Synopsis

Despite defeating the Megiddo, the city still hasn't reverted back to normal! Touma promises a worried Ryo Ogami who is missing his son Sora, that he will get him back! Ryo's feelings manifest towards Touma by saying "Do you understand what a parent is feeling?!" Despite this, Touma still promises to keep his word. Feeling frustrated and full of intense emotions, Ryo seeks to inform the sage of what has occurred. The case of the Megiddo is still a mystery, and just where did these people disappear to?!
