I hated the ACTUAL final boss in the bouncer. I spent all the time going through, maxing all my characters out and then I was expecting to waste the final boss. Nope, not only does he acheive S-Rank max stats, but he also gains another form. I must've spent a total of 10 hours replaying that boss fight before I finally beat him! And the crappy ally AI in the game didn't help either.
