### Summary
The arc ignites in the shadow of Prince Sei Kyou’s noble sacrifice, a tragedy that serves as the final catalyst for the long-simmering war between King Ei Sei and Chancellor Ryo Fui. With the king’s coming of age ceremony looming as the ultimate political deadline, the conflict escalates from covert conspiracy to a desperate, all-or-nothing gambit for the soul of Qin. The battlefield shifts from the frontier to the heart of the capital, as the Queen Dowager’s unholy alliance with Ryo Fui finally bears its venomous fruit. Driven by a twisted maternal rage and manipulated by her lover, Rou Ai, she unleashes her private state of Ai in a full-scale rebellion, aiming to assassinate her own son and install her illegitimate children on the throne. This insurrection is the centerpiece of Ryo Fui’s masterstroke: a coldly calculated plan to let the rebellion burn the capital, only to swoop in as its savior and prove the king’s incompetence once and for all. However, Ei Sei seizes control of the narrative with an audacious counter-move, relocating the ceremony to the capital of Kanyou itself, forcing a direct and bloody confrontation on his own terms. As Rou Ai’s massive, undisciplined army descends upon the city, the defense falls to the few forces available, thrusting the Hi Shin Unit into a familiar, desperate role as the last line of defense for a besieged city. The ensuing battle for Kanyou is a brutal siege fought not on open fields, but in the palace corridors and city streets. While the king rallies the citizens with the same inspiring presence he showed at Sai, the Hi Shin Unit becomes the hardened veteran core of the defense. Xin, now a seasoned commander, leads the charge to protect the royal family, his fight for the future of Qin made deeply personal by the birth of the king’s own child amidst the chaos. The rebellion is ultimately crushed, culminating in a final, chilling confrontation not of swords, but of wills. In the throne room, a triumphant Ei Sei faces a…
