To improve physical ability you can train with robin or Terra too. I been notified about the cyborg bug in training field. I will fix it in next update. For now workout with terra or train with robin. and proceed with the waklthrough :)
I see now, I didn't need him to progress to begin with because of the other two. Thank you, and sorry for not trying to think this out myself harder
Cool, man :D
how long do you have to do it? I trained with all 3 for over a week and nothing triggered.
Once is enough. Go to lobby or girls hallway or boys hallway to trigger the event
