I cant access it either
Makes me sad. I wish there was a way i could snowplow the game and complete all the sidequests.

Possible Spoilers:
(SPOILER)
As for the 3 Targets, the first 2 times i fought the boss i didnt even kill them i just targeted the CoD the whole time and the last time i fought it i only killed the one that does Lightning because the other one cant be hurt by physical attacks and usually just spams bad breath which has no effect since everyone has ribbon on.


Also dont know if that spoilers but just to be safe.
