Arlan is the head of the Herta Space Station's security department, who does his best to protect both the researchers and the Curios they're ever so fascinated with. As Peppy's emergency contact, he shares a close bond with Asta's puppy, who sometimes imitates his injuries. I think that Arlan has an interesting kit as his skills require HP to use, so he pairs well with a reliable healer.
