The sealed box

The warm rays of the sun cast a bright glow on the residence, illuminating the exterior walls and highlighting the intricate details of the architecture. The sunlight brings a sense of warmth and vitality to the space, making it feel inviting and welcoming.

Three shinobis are sitting cross-legged near each other inside one of the rooms

Muzina is sitting while holding a sealed box, beside him are two Jonin rank shinobi one is Miss Jonin of the Hyuga clan, and the other one has red hair and is the best medic in town he enslaved earlier that day

"Are you ready?" he looked at the two Jonins. "Are you sure about this?" Miss Jonin asked. "If we fail, we will just run away"

Mizuna's heart is racing filled with doubts and anticipation. He took a deep breath, his eyes fixed on the sealed box he was holding, as he mentally rehearsed the words he would say and the actions he would take. With each passing moment, his resolve grew stronger, and his fear began to dissipate, replaced by a sense of determination and a quiet confidence that propelled him forward.

Mizuna closed his eyes and opened them not long after and stared at the sealed palm size box

"I'm gonna start now, Sharingan"

As Mizuna stared at the sealed box, a pair of ominous red eyes stared back at him

The ominous red eyes of the beast are a menacing and foreboding sight, radiating an aura of malevolent intent and primal power.

Like two burning coals, they gleam with an otherworldly intensity, seeming to pierce through the darkness and fix their gaze on the observer with an unblinking, unyielding stare.

The red hue itself is a sign of fury and bloodlust as if the very essence of the beast's ferocity has been distilled into its gaze.

[System]

[The host is trying to control this target's mind using Sharingan, do you want to use Sharingan with Mind control?]

[Yes or No]

"Yes"

[Applying Sharingan with mind control]

[Progress: 1%..3%..5%..7%.9%.12%..15%..18%..23%.26%..28%..31%..]

Miss Jonin, and the best medic in Tanzaku Quarters noticed Mizuna's complexion that's starting to get paler and paler. They looked at each other and nodded

The two Jonins used their medical ninjutsu and converted their chakra into life force and then transferred it to Mizuna

Mizuna who was staring at the sealed box with blood-red eyes started feeling relief from the life force the two were passing into him

[Progress: 40%..43%..47%..50%..53%..55%..59%..63%..67%..69%..73%..76%..]

The two Jonin started to become sweaty and seemed to be struggling to keep converting their chakra into life force

[Progress: 80%.83%..90%..94%..99%..100]

[*Ding*]

[Congratulations for acquiring one slave]

[First slave beast achievement reward: 1 year's worth of Chakra]

Mizuna closed his eyes and let down his guard "You can stop now, thank you" he said to the two Jonin dripping with sweat with a smile

They smiled back and said "Congratulations on taming the tailed beasts"

Hiyori, Kimi and the other resident barge in and congratulated him

Hiyori hugged his son and said "I was so worried, don't do something so risky again"

Kimi who was looking at the sealed box said "So what are we gonna do with it?"

Mizuna started peeling the seal of the box containing the tailed beasts. Hiyori then grabbed his hand and said "Son don't release it here, you'll kill everyone"

Mizuna shook his head and smiled while looking at her "Dont worry mother, everything will be fine" then kissed her cheeks

After peeling off one of the seals using a hand covered by chakra, red strings of gas seemingly to be chakra started coming out of it and went straight to Mizuna's body

He closed his eyes and looked deep into his consciousness and there he saw darkness.

As he walked through it he stopped when he saw a monster's red eyes gleaming with an otherworldly intensity, its presence seemed to fill the dark air with an unspeakable malevolence.

Mizuna then said "You will become my partner from now on Chomei" while smiling sincerely

The area where the two are talking becomes illuminated by a bright light coming from Chomei's body

Chomei looks like a dragonfly wearing grey armour but its wings are seven and located at the lower part of its body, it also has 6 long arms

"Yes" Chomei replied

Mizuna opened his eyes and saw the Hyugas, a Uchiha, and the Senjus staring at him

"Did you succeed? "

He stood up and said "Chomei do it" his body started being enveloped by thick dark red chakra filled with blood lust.

The blood-red chakra covering his hands became sharp claws, and seven blood-red tails appeared from his back. His white changed to red with a black pinwheel on them

The stone floor below him cracked and the air is filled with ominous chakra seemingly looking for death and carnage

All the shinobi inside the room instinctively take a few steps back including the Senjus

Kimi who noticed not his beastly appearance but the changes in his eyes covered her mouth and said "Mingekyo Sharingan"

While Toka Senju with shock on her face said "He-He fully controlled the seven tails"

Mizuna looked at his body while feeling the power the chakra of the seven-tailed beast gave him. He closed his first and the air mixed with red chakra around him violently swirled leading the walls and the ground he was standing on to crack

The shinobis near him also got hit by the gust of wind "Stop it, son!" Hiyori shouted at Mizuna

He looked at her and stopped using the red chakra. He then looked at his surroundings only to find the crack on the walls and the ruined furniture.

The clothes of the shinobis are torn and some of them have scratches

Mizuna smiled at them and said "Sorry about that, I got carried away"

The room fell silent
