Not again :x
I really didn't expect it to happen - Nitta Youka plagiarising - out-and-out tracing - poses, clothes and scenes from fashion magazines (proof here might be NWS). Manga artists often use photos for reference, but not quite this blatantly.

The last time something like this happened, Suetsugu Yuki was accused of plagiarising several poses from the popular manga Slam Dunk. (Someone on 2ch discovered it. The internet does wonders.) The publisher of Suetsugu's work issued an apology, and ceased printing all of her work.

Nitta Youka's more popular than Suetsugu was, and the manga in question has been animated - pulling the plug won't be easy :x

(As an aside: Even with manga, Western fandom is usually pretty OMG stop being so hard on my favourite writer for plagiarising!! It doesn't matter if s/he did a little something bad. This is true even of other people like entertainers and their indiscriminaces. But Japanese fandom's always like: you did something WRONG, we will NEVER forgive you. The NewS underage drinking incident is a recent example.

The Chinese are like that too, I think. Everyone hates Zhang Ziyi and Gong Li for being "women who bring shame on the Chinese", "act completely like Westerners", "wear revealing clothing", "using their fame to get (Western) boyfriends", and "having multiple boyfriends". - There's another word for that last one, but let's not go there.)
