O' Sword, Let Thee Be Filled

CHAPTER 5

-

(BOOM!)

Fire erupts everywhere as Sieg bursts through the intense wall of fire without a singe in his suit. Demonic energy surges into the greatsword in his hands before he swung the blade down with ease, blackish-red energy splitting the wall of fire to reveal Riser, who barely dodged the aerial slash.

Recovering from his dodge, Riser immediately pounced onto Sieg, wielding a blade of his own as he closed the distance between them with a sprint.

(CLASH!)

Their blades clashed, sparks flying as their swords turned into a blur, the sound of their weapons clashing against one another increasing and loudening like thunder. Eventually, Sieg pushes the young Phenex away, creating distance for him to activate his Sacred Gear, the two halves of the handle between its beautiful jewel twisting, signaling the end.

Twilight illuminates the room as he swung Balmung vertically, a wave of True Ether launching from the blade at high speeds. Without any time to dodge, Riser raised his sword to guard the attack, only for it to shatter instantly upon contact with the twilight aura as a large gash appeared on his torso, blood spewing like a fountain.

Riser drops to the ground and cries in pain with his hand caressing the wound. Sieg, however, saw the tomfoolery in a flash as the child in front of him could simply heal with his bloodline magic, but decided to let the Phenex go with Balmung fading from reality since they had been sparing for over an hour now.

Riser opened one eye and looked at Sieg before sighing in relief, flopping to the ground after stabbing his sword into the ground. The slash wound on his body started to light up on fire as the gash slowly disappeared, his unique bloodline as a Phenex passively healing his wounds.

"At your current skill level, you can fight toe-to-toe against a High-Class."

"All thanks to you, Mr. Sieg!"

The now ten-year-old said with a grin before he hopped from the ground, the wound on his chest absent as if it had never been there before. Impressive as always, Sieg thought before smoothing the creases of his suit's lapel. This was one of the many butler suits that he received on his birthday last year from his Master; it would give great displeasure if he accidentally ruined it.

Using a spell to check the time, Sieg looked over at Riser.

"Our time is up. And congratulations on receiving your Evil Pieces yesterday."

The face on Riser brightens as he nods.

"Thank you! And did you hear? I got a Mutated Piece!"

Sieg's eyebrow perked as the mention of a Mutated Piece caught his interest. They were a bug in the Evil Pieces system, the one that resurrected him as a Devil, that was kept for fun by the creator, the Maou Beelzebub.

They were, on average, about 5 times stronger than a normal Evil Piece. This "bug" is rare to appear, with only 1 out of 100 Devils owning a single Mutated Piece.

"Yes, I did, one of my bishops! But I cannot decide whether or not to give Yubelluna the Mutated Piece or my Queen Piece..."

Yubelluna was one of the servants that Lord Phenex found a while back who was the same age as Riser, presumably for the young man to add to his Peerage. She had a gift in explosion magic, was loyal to Riser, and was bright for her age.

"She will be a positive addition."

He responded politely before the two parted ways, Riser ordering the servants supervising their training session to lead him back to his room while Sieg followed a servant to House Phenex's teleportation room to travel back to the small two-story home of the Leviathan in a secluded place far from cities.

The moment the teleportation spell ended and he was shifted back to his living space, he was instantly smoldered by a pair of breasts, as he already knew the culprit of said "attack.".

"SIEG! SONA HATES ME NOW! WAAAAAAAAAH!"

The Maou of Foreign Affairs started wailing as his head was steadily being crushed in between his King's chest and arms due to her immense strength as a Maou-Class Devil.

A normal Devil would have died with their heads popping, but he was no ordinary Devil, especially when his Master was... Well, his Master. He was used to it at this point; she always did this when she had an episode of her emotional moments, as he ignored the searing pain.

"What did you do this time, Master?"

He questioned with a muffled voice. Serafall simply sniffed her nose as she let him go from her death hug and pointed for him to see the object of his Master's despair.

A moment of clarity struck him. "Ah, that made some sense." was the thought that flashed in his mind.

A postcard was encased in ice made from Demonic Energy, the energy signature confirming that it was made by Serafall. The postcard was frozen at a particular angle, so he could see the contents of the postcard.

["Onee-chan, I HATE YOU!"]

The text read in large fonts, with pictures of her younger sister, Sona Sitri, wearing cute Magical Girl costumes of various colors and designs, her face redder than a Gremory's hair in every picture.

He knew those pictures. After all, he was the one who took them, with his Master forcing Sona to dress up as such. He did wonder where the rest of the pictures went, and he finally got his answer.

... Sona's English was rather advanced for a four-year-old, he mentally noted as his attention moved back to his Master.

There is a problem whenever Serafall is in her crying mode; she effectively stops her work for the whole day, something that is catastrophic to the whole Devil-kind as the only Maou responsible for foreign affairs that keeps the fragile balance between the Devil Faction and the Angel and Fallen Faction in a tight vice.

So, deploying his countermeasures to calm the Maou down, Sieg started to pat the back of his Master's head and sooth her back. She responded by hopping and wrapping her legs around his waist with her hands tight around his torso, puppy eyes staring at him.

He easily carried Serafall to the living room and placed her down gently on the couch, turning on the television facing towards them as the TV started playing the recordings of the newer Magical Girl animation that she was binge-watching, Cardcaptor Sakura.

He was about to grab a blanket from Serafall's room when she suddenly grabbed on his wrist and tugged, with him falling into the couch with her face-to-face.

The world stills as they stared into each other's eyes, their foreheads almost in contact with one another. A moment passed silently before she adjusted her grip on him and shoved his head into her chest.

"Sieg, I really lucked out. You are the best Pawn I could ever hope for."

A foreign heat surges from within to his chest when her hand caresses the back of his head gently. He hums in response, the anime on the TV acting as white noise as they both relaxed on the couch without any worries in the world.
