Here is the Smiling Duelist! The melee cousin of Happy Battler! He saw Happy Battler on behalf of the defenders so he decided to join to. (If any more Duelist variants are made then it would be cool if you did it based on the Periastron Series please k thanks)
The sword he has is the Azure Periastron Alpha. He is also the first defender with a Periastron. (I think) And the second defender to have a Parry ability. (first to Pan Noob (I think)) And C2A
