Chained Soldier 2

Having overcome a fierce battle, Yuuki continues to fulfill his duties as a caretaker while showing steady growth. Meanwhile, by the order of Ren Yamashiro, the Supreme Commander, Yuuki is invited to attend the Commanders' Assembly alongside Kyouka. Overwhelmed by the commanding presence of the squad commanders, Yuuki manages to finish his greetings.

On the night of the Commanders' Assembly, an intrusion by one of the Eight Thunder Gods into Yuuki's room puts the 7th Squad on high alert. Yuuki sets out to survey the area together with Nei, taking on the Eternal Chains: Slave, Shining Star form. However, the entire process of Lending power is witnessed by Ren Yamashiro, the Supreme Commander herself.

Through joint training between the 5th, 6th, and 7th Squads, each member steadily strengthens their abilities. Amid this, Yakumo Ezo, commander of the 5th Squad, requests to borrow Yuuki. Seeing Yuuki's potential as a new combat asset, Kyouka reluctantly agrees to lend him out.

The 7th Squad heads to the Defense Demon Force HQ for joint training with the 10th Squad. Summoned by the Supreme Commander Ren Yamashiro, Kyouka and Yuuki go to meet her alone. Her purpose is to borrow Yuuki. The moment Ren touches the chain, Yuuki responds to her overwhelming power and transforms into a new form, Killer Fang, taking on a grotesque, ominous appearance.

The ritual known as the Azuma Banquet is held to decide the next head of the Azumas. Accompanied by Yuuki and the others, Himari and Yachiho step into the venue. Within the tense gathering of the entire Azuma clan, Himari is confronted by Homare, who once bullied her. Refusing to back down, Himari boldly declares to crush her. With Yuuki, she charges toward a battle that will decide their fate.

After participating in the Azuma Banquet and defeating Homare, Yuuki and Himari come face to face with Fubuki, commander of the 9th Squad. Though they fight using the evolved Slave form, "Skyward," Yuuki shields Himari from Fubuki's overwhelming strike and loses consciousness. Left on her own, Himari challenges her mother using only her own power.
