I can understand about wanting to avoid embarrassing past but considering how “devoted” his apprentice is, him sending the message “don’t look for me” will be interpreted by her as “you are not worthy to see me yet so do better.” Thus she will likely be more aggressive with expanding the guild. I wonder how she compares in strength to other climbers (she should be among the strongest S rank but how does that compare to climbers and MC)?
Also, I wonder what the story is about the “true tower“ (the one where earth is apparently the 9th floor)? What I mean by that is who are the beings climbing it? Why are they climbing it (is there a reward and if so what?)? Do they even have a choice? Lore behind it is interesting to find out
