I can't believe there wasn't a single pic of A-RISE up yet. But I'm having difficulty deciding on the romanization of the name of the girl on the right, 統堂英玲奈. Various sites appear to be split fairly evenly between Erina (e.g. ANN) and Erena (e.g. Wikipedia), and the official site doesn't even mention her. Reading the kanji would seem to favor Erena, but I'm not sure.
