Ganta Igarashi

Ganta Igarashi (五十嵐 丸太) aka Woodpecker, the main protagonist of the story, is a seemingly harmless, ordinary middle school boy who is framed for the slaughter of his entire class, perpetrated by the mysterious Red Man. Sentenced to 'death' after a phony trial, he is sent to Deadman Wonderland, where he is initially confused and frightened by the brutality of the prison. Shortly after arriving, Ganta discovers he can manipulate his blood and, thus, is deemed a Deadman. Ganta appears to have gained this power from a shard of crimson crystal the Red Man fired into his chest after the massacre at the school.

As a Deadman, Ganta is forced to fight and survive in the Carnival Corpse under the moniker Woodpecker while trying to locate the Red Man, who apparently is held captive in Deadman Wonderland. Ganta's power, dubbed the Ganta Gun by Senji, allows Ganta to gather variable quantities of blood in the palm of his hand and then shoot them at high speed, as if they were bullets. While advantageous as a long-range attack, due to Ganta's small stature, this also puts him at risk of experiencing symptoms of excessive blood loss.

Ganta participated in Scar Chain's attempt to escape from DW, and helped several members escape along with video and audio evidence of the atrocities being committed below the prison. Ganta, however, chose to remain behind to continue his search for the Red Man. Shortly after these events, Ganta's power began to change, evident by a strange tattoo-like mark radiating out from the crystal in his chest. His Ganta Gun now emits a much more powerful blast than before, though it is much less controllable and causes him physical pain.

He has feelings for his childhood friend Shiro, ironically the very same Red Man that he's bent on killing out of revenge. When he was out of Deadman Wonderland, he realized that fact and confronted her about it.

Abilities
Branch of Sin: As a Deadman, Ganta possesses a Branch of Sin. This allows him to freely control his blood. He usually bites his thumb to forcedly bring his blood out. He got this ability when he inhaled one of the Red Diamonds during the Great Tokyo Earthquake.


 * Ganta_Gun.pngBranch of Sin: Ganta Gun: Ganta collectes his blood in his right hand and shoots it away (simillar to a bullet, hence the name Gun). He first uses this ability at the first day he was in DW. A boulder was thrown down with the intent to kill him and Ganta fires his Ganta Gun and crushes the boulder. He has trained his Ganta Gun to be faster and stronger with the help of Crow. The bullet of blood can also reflect against other objects, changing the course of the bullet.


 * Advanced_Ganta_Gun.pngBranch of Sin: Advanced Ganta Gun: During his fight with the Wretched Egg, he discovers an improved version of his Ganta Gun. This version has a faster and stronger bullet and cover his body with patterned black lines. The new bullet is also much more powerful and much faster than the original. This improved BoS has not been copied by Toto Sakigami yet and this leads to the conclusion that this Branch of Sin is probably the key Branch to open the Mother Goose System.

Trivia

 * Ganta's Branch of Sin, Ganta Gun, is the only one known to evolve over time.
