From Scarlet Blade Wiki
You gain Rank Points (abbreviated RP) by killing an Arkana of the opposite faction, or by killing certain NPC's (such as the Ranger and Warden in Viledon), or by selling Memory Chips. The amount of rank points earned by killing an Arkana of the opposite faction will depend on the killed Arkana's ranking; the higher her rank the more RP she'll reward to the Arkana who killed her.
When you reach a certain amount of Rank Points (rank threshold) your Arkana will be awarded the next PvP grade, indicated by the icon displayed on the left of the name. You can see your ranking by pressing C (default setting) and selecting the Ranking Info tab.
You can also spend Rank Points to buy items available in the dedicated vending machine including cyberclusters, HP/SP Crisis, Unique Earings, Mech/Cyberskin upgrades, etc. If by doing so your total points drop below a rank threshold, your Arkana will return to the previous rank. Rank points are also useful to enable an Arkana to use special advanced and more powerful equipment such as Major Mechs and Major Cyberskins. Currently, the total amount of RP required to utilize Level 35 Major Mechs and Cyberskins is 1057800 RP ("1st Order Agent" rank).
