The sudden system notification filled Uchiha Sora with delight.
The system had been pretty reliable lately. He never expected to awaken Tsukuyomi, the Genjutsu-type Dōjutsu possessed by Uchiha Itachi!

He needed Yakushi Nonō's absolute loyalty.
Uchiha Sora said, "I appoint you head of the Intelligence Department. Starting today, begin building an intelligence network. I'll give you the broadest authority possible, so go ahead and do
