is wounded and running.

It had all happened so fast, too fast for her to have even imagined.

Reimu was dead, dead and gone, but the Hakurei barrier still stood.

Or should we say the 'Moriya' barrier still stood.

It had all been a violent plot, the god of the Moriya shrine Kanako Yasaka, had created a plot and had killed Reimu while absorbing the power from the Hakurei shrine and now gained more power than ever before.

She also got everyone she could in on it.

The residents of the Scarlet Devil Mansion, the people of Makai, the dwellers of hell even Satori and her pets, she got everyone she could and got them on her side, even Yuyuko and by extension Yukari.

The only one left was Marisa and the only other person who was with her the whole time.

Her closest friend, arguing partner, and master puppeteer, Alice Margatroid.

They had run into a deep area, Marisa close to death and Alice helping her.

They ended up finding something in the cave, and this is where the story is in their hands.

"What the heck is that," said Alice as she saw the door.

It was massive, and made of a shining metal that looked more advanced than anything that could have ever been made, and it pulsed with energy that she could not recognize.

Then she heard them coming, they would be there soon.

Then Marisa stirred, and her hand slowly came up, trying to touch Alice's face but instead touched a glowing panel, and then a pulse of pure energy spread through the door, and then ….

….. it opened.

Within was a massive machine, with a large whirling sphere and then suddenly the sphere started to spin ….

Slowly at first, then faster, faster and faster until energy spread from it, this energy bathing Alice and Marisa and surrounding them, whoever it was who was chasing them had just entered but were pushed back by the energy.

Alice clung to Marisa, who in turn held Alice as tight as she could, even with the large amount of blood seeping out.

Then there was a massive flash of light.

A bright flash of blue light blasted out from a mountain, and then in a massive explosion of energy, the whole mountain an anything within ten miles …..

…. was vaporized.

The ones after Marisa and Alice had been a lynch mob from the human village along with a few magicians, but now they were nothing as nothing was left, they had been completely destroyed.

However no souls appeared at the Sanzu river, none at all.

The mob had been completely and utterly, erased from existence (along with some of the fairies who were near the mountain at the time).

As for Alice and Marisa, they were gone, not dead but gone.

To where, was the only real question.
