Have you guys notice that the "Sensui Seven" share similarities in numbers. As such, "Sensui Seven", Sensui's seven personalities and the "Seven Deadliest Sins". Ironic isn't it? They all share the same number and the members share the each of the sins.
Kamiya - Wrath Makihara - Gluttony Hagiri - Pride Mitarai - Envy Amanuma - Sloth Itsuki - Lust Elder Toguro - Greed
But the true Sensui is devoid of any true sin, like a fallen angel.
