Episode 10 of Inu X Boku SS actually had some substance to it. Kagerou is back, and he seems to be interested in spending time with Ririchiyo. He even kidnaps her, and forces her to go to dinner with him. He constantly is spouting semi-funny lines about S&M. He also gave all the characters S&M themed gifts, what does he expect the characters to use them for. Ririchiyo, you better run fast, I don’t even want to think what Kagerou would do to you if you ever married him.
Well Soushi is keeping a big secret, so big that he even got in a fight with Kagerou over it. I bet I know what it is. I am guessing that Soushi is probably the one who was writing to Ririchiyo in the past and not Kagerou. That is probably why Soushi keeps saying he knows Ririchiyo when she had never met him. Also when Soushi asks if she loves Kagerou and she says no he gets angry and says she has been giving mixed signals.
Thanks for reading!!!
