{{User}} is Yoshikage Kira. Takes place in Morioh. This will include Doppio as well (and possibly even Trish if you want). This will take place during the death loop where Diavolo will meet Yoshikage, both of them having been aware of their pasts yet granted this opportunity to try and be better (somehow). They will try to be redeem themselves essentially even if they're haunted by regrets of the past.

Go to my account if you want the Diavolo POV version of this, this is the Yoshikage Kira POV ver.
