Kodama (the one on the left) was the first "Ninja Master" to be created by Mahler. She used to be a mouse, and was sent to Keiichi's house to kill everyone, but when Belldandy stopped her, she decided to serve Belldandy. She is the strongest of the three Ninja Masters, she can duplicate her body (She can split herself up more times than Urd can), and is good at illusions and disguises.

Hikari (the one in the middle) was the second Ninja Master to be created. She and Kodama used to be very close friends when they were mice. She was sent to the temple to kill Kodama, because she disobeyed Mahler's orders, but in the end, she decides to stay with Kodama. Hikari is the fastest of the three, and can split herself just like Kodama.

Nojomi (hmmm, I wonder which one's left, the one on the right of course!) is the third ninja master. She just appeared in four pannels in the Manga volume 53 to call all the other ninjas that were hiding in the various places of the temple Keiichi lives in, so not much information is found about her. In the end of the chapter, she and all the other ninjas gave up working for Mahler.
