I Summon the Zanpakutō in the Ninja World

Gu Mingyue, the eldest princess of Skylark Kingdom, one day on a whim saved a little eunuch who was beaten and dying. In order to repay the favor, the little eunuch stayed by her side to serve the eldest princess. She thought she was a well-behaved and obedient janitor, but she didn't expect that she turned out to be a wolf in sheep's clothing... ———— "You can only be a janitor by my side. Are you still willing?" "Yes." As long as I'm by His Highness's side, what does it matter if I'm just an idiot? This novel and its characters are purely fictitious.
