He was once the leader of the Seven Swordsmen of the Mist before being outsted for his incredibly violent acts against other nations. In his rage, he then founded Chigakure where the rest of the Jigoku Clan members reside. Chiizu is also known for leading many other violent acts within Kiragakure that he has transferred over to Chigakure, except with the freedom of being it's village's leader.
It would be revealed that Chiizu committed grave acts towards other villages, despite him believing it is for the sake of Kirigakure. He was even the teacher of Kirigakure Academy where he was known for putting his own students to the fight to the death in order to be deemed worthy to train under him. He even would put those that passed through even more brutal training deemed inhumane by many others and was eventually demoted from his positions thanks to Suijin Hōzuki, the Third Mizukage. Among other things, Chiizu would then defeat from Kiragakure taking Samehada with him believing he is "worthy" of a blade. 
==Background==
===The Demon of Kiragakure===
Over 20 years ago during the reign of the Second Mizukage, Chiizu served as a member of the main fighting force being able to take out ninja that even dared to harm Kiri. Chiizu was an effective ninja and feared for his unique Kekkei Genkai, the Blood Release allowing him to control his own blood and others for attacks. He was also infamous for being proficient with the sword, most notably Samehada that was passed to him from the previous user. It was thanks to these actions that made Chiizu known as the "Demon of Kirigakure." Chiizu was pleased at the work he has to do and as a member of the infamous Jigoku Clan, he feels like he must continue to bring bloodshed upon others.
However, years later, Chiizu's reign of violence would come to a halt where there Second Mizukage died in combat and were deciding the next Mizukage. Chiizu felt he should've been appointed to the role as he wanted to bring forth a group that, every few years, scout out an entire era and take out villages that may be threatening to Kiri known as the Eradication Pact. Chiizu felt that, with that plan in motion, Kiri will help be seen as the most threatening village of the Five Great Nations and anyone would dare not to combat them. However, the elders have already decided to name Suijin Hōzuki as the next Kage as he was the nephew of the Second Mizukage and has very promising abilities, skill, and knowledge to help lead Kiri to a better place. Annoyed, Chiizu relunctly accepts the decision and hopes that he can ask Suijin to approve his pact when the time is right.
Chiizu waited a few years serving under Suijin in hopes of getting onto his good side. He has completed many missions and taken down numerous of threats that tried to harm Kiri. It was one day during a heavy rainfall where Chiizu explains to Suijin about his Eradication Pact where at every few years, he will lead a squad of ninja to scout out any potential threats to Kiri and take them out no questions asked. Suijin, however, rejected the pact saying that something like that in place would lead to more enemies than allies. Chiizu argued that Kiri doesn't need allies as long they strike first and hard, frightening the other nations. Suijin scolds Chiizu for his way of thinking and tells him that he would not be allowed to do things that violent. An upset Chiizu then decided to prove Suijin wrong by taking matters into his own hands.
===The Defector of Kiri===
Chiizu, using a combination of shadow clones and his affinity for sneaking, sneaks out past Kiri's borders in order to start his plan. Chiizu aims to make himself known with his plan to make Kiri seem to be t he most feared village of them all. Chiizu then gathered a small squad of his fellow Jigoku Clan members and would go on a killing spree of smaller villages. He would also pillage all of their supplies for their own needs. However, Suijin began to notice that Chiizu would get up later than usual prompting him for a response. Chiizu's excuse was mainly to say he was training himself as his clan is stronger a night, and Suijin brushes his suspicions off at first.
However, Chiizu's actions would catch up to him where, another few years at another attack, Chiizu thought he killed off another village, but one of the villagers there was still alive and recognized where Chiizu came from thanks to his Kiri-style ninja headband. The man revealed about Chiizu's actions to Suijin who was appalled to learn that Chiizu was operating against his orders. Chiizu angrily protests saying this is what Kiri needs: to be feared. However, Suijin dismisses his claims and said he acted out against himself and Kiri itself and sentenced Chiizu to be locked away for an indefinite amount of time. He also takes away Chiizu's position as the head of Kirigakure Academy.
==Personality==
A man who is proud of his savagery, Chiizu is an extremely hostile and violent man who always prefers to resort to violence to get his way. Chiizu rarely expresses any other emotion other than anger; though he will often have a stoic look on his face whenever he isn't in action.
==Abilities==
Being the former leader of the Seven Ninja Swordsmen of the Mist and the second-in-command to the Mizukage, Chiizu held a lot of power during his time at Kirigakure. He was even appointed as the head teacher of Kirigakure where he taught under a ruthless class where others had to kill each other to proceed.
