"In the yakuza world, the strongest should win. Battles aren't won through things you've born with! So while you and your charismatic buddies ramped around...I kept training in the shadows by myself. Because I believe the strongest always wins."
Masato Aizawa is a minor character who appears during Kiryu's section, and later one of the main antagonists and final boss in Yakuza 5. He is Dojima's bodyguard and Aoyama's secretary alongside his partner and sworn brother Morinaga. In reality he is Kurosawa's son and secretly worked behind the scenes with his father to uproot and conquer the Tojo clan.
Yakuza 5 Edit
Aizawa is mostly quiet and soft spoken towards the beginning, but as the story progresses we see his true self. One example is when he killed his best friend in order to obtain power not to mention training in the shadows for most of his life. Aizawa values power above all else, but does not resort to trickery like his father given the fact he took Saejima and Kiryu on in a fair fight. Aizawa is one of the few chracters throughout the Yakuza series that has some sort of pride given his motives.
Fighting Style Edit
Aizawa relies on brute force. He has several strong strikes and grabs to fight against Kiryu. He is shown to be able to lift Kiryu and even run while carrying Kiryu. Aizawa also seems capable of using a katana but this is never shown in combat.
