Genius: When Gin was younger he was hailed as a child genius. He was highly proficient in his classes at the Shinigami Academy and therefore he graduated far ahead of those around his age and gained a seated position in the 5th division while still a child.
Master Swordsmanship Specialist: Gin is a highly proficient combatant. In combat he doesn't seem the least bit taken back by the abilities of his opponent, even when they seemingly have an advantage. He fights with seemingly no effort behind his attacks. His ability to wield his combat skills where evident even when he was a child. He easily defeated and killed the former third seat of the 5th division, who by rank should have been more powerful and skilled then him.

Shinso (神鎗; lit. Divine Spear, Viz: Sacred Spear): It looks like a wakizashi (Japanese short sword) normally and the guard is shaped like an 'S'.
Shikai Special Ability: In its Shikai, Shinsō's blade glows white and extends at high speed to impale Gin's opponents from a distance. The blade also carries tremendous force when extending, as seen when Gin pushes both Ichigo Kurosaki and the giant Jidanbō out from under the Seireitei gate, despite the latter being firmly braced under it. In addition, Gin can maintain the extension and swing the activated Shinsō in wide arcs, attacking multiple targets quickly and simultaneously.
