Normal POV
Logan grunted as Artoria's blade came down on him with relentless force. Every swing brought a flash of memory from his past—a past he thought he'd left far behind the last thing he needed was to deal with a furious Artoria but here she was (back alive somehow just like Cu) pushing him back with the sheer weight of her fury.
"Artoria dammit would you just listen—" Logan growled deflecting another blow as best he could with his claws but she would not listen.
"Do not dare call me that, Sir James," she snapped her invisible blade glinting as she brought it down again this time with renewed ferocity "you have no right to speak to me as if we are allies!"
Just as Logan felt himself reach the breaking point he heard Shirou's frantic voice break through the tension.
"Stop!" Shirou shouted throwing himself between them with his arms spread wide as if that alone could ward off the fierce Servant. Artoria's invisible blade stopped mere inches from Shirou's face, her green eyes blazing with outrage as she glared down at him.
"Master why are you standing in my way?" she demanded her voice trembling with frustration. "This man is someone you do not know a treacherous rat if anything" she continued causing Logan to inwardly wince it had hurt to hear his former friend and king to say that...but he knew that he deserved those words however not everything regarding her downfall had been entirely his fault.
"Because…he saved my life!" Shirou insisted his own eyes steady as he met her glare "the blue spandex guy killed me I should be dead, Saber but Logan-sensei was there and tried to stop him," he continued.
Artoria's glare softened but she didn't lower her sword entirely "very well Master," she finally said though her tone remained cold "but we will be having words Sir James," she added her gaze never leaving Logan's. Then turning her head slightly she muttered, "I sense another Servant nearby I shall return shortly to battle them please stay here Master."
Without another word Saber leapt onto a rooftop vanishing into the night.
Shirou looked up at Logan scratching his head in confusion "enemy servant? Master? I still don't really understand…" he trailed off but as Saber's presence faded into the distance realization dawned on him.
"Wait Battle? Saber hold on! Don't go off on your own!" Shirou ran a few steps before pausing and calling over his shoulder "come on, Logan-sensei! We've got to stop her!"
Logan let out an annoyed sigh grumbling to himself as he broke into a sprint after Shirou "just what the hell have I gotten myself into," he muttered.
They ran through the empty streets, the sound of distant clashing guiding them. Soon they spotted Rin and her Servant Archer locked in combat with Saber.
Archer though skilled was clearly struggling against Artoria's fierce strikes each one powerful enough to keep him from regaining any ground.
"Saber stop!" Shirou shouted instinctively reaching for her with his Command Seal a powerful surge of magical energy burst from his outstretched hand binding Saber in place.
At the same moment Logan leapt forward claws unsheathed blocking Saber's blade as she aimed another strike toward Archer.
"Master!" she cried shock and frustration in her voice as her blade struggled hard against Logan's adamantium claws "why are you stopping me again?"
"Because Tohsaka isn't an enemy!" Shirou answered panting as he caught up "Tohsaka goes to my school…we're not exactly friends, but…I know of her," he explained.
Logan still holding Saber's blade at bay gave a grim nod "the girl's a magus actually but she used some weird gem to revive the kid here after Cu ran him through with Gae Bolg," he added "so if nothing else, maybe back off the swords for a minute," he continued.
Saber finally lowered her weapon though her gaze remained wary Rin straightened up brushing off her red coat and flashing a coy smile.
"Good evening to you Emiya… and good evening to you again as well, Logan-sensei," Her gaze flickered briefly to Archer her expression softening before turning her attention back to the group.
"I guess we'll be having this talk of ours early huh sensei," Rin continued.
-Emiya Household plus one info dump later by Rin because I'd rather not have to type what you all already know-
"Heroic Spirits? Holy Grail Wars? Throne of Heros?" Logan questioned pinching the bridge of nose "god damn fucking magi always causing me problems at least that explains how Cu and uh...Saber over there are back again," he continued casting a hesitant glance over Saber who was sitting behind Shirou casting a burning glare at him "I am not drunk enough for this shit," he muttered despite the fact that he couldn't actually get drunk but that didn't stop him from pretending.
"In any case Emiya we need to get you checked in with the overseer but first I demand explanations from you Logan-sensei for starters who the hell are you really?!" Rin questioned placing her cup of tea down.
"I have to ask the same thing sensei because I've never seen a person grow metal claws out of their hands," Shirou added while scratching his cheek nervously.
"The question we should be asking master is who summoned him and what class servant is he," Artoria interrupted causing Shirou and Rin to send confused glances at her.
"Alright one question at a time...to start with I actually don't know how I have my claws it's just something I was born with I guess and second of all I don't go by James any more just call me Logan and finally I am not a servant I am as some would say semi-immortal," Logan explained.
"Wait! Wait! How can you be semi-immortal? Your either just immortal or you're not. Also, how the hell are you immortal sensei? Better yet how long have you been around?!" Rin exclaimed nearly leaping at him causing Logan to cringe back.
"I am technically immortal because of my insane healing factor...here watch," extending his right hand out three claws came out.
Logan then proceeded to stab himself right in the heart causing Rin and Shirou to jump while Artoria's eyes parted slightly "Logan-sensei!!" the duo exclaimed thinking he had just killed himself.
However, Logan just chuckled "oh man you kids should see the look on your faces haha but no I am not dead still alive actually," he said ripping his claws out from his chest showing the hole in his heart healing back at insane rate.
"Amazing...do you have any idea what any magus would do if they found out about you Logan-sensei?!" Rin questioned while Shirou looked a bit sick at the sight.
"Meh a lot of magi have hunted me down but so far none of them have lived to tell the tale," Logan said with a small chuckle "in any case though I've been alive since the time of the gods till the time of men," he continued.
Rin's jaws dropped "you've been around for that long?! B-but how has no one ever heard of you surely you would have been recorded down somewhere in the history books or legends," she said with wide eyes.
Artoria however suddenly gained a look of realization 'so that's how he was always able to return unscathed from those missions I sent him on!' she thought.
Logan suddenly smirked "I've been given many names by many people however I think Japan has their own records of me not as Logan or James. Tell me have you two ever heard the legend of the Sliver Samurai?" he asked.
Rin and Shirou nodded "the Silver Samurai Kenuichio Harada was once a samurai before being betrayed by his lord and he became a mercenary soon after killing his former lord he then went on to build his own criminal empire that would eventually be taken down by-" Rin stopped herself when she finally connected the dots.
"Kuzuri the so called wolf yokai...or rather I should say the Wolverine," Logan finished with a wolf like grin.
