"My sister has been sold! What should I do Yuuta-sama?"
"The answer is obvious. Help me fuck your sister."

Wow, this is a 100% better than the LN, the characters have no depth in the novel and the illustrations looked similar, even parthenos was not that tall, and her sister didn’t use glasses and the MC never used the prophecy skill after getting it, maybe this is the WN adaptation but I don’t think there is a WN, idk man
