Reading this and seeing just how much she's even helping Kuro...
I personally would like to see this ending with her taking up the same role / task as Kuro, and becoming his second. or aide. or "helper" or whatever the term would be.
I feel like she'd be uniquely qualified (or at least one of the very potently capable) Reapers for those Newly-Dead, in helping them resolve their own regrets. The fact she could do something so substantial for Kyouko, even if she didn't "save" her in time, means that with more left on the clock...she probably could have succeeded.
She's got 2 of her 3 to go, still, and very few chapters to do it. So if I could wish for my own Happy(ish) Ending for Hotaru, it would be finding a way to assist others as someone/thing like Kuro. She's always been that sort of person to begin with--but being able to do so with newfound agency, with a healthier and more self-aware mindset...preventing more Souls from becoming lost in the human world? Feels like a calling, if anything.
I really am apprehensive about her facing her Final Regret still, but here's to as much catharsis for Haruto as possible.
Thanks for the TL work as always. Thinking on it more...I'm glad this is a shorter-run series, because I somewhat fear it could become gut wrenching, allowing events like this chapter to play out over longer spans of time, sitting in these feelings and with these thoughts for so much longer.
Sometimes brevity is a blessing, I suppose.
