I'm not sure if there's a yaziro ending, the modded version has one though. There isn't any way to upgrade him to lv5 organically yet, use event tester to see lv 5 event options. I don't recommend changing his relationship level to 5 with mtool or something since it disables his combat events altogether.How do i get the Yaziro's bad ending ? Is there even one ? Can i get his relationship to 5+
