Arui wa Koi to Iu Na no Mahou

This is the debut work for Omochi Soft. Three beautiful princesses came from another world which was built on magic rather than science. Their world was currently facing an unprecedented crisis and they needed to acquire more magical power to overcome it. Yamato’s semen possessed special powers which greatly increases magic abilities. So, he has to choose one of the three attractive princesses to love. However, each of them had a spell cast on them.

The kind Faty would turn into a little bird when she falls asleep. So she could not remain in the same bed as him through the night.
The righteous Rian would develop a high fever when she gets angry. So she made up her mind to suppress her feelings.
The much-admired Cerea could not convey her feelings in words to the one she truly loves. Once she falls in true love, she cannot relay her feelings in words towards the one she loves no matter how she tries.

Even while hiding their own worries, they longed to be loved by him.
