The invisible concept
Kyoya already returned to the Grooma Kingdom.
It was an ascended kingdom, the unique floor where he felt particularly safe. It was also the place where a lot of the strongest people gathered, so he also wanted to have a place for himself here.
Though this particular wish would require a lot of time and no one knew what exactly would happen in the meantime.
Right now, Kyoya knew that the upside down castle was one of the things that worried many people. The unknown movements of other kingdoms caused the Grooma Kingdom's nobles to be especially hasty.
They wanted to find many ways to smoothly overcome the obstacles within this unique place without anyone else getting the benefits out of it, so the pressure from others was immense.
However, Kyoya was also pressured with his own problem.
