[Machine Translation] -I am not a fan of the "secret" of the discipline of respect, but I am a fan of the "secret" of the discipline of respect. Echika stubbornly defends the "secret" of the discipline of respect, and Harold does not want to make her an accomplice. The gap between the two, who avoided dialogue, was deepening. Meanwhile, the possibility surfaces that the mysterious AI "Tosti," which has been continuously deciphered, may have been developed on Farasha Island, a technological research city in Dubai. The city is infiltrated by Ego, an alter ego that reflects the owner's personality, making the investigation extremely difficult due to its unique environment. With the help of Yunus, a boy genius living in the research city, Echika and her team gradually get closer to the truth, but something happens to Biga, who was accompanying them. One year has passed since Echika and Harold met, and their long winter is about to begin again.
