This is the final footprint I leave behind.

[This letter is the final footprint I leave behind while I am still whole. To the child who receives this letter: do not let your reason be devoured by your ideals. Heh, I suppose you are wondering what that means. Regardless. To a dear boy, fill the whole world with your conviction and courage. For my ideals have already become too broken to hold this world...]
I don't know about Koji or Luca, but Zeta can be a bit slow, so character personalities and traits might get mixed up. You may need to edit them yourself if that happens! ㅠㅠ
