Does this world have a rift?

"What? Unbelievable, right?" Fellea smiled and said, "He is the one who saved me from my madness and darkness. Thanks to him, I was able to evolve into a Fallen Lusting Angel."

"Ah! Do you know what race Saraya used to be?"

Narita was so surprised that he opened his mouth very wide. Because he was only a skeleton, when he opened his mouth, Fellea could see the bone inside his mouth.

Narita stammered, "What race was Sa...Saraya in the past?"

"Hm… I'm afraid that after I tell you, you won't believe it. Saraya was just a Succubus before."

"What?! Succubus? That lowly and lustful race, that lives on the 'mucus' of men. One of the races with the lowest Tier, on par with Skeletons?"

Fellea said with a bit of a headache: "You don't need to explain so much, it's not that I don't know what kind of race Succubus is."

"Impossible?! How did a Fallen Angel come from a Succubus?! That is a myth!" Narita couldn't seem to believe what Fellea said.
