Thank you. I agree this kata is more like 4kyu. But since I am new to creating kata, I acted stupidly and was the first to post the Ruby version, and almost everything is easier in Ruby, especially metaprogramming, so those who evaluated it after solving it in Ruby and rated it easier. Well, besides this, new kata are assessed differently than the old ones, so new ones on the same kyu will often be more difficult, I don’t know exactly why this is so.

Fixed the description and gave a few proof reads
