I've decided to revisit this series and there's something that everyone's missing. Spoilers. Watch it first. The draw of this was that the animation direction was done by none other than Teruaki Murakami of 2007's Taimanin Asagi fame and etc. Basically this was a tug of war of who was gonna get to the bags first. So I'm gonna get straight to the point of what actually was going on. The chick on the cover, Sylvia, actually, almost, was playin everyone the entire time. The main character, Jean, figured something was real funny style throughout but kept it playa. Sylvia more than likely was the oneresponsible for the death of Jean's father (I knew something was up as she didn't show any waterworks whatsoever at the funeral) and directly Jean's grandfather (the owner of the inheritance) death due to their rough sex. Jean was very disappointed when he saw Sylvia and his grandfather going at it but Mireille (purple) remined him to keep it playa, that Sylvia did for both of them. Yeah about that...

Beforehand, Marianne (red) admitted their loss to the inheritance due to Sylvia's on the low relationship with the grandfather. They still got something at the end and all left the mansion.

Lesson here is to always clean up after yourself as ironically that's what would be the trigger for the ending. So someone throughout the series was watching Jean fuck Sylvia and kept leaving cigar remains nearby outside the house. Jean still kept it playa and did some investigating.

It was discovered by Jean at the end that Sylvia was playin him the entire time (in addition to disguising her look to resemble his mother to deceive him and cloud his judgement) by having a very brief conversation with an uninvited, unknown man (while showing the cigars on the table) which then was revealed to be the inheritance lawyer himself (the guy in Episode 1 who "informed" Sylvia and Jean that they was not entitled to the inheritance, a lie obviously as he was manipulating the events along with Sylvia). Sylvia revealed her true bitch voice and they proceeded to
fuck each other hard as Jean looked on outside. Still he kept in playa.

He shed a tear for his deceased predecessors and himself due to the reveal of Sylvia's face. He then proceeded and used the gun, which was already heated up, that his grandfather gave him as a key part of the inheritance and got the drop on both the lawyer and Sylvia. If there's ANY doubt, after the credits it shows Sylvia lying in the, now empty, back house they was staying in, shot and left for dead by Jean.

Street justice.
