The ability is overpowered, sorry to say. The Death Note universe functions under the reality where you can kill anyone by writing a name in a notebook, which is fine there, since it's a universe filled only with normal humans and it's really meant to be a murder mystery/intrigue type of anime (and very well done, might I add). When you apply that same idea to the Bleach universe, all hell breaks loose. An ability like this dismisses the level of your opponent, allowing you to kill anyone and anything. Not only that, but it's not a zanpakuto you need to use in combat. A character like this could easily just hide away somewhere and kill off every threat to them with a few sentences. This is actually far more powerful than the Death Note, since there's no apparent lag time and no limit as to what you can do. If you want to use the Death Note idea, I'd suggest dramatically limiting the capacity of your writing (as in, you can't kill someone directly using this, and you cannot create impossible to escape situations).
