The name of this C75 manga/book/doujin is Injoku Marina and this is very likely an original character since there are a few other OCs there (although it IS a Gundam 00 manga with Marina Ismail)
Marina Ismail is in full katakana (γγͺγγ»γ€γΉγγ€γΌγ«) and this is indeed different from both her official appearance and the way this artist draws her.
