At the villagers’ request, we exterminated a one-eyed bear.
As a result, we were unable to stay at the inn we had planned on, and instead took refuge in the settlement of the Forest Folk.
There, I encountered Selene, the Maiden of Death, and the God of Death.
In the course of our conversation, I spoke a little about the Black Dragon, and we conversed about its true name being the Demon Dragon King Vladforen.
I offered Selene a gift, and she and the God of Death took a liking to me.

None of this is a lie. I simply left out certain things.
The part about Selene coming to see me because my soul originates from another world and is therefore rare, the involvement of the Creator God—all of that is completely cut. There is absolutely no way I’m telling Onii-sama that an isekai’d thirty-something is mixed into his little sister!
I also omitted the fact that I already knew the name Vladforen, and that the God of Death merely confirmed that it was indeed the Black Dragon’s true name.
This is not obfustication of truth. It’s just reporting while focusing on the key points.

That she keeps internally justifying herself at every turn is proof that Ekaterina’s sense of guilt is leaking through.

“After that, we continued our journey without incident and arrived at the Mountain Temple. I was able to meet Great-Uncle Isaac, which made me very happy… ah, that is beside the point. Let me return to the main topic. As I reported earlier, an oracle of eruption was delivered at the Mountain Temple. In response to that, Sir Forli and I split up. I hastened home in order to report this to you as quickly as possible, Onii-sama. On the way back, while we had stopped the carriage to let the horses rest, the Black Dragon appeared. It truly was an enormous dragon.”

Ekaterina hesitated for a moment, wondering how best to describe its size. When she said it was about as large as the academy’s small lecture hall with a neck, wings, and a long tail attached, Aleksei’s expression hardened.

“Poor thing. If something like that suddenly appeared, you must have been frightened after all.”
“I was startled at first. But I had already heard about him from the God of Death, so I believed he would not do anything unreasonable.”

Well, what she was told from the God of Death was only that the Black Dragon was the Demon Dragon King Vladforen; her confidence that Vladforen would understand her actually came from her memory from her past life. Still, it did come up in conversation, so it’s true. Details are cut; the report sticks to essentials.
Mina and Oleg would surely remember that I was the one who spoke to the Black Dragon first, so I have to keep my story consistent with theirs while trimming it down.

“When I spoke to him, he changed his form for us. Into that of a human man. Because of that, I was not afraid.”
“Hm… so the tales of the Black Dragon taking human form were true.”
“Yes. He was exceedingly handsome.”

Reducing that peerless beauty to the words “exceedingly handsome” feels almost criminal, but it’s not something language can really capture, so this will have to do.
Perhaps something showed on her face, because Aleksei made a complicated expression.

“To hear you praise a man’s looks like that… this is the first time.”
“But you are the most wonderful of all, Onii-sama! If I never praise other men, it is only because I am always by your side. He truly was beautiful, but even so, to me you are the more wonderful one.”

I’m a brocon, after all!

At Ekaterina’s bright, emphatic declaration, Aleksei looked a little embarrassed.

“In that respect, you are as childish as ever.”
“Oh my, he said something similar as well.”

Given that I’m actually in my thirties inside, that’s a bit of a scam—sorry about that.

“In the first place, he seems to have an acquaintance with the God of Death I mentioned earlier. He heard about me from the god and his wife, and decided he wished to meet me. Since he himself exists within the law of death, he stated clearly that he would not harm someone favored by the spouse of the God of Death. Therefore, there was absolutely no danger to me.”
“I see…”

Aleksei’s expression softened, and Ekaterina felt relieved.
Come to think of it, Grandfather had rather upscale matchmaking tastes, but trying to marry someone off to a Demon Dragon King—now that’s a hyper-fantasy level of matchmaking from the God of Death.

“After that, the two of us spoke pleasantly for a while. I explained things such as reforestation to him. It seems he had taken an interest in what Sir Forli had spoken of.”

The topic of reforestation did come up, and he seemed to remember what Forli had said. Not a single lie told

“He was, as expected, displeased by the felling of forests. He approved of the compromise of maintaining forests through replanting. He stated that he would not be hostile to Jurnova. Nor to the Empire, nor to humanity. Seeing him up close, I understood very well just how powerful a being he is. Might he not rival the army of an entire nation? And he is said to be the king who rules over all magical beasts. To form friendly relations with such an existence would, I believe, be beneficial to Jurnova.”

This is laying the groundwork for what comes next—emphasizing the significance of interacting with the Demon Dragon King. Yes. He is absolutely not someone we want as an enemy.

“…That said, his promise not to be hostile does come with a condition… namely, as long as I am present…”

As the story approached territory likely to trigger brotherly overprotection, Ekaterina’s tone grew hesitant. Aleksei’s eyebrow twitched.

“…It seems he took quite a liking to you.”
“Yes, well… he asked me whether I might consider becoming his companion.”
