Dridorado Ruins (Hard) has no rules regarding Pacteria, so the rules allow you to gain an advantage by training powerful Pacteria in advance.

However, looking at the running so far, it appears that Pacteria has not been used. Is there an unwritten rule not to bring in Pacteria?

In my opinion, I think it's interesting to utilize the unique element of this game, which is breeding Pacteria.

ex) When I ran with Kozupaku (air 20 x 5 pieces), I ran a time of 16:26, which far exceeded the world record.
