Concept idea:-
reborn into the body of a young boy/girl in the village of Konoha, she/he attends the academy, his/her family is of civilian roots, and so he/she like Sakura has minimal chakra reserves but next to perfect chakra control, being a fan of the series he/she naturally knows all of the tricks on how to train his/her chakra control and exhaust his/her reserves so that they grow larger over time, he/she will use his/her knowledge to become stronger than others, and become a living legend in this world, if Hashirama could do it, why can't he/she.
He/She will become a Sage, a master of his/her own element, and shake the world.
Future ideas:-
Paired with team 7
Water Sage (Healing)
Fire Sage (destruction)
Wind Sage (speed and detection)
Lightning Sage (Speed and power)
Earth Sage (Ultimate defense)
