Defeating Berial
Use Grim Grip to reel yourself close to his head, and attack with your sword. Once the combos are done, use Grim Grip while still in the air. When his flames are gone, jump up to his head. Grab his head with the Devil Bringer, then once he lands from that, use Devil Bringer again to throw and punch him. Then, run a short distance away because he will release an explosion around him. Make sure to pick up Green Orbs from the destroyed buildings, and roll to avoid his flame geysers and sword attack. Continue attacking this way, and use your Charge Shot to defeat him in under a minute.

Defeating Demonic Bosses
You can use Nero's Devil Bringer to defeat Demonic Bosses. Before you daze any demonic Boss, get your Devil Trigger as high as possible. As soon as the enemy is dazed, activate Devil Trigger mode, and use the uppercut on them. Using it in different areas of the enemy's body results in a good combo.

Defeating Sparda
Sparda can be knocked down by using Pandora's PF398 Revenge technique. With Pandora equipped, hold X and make two complete circles with the Left Analog-stick, then shoot at Sparda. It may require two shots, but he will fall as though you used the stationary cannon.
