Oh, I'm so late to replying to this because work became very hectic, but thank you for permission to make public what I called an essay but which could more accurately be considered a string of consciousness series of observations wrapped like wisteria around the overarching theme that the Port Mafia, even from where it lurks in the shadows, nurtures Chuuya's humanity because it needs him to persist sustainably as one of the pillars of Yokohama's stability.
(I've tried to include some loose semblance of structure and signposting, but the below is largely unedited, so please forgive my inartful articulation and lengthy lead-in. It builds into itself, I hope.)
