Rukia gives Ichigo power
Ichigo has a sword in Quazi Shikai mode -- I'm not counting it as full Shikai since it wasn't his to begin with.
Ichigo loses power then reclaims his real sword in Shikai mode
the old man tells him his name & then Ichigo releases all hell in that pit.
His sword wasn`t released the first time around, it was just big because he has a high reiatsu and couldn`t supress it.
