Ganbare Gun (頑張る・ガン, Ganbare Gan, lit. "Do your best" Gun): During his fight with Azuma Genkaku, Ganta discovers an improved version of his Ganta Gun. This version has a faster and much more powerful bullet that causes patterned, black lines (shiny red-pink in the anime) to cover his body. However, in the anime only, Shiro is shown to have identical lines on the right-side of her face at the same time as Ganta's appear, this suggests that the Ganbare Gun is linked to Shiro and further suggesting that this BoS is the key Branch to open the Mother Goose System. This Branch of Sin is the only one that has not yet been copied by Toto Sakigami.
