With each fight between youkai, there is the fear of collapse of the small land of Gensokyo.

However, if youkai are unable to fight, their power will gradually vanish.

Therefore, I propose the following contract for the allowance for duels.

That youkai can easily cause disasters.

That humans can easily resolve disasters.

That use of one's full abilities is to be denied.

That there are no things superior to beauty and thought.

- Each spell shall be given a beautiful and meaningful name.

- The number of named spells to be used shall be announced beforehand.

  Attacks relying on physical strength are not to be repeated.

- Do not attack without reason.

  Reason becomes its own power.

- If all your named spells are defeated, you are defeated, regardless of your remaining strength.

  If victorious against a human, you may not kill them.

- The name of the spell shall be recorded on paper in the same form as this contract.

  As a result, all of the aforementioned regulations become absolute.

This paper will be called the "spell card".

A concrete method of dueling may be discussed later with the shrine maiden.

Draft of the Spell Card Rules.

Although the shrine maiden decided on these rules,

the original draft is written on the same paper as the youkai's contract.

Did a youkai propose these rules to the shrine maiden?

I wonder who could have written them.
