To be honest, the whole battle isn't my favorite, and I find it quite hilarious that there are young adults hired to defend a red-light district wearing suits, no less. However, it tremendously highlights Tsubakino as a character, his idealism, and the way he controls the battle. He truly deserves the Four Kings' moniker. Furthermore, Nii Satoru excels in discussing the complications of poverty through Tsubakino's fight with Suzuri; it gives a bigger perspective on how certain situations are not by choice, but they're forced to experience because of the broken system, compelling a feeling of empathy without excusing his wrongful actions to begin with.
