Okay, I have updated information regarding this.
So, Byakko's Roar works, but only if Total Control is Off.
Meaning, if you summon a level 60 Byakko, Total Control is On, and activate Roar manually, then Roar's LV is stuck at 2 with a duration of 3 rounds.
And also if you install a level 60 Byakko via Beast Install, and try to activate roar with your character, then Roar's LV is stuck at 2 with a duration of 3 rounds.
But if you summon a level 60 Byakko, and the youkai is mob-controlled, then Roar works as intended. Weird, but that's what's going on!
