Summary
D’s constant companion is his talking left hand, occasionally known as the Countenanced Carbuncle. This symbiotic entity has taken up residence in D’s hand, though the reasons behind it remain unclear. Fans affectionately refer to the hand as "Lefty," who possesses supernatural powers independent of his host and occasionally uses them to assist D. More often than not, however, Lefty prefers to sit back and let D do the work, interjecting with sarcastic remarks directed at his host.
