@BOTMAN Jagaaaaaan is being sincere when he says that, the manga might end like that there's no way of knowing, but that's just the end. I feel like the story that is told before the end is more fulfilling then the end itself, so it wouldn't really matter if Jagaaaaaan died as long as it was justified and he fulfilled his role well in the story.
I have a feeling that this two can become great friends, as their desires are pretty close to being the same, It would be really cool to see them together till the end.
Thank you so much for the chapter, it was great <3<3<3<3<3<3<3<3<3
