This is based in the bleach universe however it will still be an alternate timeline, in other words the Gotei 13 (Captains, Vice-captains and other “Important” characters) will remain the same however, Ichigo and his band of misfits (Orihime, Sado & Ishida) never existed.
As far as applications go I’ll not only be looking at the quality of the actual story line generated for your character & party slots, but also who helps develop the “World” the most (I.E. what is the name of your teacher, who are your friends, ECT). Please supply both a 1st level and a 20th level character sheet with your application. As far as fluff goes I’ll be incredibly lenient as I feel the appearance and feel of things shouldn’t be too big an issue, so If you want to have a Shikai that looks and acts like a tomahawk missile that’s fine but remember that it at least has to be somewhat mechanically stable.
A few guidelines…
Your characters all come from the same high school, so look at ages between 14 – 18 (maybe 19/20 at most to account for failing a year or two).
Consider how your character became spiritually aware… did a hollow try to eat him/her as a child, where you eating a bag of chips and accidently ate a tiny hollow and nearly choked to death, Etc.…
As stated above generally attempt to help me build the NPC world
