Saying nothing Hiro watched his sister move forward with his blessing. With light steps, Tsugumi skipped toward her husbands and her sisters-in-law. A harem is already a selfish thing. No matter how one justifies it, harems break the very notion of fidelity.

As such, if one wishes to gain one, the dominant must become one who justifies having an army of lovers. Admitting that harems are selfish and do not make sense is the first step to making them better. Since your harem members already give you their everything, the least you can do is make them happy.

If it was hard to ensure the happiness of a single person, then no matter how impossible, the harem seeker must fulfill such an arduous task of pleasing his or her entire harem. This could be considered the absolute minimum if one wished to have multiple partners.

Tsugumi sided with her husbands as she addressed her sisters. "Onee-samas, I thank you for cherishing me so, but my hubbies are not cowardly nor are they spineless weaklings. They love me and I them, how we address our affairs is our own. I understand how important this duel is for you but I similarly cannot lose."

Hiro then walked and address them all. "With our matters finalized then we will proceed with our first duel. In order to make it official Tsugumi come here." Tsugumi stepped forward and stood in front of Hiro.

- Alert: You are about to enter the Heavenly Sword battle harem under Hiroto Musashi as a Gladius Paramour rank Submissive. –

- Do you accept? YES | NO -

Tsugumi who received the alert felt extremely happy. She wanted something tangible to say she and her brother were part of the same family. Thus she secretly couldn't wait to ask when she could join his battle harem. She couldn't contain her excitement now that the invite was in front of her.

"Nii-sama, a Paramour? Incest is bad you know? And I cringe at the thought of spending my days with you."

"Shut up Tsugumi, I only have 10% to spare, I am giving you 7% so keep quiet and be grateful."

The more she heard the more Tsugumi knew her brother always kept her at the back of his mind. To some 7% was little, but coming from a dog rank from the Hand of Shadows. To her, 7% meant the world. Tsugumi knew how much he loved her sisters in law, thus she was fine thinking they got a whopping 90% of his domination link.

As she thought about it the remaining 3% was already spoken for. It seemed his brother was serious. He had no intention of getting anyone else. This was both his conviction and his proof of how much he loved his wives.

Inwardly Tsugumi planned to copy her beloved brother. If her men were already hurt just from having a third of her time. How would they feel if she added more the longer her years went on? As years pass the discontentment would rear its ugly head leading to separation or divorce.

Hopefully, she prayed to the [Creator] that the love of her hubbies would allow them to share. She would do anything and everything to make it so. As she indicated her willingness Hiro started to speak his vow.

"I Hiroyuki Mitsurugi, Vow to uphold your honor and give you both my affection and trust. As Dominant I grant the Gladius Paramour rank title to Tsugumi Mitsurugi to be my ally until death does us part or our trust be broken.

"I desire for you to find your happiness and for your heart to be cherished. So long as my heart beats I will love and protect you as your Brother. This I swear on my life and my sword."

- Confirmed. -

At Hiro's vow Tsugumi was already in tears, long has she dreamed of this moment; after suffering so much hardship, she now finally belonged to her brother's household. With a shaky voice, she spoke her oath.

"I Tsugumi Mitsurugi, vow to defend your honor and your heart. My love and my sword will never turn against you. No matter what may stand before our horizon, be it a storm that knows no end or calamities that seem insurmountable. My candle shall forever burn beside you in this life and the next."

- Please choose the Offering for your Dominant (Hiroyuki Mitsurugi |Hiroto Musashi) –

- Warning: The Offering is a percentage of the Submissive's power based on available attributes. Once accepted, the stat percentage cannot be revoked by the Submissive. If the Link is destroyed willingly or unwillingly. The stats cannot be recovered. –

-Warning: Offerings above 25% will cause harm to the Submissives once the Link is broken and are irreversible. –

- Proceed? YES | NO –

- Confirmed. -

- Alert: Please indicate the percentage of Offering –

- Alert: Offering Rank table. –

=100% - Enslaved

>90% - Captive

>75% - Junkie

>50% - Affectionate

>25% - Servant

>10% - Follower

- Alert: Please indicate the percentage of Offering –

- Alert: Confirm with offering: Affectionate –

- Confirmed -

- Alert: Submissive Tsugumi Mitsurugi has chosen to offer 55% thereby entering the Affectionate rank. –

Hiro who saw the offering nodded in approval. This percentage ensured even if Hiro died Tsugumi will incur injuries but would not perish. That danger existed with first-generation links. If multiple generations used Enslaved. If the dom dies, all of subs will follow as well.historical

- Alert: Dominant Hiroyuki Mitsurugi |Hiroto Musashi has accepted the offering. Domination Link will now be created. –

Lighting made from pure energy came from brother and sister and shackled themselves forming a chain.

- Alert: Domination link between Dominant and Submissive established. The system will now proceed to calibration. –

Hiro who always had calibrations that were catastrophic in nature inwardly panicked. He prepared his skills to be invoked as needed should the worse come to pass.

In comparison to her sisters-in-law, the light show for Tsugumi's binding only looked like an EDM concert. After a few seconds, the Mitsurugi Siblings saw the success of the link.

- Alert: Domination link between Dominant and Submissive Calibrated binding ceremony completed -

When the binding completed the lightning bridge dissipated from view like fading out of existence. But both Hiro and Tsugumi knew, of their bond and their link. Tsugumi then leaped to embrace her brother and asked in a cheerful tone.

"Oh, that's right brother. Whose chain does heavenly sword belong to? What generation am I?"

Hiro then created a mind screen from pure Spirit that enclosed Hiro, his wives, Tsugumi, and the San-Baka.

"I am a chain. I am the eighth, you and your sisters are first-generation links."

At this comment, not only Tsugumi but even the San-Baka exclaimed.

"WHAT?!"

Battle harems operated like pyramid schemes. The ones at the top got the most rewards. Grand Dominants or those one generation above had a tax on the offering of Submissives. This was nailed at 2% per sub, generations farther from the dominant would have 1% deducted.

1% may seem small but if you were say the 54th generation, the 1% of each generation quickly added up. As they are percent based the offering would drop to zero. However, it is a known fact that on some famous chains most of the time the offering tax is even larger than what the dominant would receive.

Thus being the first ones to join a chain naturally granted amazing benefits. Should more people come under heavenly sword, Tsugumi and her sisters-in-law would rake in an unlimited number of stats. This was of course provided they made sub-harems beneath them.
