Damn I knew Ranzou’s butler is a creep too but not this much. He is just like Norihiko but with more self-restraint. I never understood why ppl would ship him with Ranzou. As long as Ikurou, Sachiko, and Ranzou gets an happy ending, I am happy. The rest (minus the college friend) can all burn and die.
i have vols.1-4 irl and what i understood in vol.4 is:
Sachiko (Ikuro's wife) decides to hang out more with Ranzou, (i dunno why) and Ranzou's personal butler gets jealous and attempts to kidnap her / murder her. Sachiko eventually finds out and forgives him, Ikuro and Norihiko grew distant because of what happened in volume 3 (where Ikuro got raped). He even threw a plate at Norihiko's right eye, hence he wears an eyepatch for the entire book.
Later on in volume 4, Norihiko and Ranzou's butler talk about something at the shack-like place and Ikuro eavesdrop to hear what they are talking about, Norihiko catches him and tells Ranzou's butler that he can do whatever he pleases with Ikuro. And yes, Ikuro gets raped by Ranzou's butler.
After that, Ikuro plans to burn the whole mansion down so he made everyone leave. He even made Sachiko sign the divorce papers, which his wife refuses to do so. Norihiko visits Ikuro and they both do it, and the fire starts. Ranzou runs back to the mansion and saves only Ikuro, not Norihiko. (He dashed away very quickly). There's one panel where Norihiko gets engulfed by the flames.
Ikuro and Ranzou are discovered by Ikuro's old college friend, and that's it for the meantime.
