The main plot points are there, but Takuto's backstory is different, which throws it off a bit, and the ending is WAY different, but I don't want to spoil anything for you. :3
This is odd. Did Takuto just kill a person? He hit this guys nose upward real hard and he fell to the ground. ( And I know that that is supposed to kill )
It explains Mitsuki's situation, where Takuto and Meroko come from and why they're here, and what Fuzuki and Wakaouji have the hell to do with it all. :D
