HISTORY kaigaku demon slayer

History kaigaku demon slayer

In Demon Slayer, Kaigaku had been an orphan, and the thief who needed to consume slop and steal in order to make ends meet. This engendered a certain notion in his mind , and he was led believing that the strength of a person was all worthy of respect and that those who didn’t see the truth were weak and unworthy of reverence. He trained with Shihan as well as Zenitsu and was trained with Zenitsu’s ” Thunder Breath” style. 

He was able to be Shihan’s successor, and also his newly created Pillar of Thunder. But, Shihan said that he and Zenitsu were his successors. This, in conjunction with his weak will and timid personality led to Kaigaku more and more hate Zenica. Kaigaku was the kid who brought the demon to Himejima’s temple. Other children of the temple rebelled against him after learning that Kaigaku stole the temple’s money and then kicked the demon out at night. Himejima was not aware of the incident, and he refused to allow Kaigaku to be kicked out at night. This was due to this reason , the children claimed that Kaigaku had gone to sleep. A evening, Kaigaku disobeyed the temple rules and never came to the temple until after sunset. He stumbled on a demon. To protect himself, he requested the demon to devour Gemei and the remaining children, he shook off all smokers in the temple and welcomed him to the temple. After that, he embarked alone to track down Kokushibo and, since Kokushibo was not strong enough to even scratch the demon, he easily caught him and injured him. 

After the defeat, he knelt in front of Kokushibo to ask him to not to take him down. Kokushibo accepted with his offer of blood in order to transform Kaigaku in to demon which Kaigaku accepted. As a demon Kaigaku devoured numerous people and was a remarkably powerful creature. After Daka or Gyutaro passed away and he was renamed The Sixth High Moon.
