I don’t mind the trap character as a child even though you timeskipped most of it. Anyhow I thought since you made him live in an orphanage near midoriyas house he was going to go to school with him and bakugo but then I believe you made him move in with grand Torimo (I’m not sure since you TIMESKIPPED everything) anyhow did he even go to school because you made no mention of it at all.
Haki is an amazing choice. The Sharingan is dependent on an organ while haki is mostly Will. Therefore if he were to say lose his eyes he doesn't lose his abilities. Personally the bear abilities are those that stay with the character no matter what happens. My frustration with bleach powers is just that. It doesn't make sense for zanpaktos to function the way they do. Manifesting willpower and attacking with it. What if their zanpaktos break? Doesn't that mean their willpower has shattered? Extreme damage to soul force? While that anime has some of my favorite superpowers, it seems incredibly illogical. Anyways, haki, energy manipulation, cultivating mind palaces or improving memory slash intelligence would be my priorities when offered a chance like this. The only fanboy moment was choosing the unlimited blade works. Which is extremely powerful and popular as an ability. Personally I'd like to see him do might guys training a bit. While the weights aren't that good, might guy is a beast of Taijutsu. His training would definitely help!
I would have gone for senbonzakura because it is a sword, so it would go so well with unlimited blade works, plus it would have been much easier to explain. That plus the fact it is so versatile. I mean you are controlling tiny blades that look like sakura tree petals. Just imagine Gaara with his sand, or even just watch the fight between bankai Ichigo and byakuya kuchiki. It would be perfect crowd control, plus long range.
one thing I don't like the order of power of the abilities at all, better you would have left it as the 4 basic power scale common, rare, legendary, mythical and deity since most of that is not You are going to use it and if the ability is close to one of them you just round it up and that's it and I didn't like that in the statistics either Mentions that he has an ultra rare body or something like that since rei only has a normal body he is just an ordinary human and what you gave me to understand is that he was much stronger than all might alone Only because of the rareness of the body, and if you leave it on the same path it will be a headache to measure the strength of the villains in the future example if you continue like this, you will classify all for One as a deity Or you can also put it as very weak
