Akane-Iro ni Somaru Saka(2008)

Junichi Nagase was a real delinquent in middle school, one nasty enough that he earned the nickame Geno Killer, and its by this less than flattering epithet that Yuuhi Katagiri first comes to know him when he rescues her from two thugs one evening. Needless to say, both are stunned when not only does Yuuhi find herself transferred into the same high school class as the Killer, but that shock grows into outright stupefaction when Yuuhi shows up at Junichis house with the mind-blowing announcement that shes supposed to move in with him! It seems that theyre engaged, and since this is the first that Junichi and his younger sister Minato have first heard of the arranged marriage set up by their parents, its an idea thats going to take a little getting used to. Get ready for ties that bind and gag as bad boy and good girl collide cohabitationally while the entire school gets to watch!
