"So..lemme get this straight..I can transmigrate into the body of any Canon character into the Narutoverse and get thirteen wishes?"
"Yes."
"Okay..I chose Hatake Kakashi. Transmigrate me into his body when he goes home after Minato dies. Erase the original Kakashi's soul but keep his memories intact without any emotional attachment. Along with his knowledge, skills and talents. Make sure the switch is undetectable by anyone, specifically Hatake Sakumo."
"These go without saying. Now, wishes."
"Hmm..first turn Kakashi's Sharingan into the EMS and fully integrate it into his body and bloodline so that he can use it without any backlash and with as much chakra as a single tomoe Sharingan and his descendants inherit permanent three tomoe Sharingan like vision without the need for chakra."
"Steadily increase Kakashi's Chakra reserve until it's equal to the Nibi within a year, Hachibi within ten and also make it part of his bloodline to be passed onto his descendants."
"A stronger and more refined version of the Dead Bone Pulse without any of the associated weaknesses as a bloodline to be passed onto his descendants."
"Extreme affinity for sealing and the inheritance of Uzumaki."
"Healing factor 500 times stronger than than than First Hokage also integrated into the bloodline."
"Get an Otsutsuki from the moon as a wife at the age of twenty one. She'll be born with a Tenseigan and forever in love with me and loyal to me. Let her be extremely attractive and strong. I want to revive an extremely strong Hatake clan with her."
"Well, not bad. I know what you're thinking and Iike it. As a bonus, you'll have lots of children with your wife, all of them identical twins.
Now go and have fun."
