After coming back from the picnic, I didn't head off once more.
It was simply because the places that the two other Spirit Kings were in weren't in the Kite Kingdom.
They were in other countries, which made it hard for me to go find them without attracting any attention.
Right now, I was quite the famous person and anything that I did would attract attention from other people. So it was hard for me to move around without causing a commotion.
The moment that a commotion was caused, it would be even harder for me to sneak into the dungeon that I wanted to go to.
If I were to trigger the contract with the Spirit King, then there would be even more signs that something was happening.
It was only different since it was Undine that I had contracted.
Since she was the Water Spirit King, that meant that the signs were all under the lake and didn't show themselves to others. That was how I had been able to hide the fact that I had made the contract with Undine.
