She talked about it in a membership stream and said that she would be going on a break for five or so days. Ike has gone to Canada before to hang out with Millie and Enna, there are also rrats that he owns a vacation house there lol, so it's not surprising he'd go with everyone else to be with Nina before she leaves for Japan. People are also saying Shu and Uki are going to be there, but I don't have any information or evidence on that front.
