well first of all it would be a suicide for the creators of this incest love story... but they did a great job and kinda remembering similar anime to this entitled "i love my younger sister". well i gave a rating of 8 for the story, and 7 for the art... well the problem in here is the sound... this anime lacks on sound effects and maybe the seiyus didn't put much effort on portraying the character they're dubbing... well as for the characters i gave a rating of 8, enjoynment 7 and overall 8...
