I don't understand. If Orochimaru could so easily get his arms back by just wearing the Shinigami mask and cutting the Shinigami's stomach then why didn't he do it before? Why didn't he get his arms back by cutting the Shinigami's stomach before? He instead went after Tsunade to heal his arms...
Did Orochomaru require Zetus to get his arms back or was he just plain stupid and had forgotten about the Shinigami mask?
