Hoping to see my theory that Ichigo is the next "True Quincy" confirmed.... all his friends BECAME spiritually aware over time and as HE got stronger, none were born that way, even the "fullbring" ones weren't priore to their relationship with Ichigo, and all the other fullbringers were getting attacked by Hollows/ spiritually aware from a much younger age then Chad and Orihime, and Ichigo is a Hybrid "True Quincy" closer to the soul king then Ywatch or Haschwalth so power he gives out may be more like Fullbring powers than Quincy ones... He also started displaying Quincy powers pretty much as soon as two Quincy's he hit with energy attacks ( and thus took in his spiritual power) were killed by other people, these being Ebern and Quilge. As soon as Quilge dies Ichigo began to absorb the Jail almost like he was suddenly able to absorb Reishi like a Quincy.... he couldn't absorb Quilge's reishi the way a normal Quincy would prior to his Quincy powers actually being active, so absorbing the "Jail" CAN'T be what activated them. i think Ichigo and Yhwach probably split Quilge and Eberns power 50/50 since they would have died with both of their spiritual energies in them, and after absorbing one full "Quincys" worth of powers/experience, suddenly Ichigo's use Blut like a pure blood.... like Quilge....
So overpowered, he knows your moves before you do them he can attack you in the future before you can react he can nullify all your abilities, just by seeing them and for the future he likes
