SHORT SUMMARY:

Manna summoned Cu Chulainn from a parallel verse to her side, to aid her in destroying the Holy Grail and save other Servants if possible. They entered the area of Fuyuki City which was the battleground area for Servants.


Manna and her Servant Lancer were standing at an abandoned industrial area. It was a lightly cloudy night, yet the moon shone bright.

Manna took Cu Chulainn's hand into her own, closed her eyes and spoke:
»May your pockets be heavy, may your heart be light. May good luck pursue you each morning and night.«

It was an old Irish blessing. Knowing Lancers had bad luck, she feared for him and hoped to share some of her seemingly infinite affinity for it.

Cu mazed when he heard the saying from her.

»Trying to be my personal good luck charm, are you?« He grinned as the girl looked at him with sparks in her eyes.

He would put his hands on her cheeks and kiss her.

He kissed her for a long time before parting his lips. He looked around, scanning the area.

»Don't worry. I'm winning this one for you.« he said.

She stared at him and a vision of the future played in her mind. Her eyes went out of focus as she saw this.

Cu saw her looking straight through him.

She saw Lancer's fight. He was at a disadvantage. She needed to find a frame of chance. As soon as she thought that, she had found it. A moment of confusion which would cost their enemy their victory.

Her eyes sparked once more when she pushed the vision away.

»Yes.« she said lovingly, looking at her Lancer.

»Be safe.« she said and Lancer had to smile.

The girl knew she was helplessly in love. Even more so because her lovely Servant had returned his affection to her.

Cu began to walk away, where the enemy would be.

She stayed behind in the still area.

She sat down on her knees and put a magical barrier around herself in a form of a white semi-transparent bubble. It was a skill unique to her. A protection that could not be penetrated by any attack.

She closed her eyes so she could watch her Lancer fight.

She had been sitting there for about 15 minutes as the fight went on.

She didn't notice that her glowing spell had attracted an enemy.

Caster, a rotten woman by heart, had appeared behind her, after circling the girl unvisibly a few times prior.

»An interesting shield.« she spoke. »I would love to add it to my collection.«

She thrusted her spell-breaking dagger into the magic shield and her heart squeezed in pain when it had absolutely no effect.

Even more, the girl inside didn't flinch or made any sort of notice of her.

She presumed to throw every possible attack at the young mage, all to no avail.

»If I can't break it, I will take it.« she said angily and decided to lift the ground under the mage and take her along within her bubble and the space surrounding her. Back in her castle, she would have plenty of time to fiddle with the girl's spell.

Manna opened her eyes as she felt a deep tremor.

She turned to see a cloaked lady staring at her in rage.

She could see the residues of the spells Caster had used to attack her while she was out.

»Hello. I didn't see you there.« the young girl said.

Caster gritted her teeth, thinking of it as mockery. Where the girl was being honest. She didn't notice anything at all whilst watching her Lancer in a trance.

»Heh, your defense may be superb, but you can't control the space outside it, can you?« The Caster woman spoke evilly.

Manna saw the ground beneath crumble and trying to lift up under her. She disliked it. She disliked the woman's evil grin and her foul death-colored magic.

Her mind went dark in tandem with her heart and she decided to follow it for the moment. Her usually angelic sweet face and eyes went sharp and dark.
She let her defenses slightly fade. She assumed the Caster woman would not notice. As she did that, her protective ball changed color to a dark grey, as the white light seeped out of the bubble , forming long, shining tentacles.

»Do not disturb me.« Manna growled lowly and a tentacle shot out and wrapped itself around Caster's neck.

She would have played with her like a cat with its' mouse. She much desired to do so, as her instincts implied. But with her defenses being down, she couldn't afford it.

The tentacle around Caster's neck coiled itself together in a swift movement, breaking the woman's neck within a second.

Caster's head fell slightly sideways and with a tremor her spell, that she was casting, broke apart.

