Yakuza Kiwami - How To Easily Beat Jo Amon, Secret Boss (Hard Mode)

Equip the Bloody Binding, the Payback Ring, and the Dojima Family Amulet. Then use AppStim RX'es from the drug store to lower your HP to 1. This will MASSIVELY increase your attack power. Use the L2 + R2 attack mode when you have heat to make it even more ridiculous. In the second phase, keep your distance. Amon has impossibly fast moves that do a ton of damage. Be patient and wait for something to easily counter. When he runs in the square pattern, you can Tiger Drop him. When his health is low, use the distance heat move to finish him off. This was done on hard mode. Ez-Pz!
