WARNING:
THIS IS NOT CONSISTENT IN THE SLIGHTEST

I nearly lost my ticket here. This run was done with 7 minutes left. Your degree of execution doesn't matter, I think, just whether or not Neru crits enough. It's a difference of like 10 or 20 bars of HP that Neru may or may not due along the way.

My UNeru has level 17 bonus attack, and I have all 3 Nerus at 39 affection, IDK if the affection bonus is reflected on the stats sheet, but it says she has 8421 attack
