Angel Moe becomes Uta no Onee-san! But not only do I sing songs, I also enjoy sex with both my little friends and my big friends! Have fun having sex with the person in the costume who is thinking of retiring, the program producer, and of course the little friends who cooperate with the program! Is this not Uta's sister...Sex's sister...? A world like this is impossible, but if it were, it would be the best sex education TV! The birth of Moe, the angel who can make any worldview into something!
