The Icy hero

'It's over, he's too strong I can't beat him'
These were the things going through Toshiro's head as he lay motionless on the ground ,slowly bleeding to death.
After the last standoff between Ichigo and Aizen, there was a sudden implosion of all spirit energy from all dimensions .
Hollows and shinigami alike were killed by said blast.
Leaving only humans left.
Afterwards pockets of spiritual energy humans called quirks.
Dying just before this implosion Toshiro ,who got caught up in this implosion, for some weird reason became a quirk.
And, oh so coincidentally, entered a boy who looked exactly like himself. And guess what?
His name was Hitsugaya Toshiro.
And his dream is to go to UA high school and become an amazing hero
