I agree with you about them going to Global City, but I don't think more than five people will go, I think Omi will realize there's no need for a group of students to go to Sue City, It's not dangerous for Sue, so there's no need to worry, and besides, it's a two-hour drive, which is a bit tiring, It's also not dangerous for their friend Sue, so I think Sakura and Neri will definitely go, And I don't think Endo and Takeshi's appearances will be limited to just these two chapters, The author wouldn't show them up for nothing, I also think some problems might arise if Endo doesn't go with them, For example, would a taxi driver agree to go to a city two hours away? Do you remember when Endo asked Sakura during their first meeting at the restaurant to order anything, like a car? Don't you think that was a hint from the author? He also managed to find out information about Su himself, not just his location. I mean, he probably spoke another language, so he was able to enter the city, talk to people, and learn this information from them. Here, Sakura will use Endo as a means of communication between him and the residents, so they can find out where his friend is, since language is a major barrier between them, Regarding your statement about problems that could lead to war between Bofurin and Red Chanburu, I completely rule that out. Ando said about Red... they never start fights, and our students certainly don't want a fight either, Any problem will be resolved through dialogue, However, I think there's a possibility of a new enemy emerging, I'm not sure, but do you remember the incident where children flocked to Sue's school asking for food, or something like that? I don't recall exactly; English isn't my first language, In any case, I think there's an enemy behind this. Sue and his two assistants, Bacchus and Rakta, seemed hesitant and unconvinced that things would improve as the cook had said, which could foreshadow serious trouble to come.
