You can place which ever skills you like in the four categories that equal up to his rank ^^ the points are for the future when we start allowing custom skills and if your character climbs up the ranks

Late edit: for example, since your char has a mastery in zanjutsu they'd be able to get master level zanjutsu skills. Now they wouldn't be as strong as a captain's or lieutenant's but they'd be able to perform the technique nonetheless. If they have a expert or practitioner level, then they'd only be able to reach that level. Hope that cleared some things up o3o if not, feel free to ask anything else
