"You know Assassin, your lack of honor is irritating. Innocent bystanders are meant to be left alone. Whoever your master is will be severely punished for violating the basic rules of this grail war." She used her large weapon to shield herself.
"Hah, such trivial pride that you call honor is a glaring weakness! My master has no idea what I'm doing. She would likely stop me if she did. She wanted no part in this conflict. So to get what I desire requires success by any means. You talk far too much, prepare to die!" With a display of impressive speed he charged Saber.
Armored arm met invisible blade with the ring of metal. Assassin smiled beneath his mask as he raised his knee making contact with the shorter woman's head while her arms were busy stopping his claw. Blood sprayed as her nose broke with a dull crunch. He turned the hit into a back flip as backed off.
Saber was dazed for a moment as she saw stars of light. Fortunately, the taller man retreated rather than following up on his blow. She chased him with resolve managing to draw blood as the sword opened up a wound from gut to chest. The enemy gave no sign of his pain, but she knew he felt that. 'Curses it was too shallow!' Her mind swirled with possible counters as he met her once more in close quarters. He was truly an impressive combatant. Over and over the Servants made progress against each other. The damage was growing more severe as the battle continued.
'Damn you, looks like my ultimate technique is the only way!' He gained some distance and activated his Noble Phantasm before she could stop him. "Zabaniya, delusional heartbeat!" Suddenly, a mirror appeared in front of him perfectly reflecting Sabre's appearance. Then his arm's true form was revealed. It gleamed with a red purple light. The inhuman limb reached into the mirror and drew a still beating heart from the image.
She had no time to think as she felt pressure in her chest. The blonde began to cough up blood as the pain increased. Then she hurled her sword with all the strength and accuracy she could manage. 'God help her it worked.' Soon the vise in her chest stopped as the now revealed Excaliber pierced her enemies heart and continued on to skid across the ground.
Assassin disappeared in a spray of blood and shadow. Sabre puked up blood and crawled towards her golden blade. She had to hide it before someone could identify it. In the end she collapsed over it as her master arrived. "Hassan of the cursed arm is no more!" She smiled weakly then passed out at Rin's feet.
The brunette placed a healing item on her servant and smiled while no one could see. "Well done Sabre, we're closer to our goal now."
In a secure location...
"Finally, you did something useful old man of the mountain. I never would have guessed King Arthur was a woman, clever girl." A beautiful woman laughed with maniacal glee. She leaned on a staff as she observed a battle between servants. The conclusion revealed an unmistakable sword. The fact that Sabre wielded it was proof that she was once the ruler of Camelot. 'Hmm, time to plan a fitting welcome for royalty.' Caster laughed again as she moved away from her crystal ball.
Nurses Office Homohora Academy...
Rider gently placed the unconscious girl in a bed. Then he closed his eyes and concentrated. "Lady Sheikah, your assistance is needed in the medic room!" He waited patiently for a telepathic response.
"Alright Rider, I am coming with all haste!" Zelda thought up a reasonable excuse to see the nurse and walked quickly to where she was called.
The foreign mage arrived after a few minutes. She was surprised as she flipped her long hair over her shoulder. "Himuro-kun, oh no! Rider what happened, why is my classmate in this state?"
"I'm sorry I don't know everything. However, from what I could tell Assassin drained her of almost all her undeveloped mana circuits." He looked over at his charge and glared at his hands. He was almost certain if he had been incarnated as a Caster he could handle the girls recovery. His memory was fuzzy on the subject. He felt like his soul had the capacity for all seven classes. Though their strength varied quite a bit.
He addressed his master after his few seconds of stray thoughts. "Tell me Lady Sheikah, do you know Farore's Wind or Nayru's Grace?"
"I choose the path of wisdom during my training. So I did learn Nayru's Grace. Though I've only ever used it on minor injuries." She looked nervous as her hands began to glow with blue energy. Rider hardly asked her for anything. She felt highly motivated to show him how capable she could be. She felt drained from using it on such a dangerous wound. However, as she felt Himuro-kun's ragged breathing stabilize she felt relieved.
Rider let out a sigh of relief. "Thank goodness, now I have to help Sabre if I can." He stood gracefully and glanced at his master. Please stay here with her Lady Sheikah. Assassin is very dangerous and likes exploiting weaknesses."
Zelda let out a gasp of surprise as she saw the shield on his back. "Oh my Goddesses, that's the dragon forged Hylian Shield! Rider your him aren't you. The one who slew the desert king!"
He turned back to her from the doorway. "Please Zelda don't say anymore! We might be under surveillance remember!"
She visibly shrunk with embarrassment. "Sorry Rider, I just never expected to meet the one that saved our people." Reguardless she was happy to hear her name on his lips.
"It's alright, we'll have to discuss this later. Preferably in a much more secure location." He looked at her with determination. "For now I owe Sabre some backup." He ran out of the room with all the speed he could muster.
Rider skid to a stop suddenly as he felt a Noble Phantasm occur. Soon he found more speed was possible than he thought. He supposed being a Rider had advantages. Someone probably lost their place in the Grail War. If Assassin won he had to stop him from escaping. He really hoped Sabre was victorious. Riders were more vulnerable to Assassins after all. Also, he admitted to himself the blonde knight had earned his respect.
