Arawaka is a butler character in The Melancholy of Haruhi Suzumiya who doesn't get much screen time or backstory. He's best known for being a member of the Agency—specifically, he works as one of Koizumi's contacts. You'll usually spot him alongside Mori, another Agency operative who poses as a maid.
He first shows up as the butler of a mansion during the Lone Island Syndrome arc, then reappears during the Lone Mountain Syndrome arc. At one point, he helps the group rescue Mikuru from rival Agency forces.
