It was finally time to tell it. He could have been blunt, played around with the idea to make it sound like a joke at first, but ultimately he went on to address it all: "What I'm about to tell you is harmless to us if only you are allowed to know. I could dwell deeper into the subject, but I did my homework, so to say, and the less people to be in the know, the better."
Kiroku agreed with a nod without averting his gaze. "Alright... The truth is about Tsubasa Yakou, your nephew. People told stories of his ghost haunting the last game he was playing, and suddenly... The "ghost in the machine" was gone, people handwaved it as a programmers mischief.", the way Kabano was phrasing was intended to bring things from past to present.
"The truth behind "Neon Moth's Ghost" is that Yakou's consciousness was stuck in the machine, and effectively became a ghost. But this isn't your average spooky ghost story, oh, no... In truth, he denied that he was dead, he claimed to be very much alive, and no AI could replicate that behavior to a T. Then, one day, the server he was on was removed and taken far away to keep the paranormal phenomenon a secret from what we call "Narrow Reality"... Are you with me here?", and to Kabano's question, Kiroku could only mumble "My nephew is a ghost?! But... Go on."
"In that place, his ghost was alone in a server that was maintained active, possibly for contact and study, or who knows... He could be given a robot body of some sort. But what happened was the birth of a modern yokai. And that Yokai is me: Cyber Kitsune Neon Moth.", as he said that, he let his true nature show just slightly, startling Kiroku, who stumbled in his chair, but then learned forth and reached at the projection of ears above Neon's head. "Oh, by the Gods, it's real! Wait, you telling me you are Yakou! How about you prove me then?!", Kiroku rapidly withdrew his hands, crossing his arms in a stern expression.
As Neon returned to his Kabano disguise, he gave a hearty laughter and went "Come now, Uncle... I know your all-time favorite game is Dragon Quest, you hide a Famicom under the floorboards in your room, your gameplay time with Dragon Quest 4 exceeds 73 hours but still falls short of 74 hours, Yakou once accidentally erased your Dragon Quest 3 save but you simply played it with him on the Game Boy Color for many hours, and the saké you drink on the day we lost my parents is a Tozai, with a hint of strawberry. I also noticed you had a Tozai stashed in the cupboard, hope you don't play on drinking it alone tonight.."
Kiroku's mouth went agape, absolutely flabbergasted. A smug Kabano and a surprised Kiroku, face to face, until Kiroku grabbed him by the shoulders and finally acknowledged "Yakou, that is really you! But to come back to life like that... All this time I... I really wanted to tell you how much I regret telling you such mean things, all I really wanted was you to stop eating junk food and start to live your life!", he hugged Kabano tightly, who also held him close. It was clear the good Uncle had just opened his waterworks.
"At last, I'm home...", Kabano finally shed a few tears he had been holding for long.
