In a flashback, Sylpha tests her sword on pressed straw mats, but they quickly wear out and cannot withstand her powerful slashes.

In the present, Ren identifies the second prince, while Crow recognizes a familiar maid. Sylpha interrogates the guild members about Prince Lloyd's whereabouts, threatening to behead them if they remain silent or lie. Under pressure, they reveal that Lloyd is fighting the Demon Lord at the prince's castle.

Albert is skeptical of Lloyd's alleged involvement with the guild and suspects a trick. Ren tries to build trust, explaining that Lloyd is fighting to rescue Jade, a captured family member.

Suddenly, the bridge collapses, and demons approach the riverbank, forcing Albert to retreat. Sylpha remains determined to find Lloyd and rides with Shiro toward him despite the great distance. Polka, an eighth-class demon, appears and boasts of his swordsmanship.

Babylon joins Albert in fighting the demons and reveals that the citizens of Lordost have been taken over by demons and cannot be saved. Albert summons powerful flames to combat the invaders, resolved to free the citizens' bodies from demonic control.

Polka demonstrates his mastery of the Demon Blade style and the Lordost school of swordsmanship. Sylpha responds with her own techniques, matching his skill. Polka mocks the value of humanity, while Sylpha wields her new sword, gifted by Lloyd and Dian.

Sylpha names her sword "Demonbane," a sign of its purpose to slay demons. Polka unleashes his ultimate secret technique, confident in his superiority. Sylpha counters with her House Langlis techniques, ready to end the demonic threat.

At the end of the episode, Guisarme comments on the ongoing battle and hints that more magic awaits in the next episode, titled "Jade's Last Words."
