To be honest there isn't much to say about this series. I went into this not knowing what is was about and quickly realised that I made a mistake.
The story begins with two people in a relationship having a bit of a conversation, the dude requests role-play molesting on the train which she agrees to but somehow she gets separated as is raped by some other passengers. The story made no sense and felt worse than it would have been if I had known what I was getting into.
I believe that you might enjoy this if you are in the mood for rape and NTR,
if your not though it will only frustrate you. Some scenes were definitely fap worthy but to me, The rape ruined it.
The art was not to bad although it does depend on preference greatly. The sound was OK although i thought the female voice actress was weak. The best music was at the end during the credits so theres that.
The characters were extremely bland and uninspired so if your the kinda person that wants some depth you porn then look else where.
Overall my enjoyment was a 1, I HATE THIS ANIME! so I will never watch it again but if you like NTR and rape then you may in enjoy this.
