Concept idea:-
Reborn into the Naruto universe as a newborn babe, he discovers his abysmal chakra reserves soon after and in an attempt to enlarge his reserves begins circulating his chakra through his body, but at such a young age his chakra reserves are mostly made of Yang chakra.
As a result of Yang chakra circulating his body from a young age he begins to develop much faster and grow much larger than regular people.
By the time he is 12 he already is standing at the height of 13 feet, and by the time he is 16 is is already 17 feet tall, and by 18 years old he caps out at 20'4 inches tall.
As a result he seeks out the Akimichi clan to ask for their help to use jutsu to reduce his height to half of what he is.
12yo= 6'5/13'0
16yo= 8'5/17'0
18yo= 10'2/20'4
Future ideas:-
During his younger years he begins to meditate on nature chakra with a unique double affinity for wind and water, forming a path to ice nature chakra to make him a Giant Ice Sage.
