Chained Soldier — Season 1
Just as graduation looms and a seemingly unremarkable future stretches before him, Yuuki Wakura’s life takes an extraordinary turn. He's unexpectedly thrust into Mato, a hidden realm teeming with monstrous Shuuki creatures. To defend against this escalating threat, the all-female Demon Defense Force was established – women wielding incredible powers granted by mystical Mato fruits. Yuuki finds himself rescued from a perilous situation by Kyouka Uzen, the formidable leader of the Force’s seventh unit. Though a brilliant warrior, Kyouka's own power, known as "Slave," has always been a frustrating limitation. This ability allows her to control living beings, but past attempts at enslaving Shuuki have yielded only disappointing results. Cornered by an overwhelming swarm, Kyouka makes the desperate decision to use her Slave ability on Yuuki. What follows is astonishing: Yuuki’s enslaved form proves far more potent than anything she's encountered before. Seeing in him a vital key to unlocking her own potential, Kyouka extends an invitation – one that pulls Yuuki into the heart of the Demon Defense Force.
Stepping through a shimmering gate, Yuuki Wakura found himself in a world utterly unlike his own. Before him stood the Demon Defense Force, and at their head was Chief Kyouka Uzen, whose gaze held a promise of reward for any service he migh…
Yuuki accepts a position as a caretaker for the 7th Squadron's dormitory in Mato. Shushu surprises him, and he finds himself unexpectedly made her personal attendant. Just as this arrangement settles, a colossal Shuuki emerges, attacking wi…
Faced with a multitude of Shuuki and a debt demanding repayment, Yuuki and the Demon Defense Force Squadron embark on a journey beyond dimensions.
The Demon Defense Force resolves to address the threat posed by the humanoid Shuuki. Simultaneously, Himari discovers the ability to assume another's power, a power she employs to ensure Yuuki's allegiance.
With a swift "Brand Break," Yuuki disorients Yachiho, sending her reeling back to the moment before the match commenced. Afterward, Himari offers Yuuki a look of appreciation; the time has come for his due reward.
The next contest in the second round will feature Shushu Suruga of the 7th Squadron against Sahara Wakasa of the 6th. Following the match, Shushu has a surprise prepared for Yuuki.
Tenka faced Rairen, and then invoked her power over space. Afterward, Yuuuki began to tidy the room, only to find herself unexpectedly covered in something far more unpleasant than soiled garments.
Tenka desired Yuuki as a companion, a pet of sorts, but Kyouka refused her plea. Nei then spoke of her abilities, of a vision – a promise she had received.
A figure resembling Yuuki's sister materialized, a demon in deceptive guise, and spirited him away. When the disturbance subsided, an adversary attended to Yuuki with a peculiar, clinical interest.
A disquieting reality dawned on Yuuki. Afterward, a truly satisfying recompense awaited him.
Yuuki, bound and helpless, left the fate of the conflict to the girls, who must now channel the power of the peaches in an unrelenting struggle. Just as the battle reaches its peak, figures emerge—those who command the demons themselves.
A renewed purpose ignites within Yuuki: to restore Aoba to her former human self.
