Tobita Danzo ( 鳶田 段蔵 ), more commonly known as Jiraia the Spider ( 蜘蛛手の地雷亜 ), was born into a samurai clan and was a prodigy in the ninja arts. He used to be a member of the Oniwabanshuu,working under the Shogun, the founder and former leader of the Hyakka,former leader of the Red Spiders (Benigumoto) and Tsukuyo's master.
Tobita Danzo was born to a country samurai in Iga, and mastered ninja techniques at a very young age. His natural aptitude had people calling him a prodigy. The samurai in Iga were fighting year round, and the Tobita family was one of the larger families in Iga, so with a talented son like him in line to take over, his families' foes weren't just going to stand by idly. All of his family were wiped out, except for himself and his younger sister, who were taken hostage by the enemy in order to gain Danzo's cooperation and obedience. He did everything they asked, however his sister couldn't stand seeing her brother like that, and so that he would stop pushing himself for her sake, and live freely, she commited suicide.
Later on, while working for the former Shogun, he burned his own face in order to work undercover. He would sacrifice his own body to perform any dirty and dangerous job. His devotion was his only motivation, and it struck fear into anyone around him. He abandoned his face, his name and his very existence for the sake of being able to change identities at will.
20 years before present day, when the Amanto invaded, the Bakufu and Shogun were terrified and cracked in no time.However, the Oniwabanshuu didn't. A clan called The Hawks said that this was the time to fight and show their skills, while the moderates said that they should accept the decision from the higher-ups. And thus, they had a factional dispute on their hands. The Hawks became a nuisance to the Shogun, and Jiraia was ordered to erase them all from history, even though they were his comrades. He completed his task with ease, but when sitting infront of the Shogun himself,he suddenly attacked in an attempt to assassinate him and make history change its course. However, Zenzou's Father was acting as a duplicate the whole time. They fought, and he injured Zenzou's Father's legs. By killing his own comrades, Jiraia's position among the Oniwabanshuu had been tarnished. Surrounded by the Oniwaban, he still managed to escape, despite reciving critical injuries. Jiraia was the monster the Oniwaban failed to eliminate and let loose into the world, as stated by Zenzou in Episode 179.
After this incident, he somehow managed to end up in Yoshiwara, where he became the original head of the Hyakka and Tsukuyo's master. He taught Tsukuyo everything he knew, and made her abandon her life as a woman in order to become strong and able to protect what she believes in. He trained her from a young age to create a hardened warrior, and as a final lesson, four years before present time he pretended to sacrifice himself and die in a major fire in Yoshiwara, protecting Tsukuyo, as stated by Hinowa in Episode 178.
He had black shaggy hair and wore a dark colored hakama and haori. His most notable feature was his horribly burnt face and his large bulging eyes. He could conceal his face using a special face-mask.
At a young age, his family were all wiped out by other samurai, and he felt ashamed of his skills that had kept him alive, while everyone else was killed. Holding his sister hostage, the enemy, the ones who had also wiped out his family, forced him to obey them and work as their underling. This gave birth to Jiraia's twisted sense of devotion, and led him to literally sacrifice his sense of self in devotion to his work. This was his escape from the hatred, sorrow and shame of serving the ones who exterminated his family. He forgot his identity and focused on mechanically carrying out mission after mission. In present day, he was still haunted by the fact that he couldn't protect his sister, who wanted her brother to live freely and therefore commited suicide. In Episode 180, Zenzou thought that this was the reason Jiraia wanted to die in the worst possible way; to become the enemy of his own beloved student and die by her hands, as a self-inflicted punishment for failing to protect his sister. However, this was quickly disapproved by Jiraia himself, who said that the reason was that he was just scared of losing anything else, a coward who was too scared to bear the burden. He then said that the reason he taught Tsukuyo was that she wanted to protect Yoshiwara and Hinowa, and tried to shoulder everything on her small back. He didn't want her to get hurt like he was. He continued that in the end, he was scared of losing someone else again, and that he wasn't protecting her or his sister, but only himself. And he grew tired of himself. He then apologized to Tsukuyo for forcing her to shoulder a worthless burden.
