Battle Harem of the Heavenly Sword

The dawn before Hiro's hunt, the transmigrator woke to see the women originally around him have all disappeared. When he focused on his hearing, the continuous rhythm of a hammer striking something metallic entered his ears.

He got up, made the bed, and walked out to the backyard. Voices could be heard even before he approached.

"Lene you are sure about this? We aren't even sure if it would work. Please reconsider."

"We already had this conversation, Nessa. Jei, continue grafting the array. We only have one shot."

"Ugh. Hurry. Coding difficult."

"But I'm not even an official Alchemy apprentice, writing runes for me is too much."

"So? I'm not even an official blacksmith, I'm just a striker, one of those who hammer ore. Jade isn't even an Array Technician, just a coder. What have you got to lose?"

"Shrimp. Stop being chicken. You worry. We know. We all do. We cannot lose him. No matter what."

"But this is already good enough as it is. If I fail the entire thing will melt."

"Trust you./ I trust you, Nessa."

"You guys…"

Raylene continued to grunt as she hammered with all her strength. "I trust your feelings for Darling. I know you would give your all. And If it increases his chances of returning even a tiny bit it is worth the risk."

"Stop talking. Hurry." Jade who started to falter had her hands out while magic pulses entered a magic circle. The circle was drawn around the longsword being worked by Lene.

The mage was grafting a magic array onto the weapon. The array would grant it an additional ability, if combined with Raylene's magic smithing the ability would be even better.

Magic smithing required aura, so Raylene made the metal heat up initially by furnace then ignited her aura to go even hotter.

The blade glowed brown from the intense temperature but had blue lines along the entire weapon which prevented it from melting.

Seeing the trust and determination of her sisters Vanessa then took out a vial of liquid and a knife. She then pour the vial's contents into the knife and invoked her spirit. "I understand. Then I will no longer falter."

Hiro then saw what could only be seen as ghosts from the surroundings gathering towards the knife's tip. The entire thing looked surreal when combined with the flames coming from Raylene's hammer and the blue magic circle being fueled by Jade.

The Transmigrator shed tears silently as he saw how much his girls loved him. He wanted to help but knew showing up will only serve to deter their efforts. Vanessa then desperately chanted.

"Wraiths of those who fell and arose, by my caliber follow my guidance and engrave your wrath and fury on this blade! I BEG YOU! GRANT MY BELOVED STRENGTH!"

She then approached Lene who was still hammering and started writing an ancient script on the weapon. Her eyes, ears, and nose started to bleed as she endured the feelings of the dead.

Aura used the body's inner chi, Mana uses the person's latent Psionic potential. Spirit was the only resource that required willpower. It used the strength of those who have already passed and those yet to be born. When one takes in their strength, one also needs to endure their sorrows, rage, and regret.

The whirlwind of emotions causes those who lack the willpower to become slothful due to conflicting memories. Ultimately they become apathetic to the entire world. Nessa who knew this normally used rune engraving only when absolutely necessary. The reasons being the backlash hurt like hell and left her in tatters afterwards.

The rune engraving then promptly began while Lene hammered and Jade reinforced the metal and coded an array. Aura, Spirit, and Mana worked in concert as each fortified or created something new in the sword.

After a few minutes, there was only silence. Jade fell to the floor face first, convulsing from mana deprivation. Raylene fell backward as her body acquired a fever from fatigue from aura overuse. Vanessa, who wiped the blood from her eyes then checked the newly forged weapon in high spirits, exclaiming in a hoarse voice.

"Sisters! We succeeded! With this that Manticore is toast! We actually succeeded! Where is Hiro-sama!? We need to show it to him..." As relief flooded her, the maid couldn't continue her words and abruptly fell unconscious.

Hiro then walked forward and picked up his wives, he cleaned their wounds and gave them the overdrive canceler via a kiss. He even ripped apart Jade's bandages to do so. The mage deliriously wanted to kill herself as she rebuked him and cried, Raylene, angry without reason punched his face repeatedly. On the other hand, Vanessa became like a doll that wouldn't move.

Thanking them in his heart, he then carried each of them into the bed in princess carries. Upon returning to the backyard he then looked at the weapon his family made for him with blood, sweat, and determination.

The weapon looked unlike a European longsword but gravitated towards an eastern blade, it lacked a cross guard but had a wolf's mouth as the hand guard. The blade glowed black as the first rays of sunlight shone upon it.

Seeing the abilities of the sword, Hiro could only stare in admiration at his harem. When they were discussing how to kill a dragon the greatest problem arose from its defenses. Due to not having the time or funds to create a better weapon, they instead focused on one thing.

"Pierce It."

Jade's explanation covered their entire strategy. One didn't need to shatter or cut apart the armor. Just break through one point.

Thus [Sword Driver], [Weight Canceler] and the two runes all were designed for one thing. To allow the sword to deliver as much power and damage into a specific point.
