Michiru Kaiô in her Senshi form is Sailor Neptune. And as her name applies to the god of water she too like Ami has the power to manipulate water. But Neptune is in fact more stronger than Ami (sad to say) She excels better than Ami in swimming. She is the lover of Haruka and she has a knack for playing the violin. Michiru's full name in translation to english would be "Complete Neptune" yeah that makes sense, not!
