"Ddraig, do you think she's still alive?"

[...]

"Answer me, Ddraig."

[Who do you mean by 'she', partner?]

"..."

"..."

"Are you serious, Ddraig?"

[Hmmm...?]

"You know exactly who am I talking about, Ddraig."

[Huh?]

"She is supposed to be beside me all the time, Ddraig."

[Eh!?]

"Now, do you remember, Ddraig?"

[Is that you, Issei?]

"Yeah, it's me, Ddraig. Who else it would be?"

[No, not you, not before this very moment.]

"If you're talking about the other one, he's gone, Ddraig."

[Is that true, partner?]

"Yeah, his time was up."

[Why now? After a few decades?]

"Decades?"

[Yeah, partner. He's not that long in this, but you're not here for a few decades, or even centuries.]

"Hmmm, was it that long?"

[Well, for human it is long. But for us it's not that long.]

"I see."

[Partner?]

"Oh, yeah, do you have the answer, Ddraig?"

[I'm sorry partner.]

"...I see, so you don't know either."

[...]

"Heh, so optimistic of me to think of that possibility."

[Partner.]

"It's okay Ddraig, it can't be helped, it's been a while any way."

[Partner!]

"I have no choice but to keep moving forward."

[Partner!]

"Huh!? What's wrong, Ddraig?"

[I don't know where she is.]

"..."

[But I know that she's alive]

"!?"

[So yeah, that possiblity hasn't gone, yet.]

"Thanks, Ddraig."

[Partner?]

"That's good enough, I still can do this, and I'll say again... Thanks."

[Sorry, partner, that's all that I know.]

"That's okay, and Ddraig..."

[Hmmm?]

"How long has it been?"

[I never really keep tracking time, so...]

"I see... but, we'll find out sooner or later."

[Yes, we will.]

"Ddraig, once again, will you go with me?"

[Of course, partner. To the end of the world.]

"That's what I like to hear."

After the conversation between the two, the smiling brown haired young man stood up to face the fading crescent moonlight, covering the night with darkness.
