最新鋭軽巡洋艦姉妹 makes it blatantly obvious that the devs are referring specifically to the Agano sisters.

- 15.2cm Twin Gun Mount is their stock equipment. - Agano & Noshiro refer to themselves as 最新鋭軽巡 and 新鋭阿賀野型軽巡 respectively, highlighting how they were the most advanced light cruiser design by the IJN. Technically there's Ooyodo with a more modern design, but she was the only CL of her class that was finished before the end of the war. - the designs of the other light cruiser classes are way older and therefore don't qualify as "state-of-the-art/cutting-edge/ultramodern/advanced" or however you choose to translate 最新鋭. Whether they have a Kai-2 does not matter.
