I've already unlocked the fighting app itself (trained with Blood like 4/5 times). It seems like there's a certain trigger that everyone else seems to have hit but I still havent. Thank you for the suport though :)
Have you seen all events with Slate as well? Kind of remember Zorro mentioning that you should get on a good standing with them before that.
Oh I missed that! Thank you :) This was what I was missing
