Is there any reason to max out on BP (Battle Points)

[Ryofu]

Is there any specific reasons to do so?

Re-running for more AP is the most I can comprehend you'd get more for, aside from quests asking for max BP.

Yes, there's a reason.

If you read the description for Battle Points, it goes:


Indicated the level of completion for the Battle.
If your Completion Points reach a certain number or,
if you have a certain number of Battles in which you
achieved a perfect Achievement Rate,
you may receive a special item or title.

A completion-ist's reward~

What my OCD gets to pay off, YES!
