Understand what reborn means, but isn't that essentially what happens when you kill Oro (except mount, gems, spouse, and charm), why would you make it so everyone looses everything. I would suggest that Hokage (50 Oro kills + greater) be able to restart are chunnin level with gems and for each kill past 50 they recieve a bonus of their choosing, (ie gem per level, charm, or gold) kind of like the christmas bonus.
Would like to know if the kekkie genkai would be available in pvp or not?
Also would it use chakra like in real life? (if so then why not make it like seven star and give a bonus effect that lasts for duration and can be used in pvp and forest but not ninja accademy?)
