I defeated the Red Dragon Knights, the mainstay of the Phallus Kingdom, in Aresta and rose to the rank of Commander of the 8th Legion Legion for my achievements.

　Of course, it's not that I'm not happy, but I think the people around me are more buoyant than the person in question.
　Especially Giron's joy is amazing.
　He praises me with a snorting voice, as he does every day.

''I thought my husband would definitely become a legion leader one day!

　Furthermore, is it because I'm now a legion leader?
　Should I special order a silk robe, like a corps commander's chief of staff?
　He asks.

　The one who comes in for the tea is Lilith the Succubus.

It's true that Ike has risen to the rank of corps commander, but I never said anything about making you his chief of staff. I wonder if you don't think this is a good opportunity to move on.

　He chuckles, "Chuckle".

　Hearing those words, Jiron looks at me with a pale face.
　He had eyes like a puppy that had been abandoned at home.
　I feel sorry for her, so I defend her.

It's Lilith," he said. He can be very useful with this one. I will need you to continue to be my chief of staff.

　Hearing those words, Giron is literally going crazy.
　On the other hand, Lilith on the other hand seems to be worried too, for some reason.
　She looked up and said while looking towards us.

''Ah, Ike-sama, I can continue to accompany you in the newly established Eighth Legion, right?　It's not like I'm the only one going straight to the Seventh Legion, is it?

　Lilith is cerebral and bold, but she also seems to have a certain amount of anxiety.
　He answers that question clearly.

It's a very good idea to be able to have a good idea of what to expect," he said. Everyone will be promoted directly to the Eighth Corps. You will be promoted from unit commander to brigade commander. That's it.

　Upon hearing those words, Lilith said, "Yes! and start dancing with Giron.
　The only person who is calm here is probably the dragon man, Sigan.
　He didn't rejoice in his ascendancy, but calmly questioned me.
　His tone was more like that of a chief of staff than Jiron.

''If the Immortal Brigade will become the Eighth Legion as it is, does that mean that there will be no new recruits?

　I return shortly.

"Not done.
　And--.

　The only person who realized the importance of those words was the dragon man, Shigan.
　Jiron and Lilith are pouting.
　I have no choice, so I'll explain.

''The Immortal Brigade has less than a thousand men right now. That's why we need to form an army.

　Giron finally seemed to realize the gravity of the matter with those words.

'What? Isn't that strange?　Usually an army is made up of at least three thousand of them, right?

　That was correct. Normally, the size of each legion would be at least 3,000, or at most 5,000-6,000.

　A thousand was less than half a legion.

''It's fine. We, the Immortal Brigade, are an invincible brigade. That won't change if we become an army as it is!''

　Lilith declares emphatically, but she's still as cerebral as ever.

　The fact that I became the commander of the corps gives me more discretion than ever before, but it also means that I have more responsibility.
　That's what it means.

　Until now, all I had to do was defend the city of Ivalice to the death and follow Cephiro's instructions, but that's not going to happen anymore.

　Now that I've risen to the rank of legion leader, the cities around Ivalice will come under my control, and I'll have to allocate my troops to them as well.　

　A thousand seems like a lot, but that number also takes into account the humans and dwarves who joined us the other day.

　It's not that I don't trust them, but it would still be premature to leave the control of the city to a non-Demonic brigade leader.

　If I did that, there would inevitably be a backlash from the other demon clans.

　That's also why the Demon King installed me as the commander of his army. He wants to show other demons that coexistence with humans is beneficial by showing them how well he can use humans and sub-humans to his advantage.

　I can't wait to show them that, but don't be in a hurry.
　Whether in a previous life or another world, organizations abhor reform.
　We must produce results as slowly but steadily as possible and show the other corps commanders that we're not alone.

　The best way to do that was to build up our military strength.
　I'll tell everyone about it.
　They all seemed to agree with me in unison.

''In other words, your husband's idea is to leave control of the other cities to the demon brigade commander for the time being, while the troops directly under him will be centered on humans and dwarves, right?

　Giron unusually summed up my intentions.

''That's right. The demon race's strength would be reduced, but at this point, it would be for the best.''

　Or rather, I think that's the only way left.

　The one who was most surprised to hear those words was Lilith. She gets flustered and insists on this.

I'm not going to be able to get it right. I'm not sure if that means that I might end up being the lord of another city?

There might be.

　I returned it as a joke, but Lilith's reaction was more than I could have imagined.

''I'm definitely not willing to do that. If you're going to leave Ike-sama's side, then the position of brigade commander as well. No, I don't even need the position of troop leader. No, I don't even need the rank of brigade commander, I don't even need the rank of troop leader, just a soldier at my side.

　Her expression and tone of voice were serious.
　If I appoint her as my lord, she really has the potential to put her resignation letter on my desk.
　That would be a problem, so I reply in passing.

''Don't worry. It's normal for a second in command to be by the general's side. You're the one who stayed behind at the Ivalice.

　Hearing those words, Lilith pats her chest in relief.

''That's right, it's been decided for a long time that the second-in-command and the commander are a set.

　Giron follows suit.

'We have a set of chiefs of staff too, don't we, mister?

''Yeah,'' I answered, ''but come to think of it, Cephiro didn't keep me on hand when I rose to the position of deputy commander, I remembered again.

　At that time, though, there was probably a reason why I couldn't move the Immortal Brigade from Ivalice, the front line.

　I remembered that, but there was no need to go out of my way to tell them about it and make Lilith worry about it.
　They're all in a congratulatory mood, rejoicing in their rise to prominence.
　I wasn't wild enough to water it down.