Manna could feel her Master's shock, as he failed to call his Caster Servant back in time.

She loosened up her tentacle and let Caster's body lay on the floor.
She kept the tentacle around her neck, to supply the body with mana, so her body would not disappear. She wanted to show her catch to her Lancer.

After a long while Cu appeared before his Master with a proud yet painful grin on his face.
»Servant Rider has been defeated.«

She smiled and looked at his wounds with a bit of concern. She knew he was indeed durable but his left shoulder and right thigh were pretty minced up. It looked painful.

Cu waited for her to scold him.

»Good job, I am so proud of you, Lancer.«

Lancer was surprised when she praised him.

»I actually got one too.« She lifted Caster's body off the floor by the neck, showing off her kill.
»I hope you're not angry.«
Surely Cu took the other Servants as no joke, and to have her killing one so easily... she thought Lancer would think she was letting him fight out of pity, as in certain terms she was much stronger than him.

»That is pretty amazing.« Cu stared in surprise.

»It was only fair. A magic user versus a magic user.« Manna said and smiled when she saw her dear Lancer was pure-minded indeed.

She uncoiled the tentacle from the woman's neck and her body disapeared before even falling to the ground.

She returned her eyes to her Servant's wounds. If Cu had hoped to avoid getting a lecture about it, he now just wanted to cover his ears.

»I'm fine. It's not that bad.« he quickly began to defend himself.

»Okay. Let's get you healed.« Manna smiled, and the energy from her bubble shield began to fill around her palms in a form of two glowing orbs.

As swift as a flash, a shadow appeared behind Manna. She could smell a strong, recognizable scent but a moment before an excruciating pain immobilized her body.

Cu Chulainn stared as a figure in dark green clothing appeared behind Manna and reacted but a second too late, upon realizing it was an enemy Servant.

Manna looked down and saw a sharp object poking through her chest. Her protection spell was still in effect, yet something had pierced through it.
»Cursed spear.« she groans before falling unconscious due to the immense pain of having her heart impaled.

The enemy Lancer pulled his spear out of the girl.
»Please forgive my foul assault.« He spoke bitterly, finding it disgusting to stab an opponent in the back. »Master's orders. She was far too dangerous to be left alone.«

Diarmuid looked at the girl that was lying on the ground, her back getting soaked with blood.

This girl. She took down Caster by herself. He had seen it. He then observed her for a while.
He didn't believe his cursed spear could disspell her magic field, but his Master had ordered it nonetheless. He could not disobey.

Cu's mouth dropped open before his face distorted with anger and a deep cry from his throat echoed in the quiet of the night.

»You... foul rodent!« he growled at Diarmuid and his eyes glowed blood-red.

He charged at the enemy Servant, who blocked him with his two spears. Diarmuid furrowed his brows. This Lancer Servant was strong. It took all of his strength to only stop one blow.

Cu had but only thought on his mind: To kill the man. He growled and focused on his spear that glowed red as its Noble Phantasm activated.

Diarmuid felt the overwhelming power. Hard to think that the other would use his Noble Phantasm right after a battle with another Servant. He was summoned back by his Master, just before Cu's channelling had reached its peak and he would have thrusted his spear at Diarmuid. Cu screamed as the enemy Servant vanished before his eyes and he stabbed his spear into the ground in rage. The ground under it crumbled and burned.

He left his spear in the ground and turned with horror on his face.

His Master's protective field had disappeared.

At least he could touch her now. But this indeed was grave. The field would normally not disappear even as she slept. In fact, then it would only be stronger.

Was she dead? Was she dying?

He knelt down and turned her around, then held her in his laps.

'Mana. A healer. Something. I need something!' He thought in panic and leaned his ear next to her chest. He couldn't tell whether she was still breathing or if her heart was beating because his own was rushing.

He glanced at his spear, that was sticking from the ground. It disappeared before he himself disappeared with the girl in his arms.
