YMMV / Lupin III: Blood Seal ~Eternal Mermaid~

• Complete Monster: Himuro, a vile Arms Dealer who uses medical technology company as a front for his dealings, seeks the blood of his immortal ancestor Yaobikuni for his own ends. After introducing himself by murdering a rival crime lord and all of his men with a smirk on his face, Himuro is later revealed to be sadistically experimenting on dozens of innocent people to figure out the secret behind Yaobikuni's immortality, at one point shooting one of his victims to see if they've become immortal and remaining indifferent when they don't resurrect. Himuro uses a 14-year-old girl as a Human Shield; tortures and abuses his fellow immortal descendant Mika; throws his own mooks to die in death traps; and ultimately wants to throw the entire world into war and kill as many people as he can with immortal Super Soldiers.
