How Should I Be a Ninja as a Substitute?

My name is Kujo Senhiro, I am a 12-year-old stand-in ninja. Live in a two-story cabin in the southern part of Konoha Village. I go to school at a ninja school and am about to graduate. I go home at 8pm every night. I don't smoke. I only drink a little bit. I go to bed at 11pm. I have to sleep for 9 hours a day. Before going to bed, I must drink a glass of warm water, then do JOJO for 30 minutes, go to bed, fall asleep immediately, and sleep until dawn. I will never leave fatigue and stress until the next day. My classmates all said I was normal. This novel and its characters are purely fictitious.
