飛羽真が手にした新たな聖剣の力により、マスターロゴスが生み出した本は全て無くなり、消えていた街も元に戻った。マスターロゴスを一旦退けたが、柛代兄妹、蓮、そして賢人は飛羽真たちの輪に加わることはなかった。
一方、マスターロゴスは飛羽真が生み出した伝説の聖剣と、ルナの出現を感じ、全てを手にするべく動き出す。飛羽真を中心に剣士たちの思いで生まれた聖剣は、マスターロゴスの思惑通りなのか。そして、飛羽真は改めてマスターロゴスと話がしたいと皆に告げる。そんな中、凌牙と玲花、そして賢人は自らの意志である行動をとる。
With the power of the new Seiken that Touma has acquired, all the books created by Master Logos have disappeared, and the sections of the vanished cities have also been restored. Although they all opposed Master Logos however, the Shindai siblings, Ren, and Kento still haven't chosen to side with Touma and the others. On the other hand, Master Logos senses the power derived from that mythical Seiken created by Touma and Luna, and continues to advance his plan more rapidly. Was the creation of this Seiken forged from the emotions of the swordsmen tied to Touma exactly what Master Logos wanted? Not to mention that Touma wants to speak with Master Logos once again. Meanwhile, Ryouga, Reika, and Kento start to make paths of their own.
