Orochimaru had worked up quite a bit of emotion, wondering whether, after meeting the God of Shinobi, he should reservedly say, "Hello. I've long admired you. It's a pleasure to meet you," or be more worldly and get straight to the business of making a deal.
But in the end, he had overthought it. Objectively speaking, there was only one character's difference between "god" and "crazy." To put it more tactfully, the First Hokage did whatever he pleased, transcended worldly concerns, and fully displayed the bearing of a supreme ruler.
"Monkey is dead too? Who are you? You don't look like a Konoha Ninja."
Although he had noticed Orochimaru long ago, the Second Hokage had kept pretending to devote himself entirely to chatting with his elder brother. Only after Orochimaru spoke did he ask this question... There was no doubt that this third person present was the caster of the Impure World Reincarnation Jutsu.
"I should say that I used to be a Konoha Ninja. I was also the disciple of the Third Hokage. The Third Hokage only died recently." Orochimaru answered the Second Hokage, but most of his attention remained fixed on the First Hokage.
"Has Hiruzen died too...? Could it be that the wars haven't ended yet?" the First Hokage asked.
"The Third Ninja World War ended several years ago. As for the death of my teacher Hiruzen... I was actually responsible for it. We had some ideological conflicts, so I defected from Konoha," Orochimaru said. He was truly being "frank."
"A missing-nin..."
The Second Hokage's gaze immediately turned sharp at those words. Given his usual style, once he learned that this man was a Konoha missing-nin, he should have flown behind Orochimaru and stabbed him in the back the next second. Yet he did not do so
