These are two characters that I did in a manga series that I gave up on. Chichi is the one on the left and Taiyuu is on the right. Taiyuu also appearce in Yubashiri (a major cross over of all my series I had thought of or was doing two years ago, including Miyo and Kiki and Lele).
The two are orphans who grow up in the care of a monk and learn ninjatsu along with Tsuki (a brooding and cold boy) and their master Zaha.
Comments would be nice, please!
