I use the Lunar against this boss because he takes a lot more damage when you attack his head and the lunars water moves allow it to go aerial so you can attack his head when it's high.

This is the first Ninja Gaiden music video I made. It's supposed to be a summary of the Ninja Gaiden story. It took awhile to make and I'm happy with the results. The song is called by Mezame, by Yuki Kajiura, from the anime Mai-HiME.
