Luckily for the group, the sudden snowstorm seems to let up after only a few hours, so they take the chance to escape the artificial sinkhole before the snowstorm worsens. Ritsuka rides on Liz Alter's back while the Lancer nimbly climbs up the silo's circular walls to reach back up to the top, while Jeannie follows closely behind by having her Blacklight swords jam themselves into the walls to act as a mobile staircase for her to run up. And in case either Liz or Ritsuka slip and fall, she can be in a position to retrieve them quickly.

No such accident happens, thankfully, so all three manage to reach the top, though Liz Alter pants hard and needs to catch her breath.

"Sorry for making you do that, are you alright?" Ritsuka asks worriedly, since this is the hardest Liz has exerted herself, as evidenced by her panting and coughing for breath.

"I-I'm - I'm fine, i-it - cough - was my idea anyway - cough cough - " Liz hacks and wheezes, forced to rest her palms against her knees. "Just - just - g-give me a minute - "

"Master, status check," Jeannie asks quickly, eyeing the environment around them. While the snowstorm has definitely lightened compared to before, it hasn't subsided completely, so there are still whipping winds and bullets of snow pelting them consistently from the perpetually dreary sky.

"It's definitely pretty cold, but I can last for now. Liz, here, let me help..."

Reaching her hands over to Liz's back, Ritsuka rests them firmly against her spine and focuses her magic into her hands, which begin to glow blue with energy. Within moments, Liz Alter feels her strained breathing and gasping for air become amazingly alleviated as her Master's mana being transferred to her directly like this rejuvenates her at a highly accelerated rate. After a minute of such mana transfer, Liz straightens up her back energetically and stretches out her arms and back.

"Whew, good to go! Where'd you learn a technique like that? That was amazing!"

"Medea Lily taught me this. Since there's a lot of Servants back in Chaldea, I wondered if there was anything I could do to help them recover more quickly, especially in these kinds of conditions," Ritsuka explains, gesturing around at the snowstorm still whirling around them. "She told me to try this - transfer mana through my hands, and apply them to a place on a Servant's body where mana can spread easily, like the spine."

"Oh ho, smart stuff. Yep, tagging along with a Master was the right choice," Liz nods to herself.

"Well, you didn't really have much of a choice, given how we met..."

"L-Let's overlook that one detail, I'm sure you won't mind doing that for me, right, Master?" Liz awkwardly asks her Master before putting her hands on her hips to focus at the task at hand. "So, what now? We got this snowstorm, and our little base is a ways off from here. Where are we headed now, Jeannie?"

"Data Center Charlie. However, weather conditions far from ideal..." Jeannie quickly runs some calculations through her head in an effort to mathematically determine their best course of action. "Retreat to safehouse, Lancer. Same plan as before: Blacklight launch for accelerated coverage."

"Got it. Do we need to get back up the hill again?" Liz sticks her thumb over her shoulder in the direction of the nearest offline cannon tower that sits at the top of the rocky hill behind them.

"Affirmat - "

A dreadful roar resonates from the distance, somewhere over the hill behind their nearest cannon tower. Actually -

"...did that just come from the tower...?" Liz asks lightly, taken back by this sudden, eerily bloodthirsty roar.

Sure enough, off in the distance above them, a door at the base of the tower gets dented from the inside out from what appears to be a massive punch, judging by the fist mark in the middle of the metal door. Then another dent the shape of a fist bangs out from the inside, then another, then another, until the combo is broken by a terrifyingly loud and rusty chainsaw blade that rips through the dented metal like construction paper and tears the door in half.

What emerges is an extremely tall man who would otherwise be described as a humanoid pile of charred muscle and flesh armed with said chainsaw. He is easily over seven feet tall, wears nothing but ripped and torn Levi's, and is armed with his signature shrieking chainsaw that takes place of his left arm. His eyes are pure red with no pupils, and a metal plate is bolted against the lower half of his head like a half-balaclava that he can't take off.

"What the actual fuck is that?" Liz Alter blankly stares at this confusing abomination of a human being at first, unable to decide where to begin describing him.

"Cataloguing new enemy type. Estimating threat level..."

Murmuring to herself, Jeannie telepathically commands one of her Blacklights to rocket forth and attack this new hostile enemy. The blade indeed flies forward, and upon reaching the chainsawed man, who is walking slowly but menacingly towards the girls, it begins to jab and point and slash at him. The chainsaw giant raises his weapon in an effort to ward away the harassing blade, which really isn't getting anything done because of just how thick the monster's skin appears to be, so Jeannie sends forth two more blades to attack.

"I don't think those ones will do the trick, Jeannie!" Ritsuka calls out in alarm, watching the swords fly towards their target. "You might wanna pull out one of the big ones you have!"

Sure enough, as soon as the two reinforcing blades reach the monster and start attacking him too, the chainsawed man lets out a bloodcurdling roar, the same one as the girls had heard coming from the cannon tower a few moments ago, and to the girls' hair-raising alarm, he breaks into a full-on charge and stampedes down the rocky hill straight to them. With how slowly he'd been walking down the hill, the drastic change in his speed forces the girls to spring into action themselves, lest they wish to get sawed to pieces at the hands of this new enemy.

"Master, stay back! No idea about this one, we just gotta get our hands dirty!" Liz Alter quickly summons her lance. "Jeannie, back me up! And don't stab me in the back 'accidentally' just because it's convenient!"

"Friendly fire is strictly prohibited," Jeannie replies matter-of-factly as she motions to the Blacklight blades floating behind her, causing them to disappear since they appear to have no effect against this particular enemy.

