He was waiting for her

"I was waiting for you," Mineta said. "So we could harem hunt together!"

"Oooh!" Midnight giggled. "Sexy." she gave him a kiss on the cheek.

Mineta and Midnight, hands clasped together, made their way down the hall until they saw Momo and Mina chatting.

Mineta wrote in his book.

"Momo is now a Pleasure-Bot that is based off Momo Yaoyorozu, that can be programmed by me and Midnight as we see fit."

And

"Mina is now me and Midnight's sexy pet cat in heat."

Mineta knew that with the notebook, these changes wouldn't be permanent. Well, maybe they would, but Mineta was sure he wouldn't like Mina as a cat or Momo as a sexbot forever.

He watched as the changes overcame the girls.
