姫と騎士 (Princess and Knight)

The stage is "Principality of Italy".

For the next big election, the aristocratic princess will perform "social", "trade" and "audience" of the political affairs to appeal her existence.
The knight who serves her princess uses her limbs to support her in the "workshop," "carriage," and "factory."
The influence of one action will increase the value of the other action.

However, the hearts of the princess and the knight are still passing each other.
When that heart passes again, the princess and the knight will be able to stand in their favor by releasing their hidden powers.
Throughout the Grand Duke, the aristocratic family recognized as the most suitable will be the next Grand Duke.
