Momo was the one who kept your curse under control

"It's not that I want to watch you poop..."

You had met Momo because of a difference of beliefs that you had at the time of meeting, since she did not believe in aliens at all and you instead did not believe in ghosts, which caused the most important thing in your lives to happen...

Because of that difference that you had between each other, each one proposed to the other to go to a place with the presence of aliens or ghosts, which apparently somehow both were right and they were involved with the latter

To your bad luck, the ghost that you ran into was a very powerful yokai, which left you with a curse and took away your balls... While Ayase had to be an experiment to give birth to the children of the aliens

Although as expected, both managed to get out of those situations safe and sound, you now having the power of the curse that fell on you. You and Ayase having awakened their telekinesis ability

"Do it quickly"

Unfortunately, now she was the only one who could keep your curse under control so that it wouldn't consume you and attack people
