So the power scaling will be done here along with the basic info of Mc
Our Mc Sae jin is a year old with facial structure of child sung jin woo.
Powers of Mc
1. Chakra capacity of Jubi
2. All elements affinity that includes yin and yang
just to be sure it includes kekkei genkai and kekkei tota elements which will be used by combining the required elements plus yin or yang.For example the wood element will be combination of earth water and yang.The crystal release is the combination of wind earth and yin.
Kekkei tota will be taken as combination of three elements. Yin and yang wouldn't be counted as one of the three elements... For example dust release is the combination of fire wind earth elemental nature..
3.All knowledge of jutsu
4.The og Tenseigan
5.The lightning lightning devil fruit
Now for how strong is Mc let's take a look at the original Mc of "The second coming of gluttony"
According to "vs battle wiki" seol jihu is placed in tier 7A...
7-A: Mountain level
Characters/Weapons who can destroy a mountain, or those who can easily harm characters with mountain level durability
Well seol jihu lies far higher in the list with Spear God ability which is stated to split a continent in half which Makes seol jihu a Tier 6A by the Teir system of vs battle wiki.
Now jihu was able to contend with Parasite queen with spear God which puts her in the same teir 6A.
A God of Heaven ranking 7.5.But she was mentioned to be weakend so we can say she was in Tier high 6A(Multi continental level) when she is in her peak form...
Then Heaven rank 8 or the Creation God could be moon destroying level which is tier 5C by vs battle wiki standards.
The heaven rank 9 is exponentially powerful compared to heaven rank 8 so it could be put in Planetary level which is tier 5B by vs battle wiki standards.
The heaven rank 10 is exponentially powerful compared to heaven rank 9 so it could be put in star level which is tier 4C by vs battle wiki standards.
Not to mention the later two are very rare.
Rare enough that heaven rank 10 was unheard to a God like Parasite queen too....
Seol jihu (Sura gluttony form) is said to as powerful as a heaven rank 8.8
Now for our Mc the the Jubi is placed in tier 5C so our Mc surpasses a normal Creation God just with the help of Jubi level chakra then there are various techniques like lightning cloaking and other stuff like sage mood for natural energy.... Then there is Rikudō Sennin mode which is just a state which along with kuramas cloak puts Naruto in teir 5C.
Then Mc has Tenseigan which Makes toneri a high Kage class able to destroy moon without efforts... Let's take Toneri Ōtsutsuki without Tenseigan equal to Sarutobi Hiruzen who is a Tier High 7A
So Toneri Ōtsutsuki jumps from Tier High 7A to
tier 5C
Not to mention Intangiblity of lightning lightning devil fruit...
So in conclusion Mc has a power level of at least
Heaven rank 9 with different techniques and Outclaases Heaven rank 10 with Tenseigan and Devil fruit ability.... and is more powerful when compared to a Creation God in base form.
