The mark on [[Naruto]]'s hand is meant to give him a focal point for his [[chakra]] output, concentrating the Rasengan's strength on one specific point rather than dissipating it over a larger area. This does little to help him. Meanwhile, [[Orochimaru]] is in agony from the seal placed on him by the [[Third Hokage]]. With [[Kabuto]] unable to do anything for him, they decide to go looking for [[Tsunade]]. Kabuto tells him that she is in [[Tanzaku Quarters]], which [[Jiraiya]] also finds out in the course of his own investigation. In Tanzaku, Tsunade, a gambler with terrible luck, hits a winning struck, which causes her great concern.
