Now that we've seen a bit of what happened between Tobio and Renko, he's KINDA sold me on this decision. Living with the person, whose existence reminds me of the worst thing I ever did every single time I look at that person wouldn't be the best to me neither. Still, I think some part of him regrets letting her go.
Isami being happy makes me happy though. He seems to be a nice dad and Koyoi and the kids look happy too. Paisen doesn't look to roughed-up after prison too. I hope they help him find way to live at least.
And fuck Maru.
