Haschwalth (ハッシュヴァルト, Hasshuvaruto?) is Yhwach's right-hand man and is seemingly in charge of the Stern Ritter. He along with the rest of the Vandenreich was sent to deliver the message to declare war on Soul Socitey. Later Haschwalth and the Stern Ritter went with Yhwach to destroy the Soul Society. He kills the 13th Division's Sixth Seat, Hidetomo Kajomaru, in front of other Soul Reapers after breaking his resolve. Sometime later, he helps Yhwach in his plan to steal Yamamoto's bankai by accompanying the shape-shifting Stern Ritter Y, Royd Lloyd, and watches the latter defeat Kenpachi Zaraki rather easily. After Yamamoto's death, Haschwalth is told to convey to the other Stern Ritter that they were to raze Soul Society before Ichigo arrived. He watches his master fight Ichigo before being called back to their palace, before which he easily breaks Ichigo's bankai.
