*Mirfah: Hm, it appears that Karl was telling the truth.
*Mirfah: Very well then. I shall keep my promise to Karl. I shall tell you what I can.
*Mirfah: This story is from quite some time ago...
*Mirfah: ......
*Mirfah: It begins a short while after I was selected to command the 10th Demon Slayers Squad.
*Mirfah: The 1st through 10th Squads were called to the Summoners' Hall.
*Mirfah: Compared to the other commanders, I was nothing but a nervous infant.
*Mirfah: First there was Owen, the First Summoner who by this time was already legendary...
*Mirfah: As well as Grahdens, his trusted right-hand man, and...
*Mirfah: ...Warlon, their companion who prided himself as being their equal in power.
*Mirfah: And all of the other squad commanders including Griff, of course.
*Mirfah: All of them fiercer monsters than the demons themselves, from my point of view...
*Mirfah: When I was nervous about what was going to happen, Krantz of the 9th Squad had kind words for me...
*Mirfah: Rhoa from the 7th teased me, the Sixth's Kafka cursed...
*Mirfah: The other commanders laughed as they saw this, and...
*Mirfah: ...Griff from the 4th Squad just got mad that everyone was so noisy...
*Mirfah: ......
*Mirfah: They weren't just Summoners. They were people, each with their own charms.
*Mirfah: ......
*Mirfah: We were all ordered by the three leaders of the Summoners' Hall, Owen, Grahdens, and Warlon...
*Mirfah: ...otherwise now known as the Summoners of Old, to investigate Ishgria.
*Mirfah: I was surprised.
*Mirfah: Not only by the fact that demons already existed there long before they were found in Grand Gaia...
*Mirfah: ...but also by the later-stated true purpose of the Summoners' Hall: "Liberation from the gods".
*Mirfah: However, at the same time I was excited.
*Mirfah: The key to "Liberation from the gods" was located here in Ishgria, and...
*Mirfah: ...I was going to be part of the search for it.
*Mirfah: Everyone else had a wide variety of feelings, but...
*Mirfah: ...they all basically agreed to the plan.
*Mirfah: Without realizing the true goal of the Summoners of Old...
 	
*???: What a nostalgic story.
 	
*Mirfah: You... Grahdens...
 	
*Grahdens: We did not have an ulterior "true purpose." Everyone was simply foolish.
 	
*Mirfah: I don't want to hear your excuses.
*Mirfah: You knew the risks of being in Ishgria, and yet you still sent us on a sacrificial recon mission...
*Mirfah: And what's more, you Summoners of Old didn't send reinforcements, just excuses.
 	
*Grahdens: Mirfah, you have to know that...
 	
*Mirfah: I said I don't want to hear it!
*Mirfah: For example, after we departed...
*Mirfah: ...even if there was suddenly a skirmish between the Randall Empire and the Elgaia Federation...
*Mirfah: ...and even if you all got caught up in it, it's still completely inexcusable!
*Mirfah: Everyone except for me died here!
*Mirfah: There is no one left but me!
 	
*Grahdens: ......
 	
*Mirfah: Remember this, Grahdens. I will kill all you Summoners of Old.
*Mirfah: No matter how I have to do it.
 	
*Grahdens: ......
 	
*Grahdens: Mirfah, I did not say it earlier, but allow me to say it now.
*Grahdens: I am truly glad to discover you are alive.
*Grahdens: I am truly thankful that you were able to survive.
 	
*Mirfah: ...... You think that will make me not want to kill you...?
 	
*Grahdens: ......
*Grahdens: .
*Grahdens: I am terribly sorry for getting you all involved in our old battles.
*Grahdens: That's why I ask you to just believe this.
*Grahdens: I, as well as Owen and Warlon...
*Grahdens: ...do not wish for the death of any Summoner who fights for the Summoners' Hall.
*Grahdens: Although I understand that you might find that difficult to believe, since we have sent you on this dangerous mission.
 	
*Grahdens: ......
 	
*Grahdens: Well then, . Shall we be going?
 	
*Grahdens: Where to, you ask?
 	
*Grahdens: Ho ho ho, you haven't changed a bit.
*Grahdens: We are obviously heading to the Weather Tower where the demon of this land is located.
*Grahdens: I believe everyone else should already be on their way there.
 	
*Grahdens: Shall we hurry along now?
*Grahdens: Simply put, if we do not make it there before Owen, we will never hear the end of it.
 	
*Grahdens: ......
*Grahdens: However, what Mirfah said does intrigue me. Why was it after he left that...
