その頃、ノーザンベースの尾上と大秦寺があの剣士によって急襲されていた。
Touma goes on yet another rampage as Primitive Dragon. However, Rintaro had his Wonder Ride Books stolen by Primitive Dragon, so it was Saikou and Calibur who were the unlikely ones to save Mei's life in the nick of time. Touma suffers a dreadful nightmare that he will unknowingly kill his friends in the midst of another mindless rampage as Primitive Dragon. He's concerned that if he doesn't do something about this now, he will be fighting his own friends more than the Megid and the traitor in the Sword of Logos. Meanwhile, Rintaro has an audience with Master Logos where he is reminded of just how dangerous Touma is right now. It isn't long before Mei reaches out to Rintaro to meet with her and Touma. It's been a long time since they've seen each other again.. It was just then that Ryo and Tetsuo were suddenly attacked by a new swordsman within the Northern Base.