"Bullshit, not with how you tried to kill me in the beginning!"

"Attempted Servant termination occurred before mutual alliance was established. Your argument is invalid."

"Oh for fuck's sake!"

With no more time to banter with her fellow Servant co-worker, Elizabeth pounces forward with great speed and meets the chainsaw monster two-thirds down the hill from the cannon tower from whence the monster has come; she opts for a simple but powerful forward thrust of her deadly spear as an opening attack to test the enemy's reactions and defensive ability, and the monster, in turn sensing the danger that Liz presents to him, adequately blocks the thrust with the flat side of his weapon.

But Liz doesn't stop there. Pulling her spear back quickly as soon as it's blocked, she raises it over her head for another powerful overhead swing, aimed directly for the monster's head to split it open. This too is blocked, but Liz's strength is apparent from how close the monster's chainsaw is brought to his own forehead from the impact of Liz's overhead.

This time, however, Liz doesn't pull back her spear; she tightens her grip on her spear and continues pushing down her spear against her opponent's chainsaw. Since the monster has used the flat side of his weapon to block again, this means that she can press her advantage without worrying about the chainsaw's teeth damaging her weapon, or at least not as much.

Letting out another frantic roar, the chainsaw man uses his superior weight to shift the force of Liz's attack to the side. Sensing his intention, Liz disengages and hops backwards a short distance to stay clear of the monster's range in case he starts swinging his chainsaw wildly, and while he doesn't do that per se, he instead continues charging straight at Liz to assault her again.

Out of left field, almost literally, Jeannie flashes into view directly to the chainsaw monster's left while airborne and delivers a hard kick directly into the side of the monster's neck, causing his head to buckle left with the kick. Such a deadly kick would have immediately snapped the spine of any normal human, but for the chainsaw man, it merely causes him to stumble a bit to his right and roar again, changing his target priority onto Jeannie. Liz, who was bracing herself for the onslaught, blinks in confusion that Jeannie would enter the fight personally like this, but Jeannie wastes as little of her surprise element as possible by following up her kick with a small storm of Blacklight blades. These blades are noticeably larger than the ones she's had out during their search of the silo, and she drops her hand to command them to rain down on the monster.

This time, the blades have enough weight and mass to them that they start to pierce and cut the monster's skin as he drops to his knees and raises his arms over his head to minimize his profile and protect himself as best he can, but that's really all they can still do, and the monster snarls back at them dangerously after the blades have done their work and stick out from the rocks like spikes around or behind him.

Liz doesn't want the monster back up on his feet, so she pounces again and strikes, slamming the tip of her spear down onto the brute again, this time gripping her spear with two hands for the thrust. Again the monster blocks, but this time he's blocking on his knees. However, this standoff doesn't last long because Liz doesn't realize how closely she's put herself to her opponent and that he still has his other arm to work with, which he uses to swipe at Liz to grab her. Liz barely reacts to the monster's grab in time and pulls herself away, but the monster is also able to riposte and swings his chainsaw at Liz, knocking her own weapon out of her hands in her haste. The chainsaw giant springs back up to his feet to avoid being put in that position again, and bellowing with maddening fury, he draws his chainsaw arm back to bisect Liz in a grisly fashion.

But before he can do so, Jeannie snaps back in, at the perfect moment when the brute is at his most vulnerable by having both of his arms out to his sides and not close to his body where they can protect his vitals. Grounded this time, she sinks her small fist into the giant's stomach - the height difference between the two of them is so stark that Jeannie has to reach up past her own head to land her punch. Nevertheless, it's a terrifyingly strong hit, because her fist sinks about three inches into the monster's stomach when it connects.

The monster coughs violently, though to an onlooker like Ritsuka, it would be hard to tell that it's a cough just off how foreign and animalistic it sounds. Jeannie doesn't let up, either: she immediately jams her left fist into the same place as her right fist, causing the monster to scream with pain this time. At first wondering how the monster is yelling with pain just from getting punched, Liz then realizes the reason when Jeannie pulls her right fist back again and punches the monster a third time, because this third hit produces a sudden tear of skin that comes from behind the giant.

Out of the bottom of his spine protrudes a Blacklight blade, a particularly large one at that. The monster is stunned, retching and gargling, and his legs and knees buckle and force him to kneel due to the puncturing of his spine. Even when kneeling, he's still almost taller than Jeannie, but that's all the better: she then slams her right palm against the giant's chest, and this time, five Blacklight swords burst out from the middle of his back, clattering against the rocks and pebbles behind him in a splash of reddish-black blood.

"Lancer," she calls out, taking a step back.

"You got it."

Stepping forward, Elizabeth plunges her spear squarely through the chainsaw man's thick and burly neck. Blood pops from where his mouth should be, though due to the bolted metal plate over it, blood simply dribbles down in droves behind it and starts dripping en masse from his chin and down his neck. Liz Alter tears her spear out to the left, and before the monster can flop over, she swings it back the opposite way, and with superhuman aim and precision, she finishes the decapitation and lops the monster's head clean off.

Jeannie watches the giant's head roll for a bit on the rocks before it comes to an uneasy rest, its bloody red eyes still open and staring emptily into space. The body is still twitching, namely its right arm, but after a few moments it, too, becomes still.

"I take it that you don't know what the hell this thing is either?" Liz grumbles, gazing down at the body of their fallen opponent, and the small Servant, predictably, can offer no reply.
