Tatsuki Fujimoto, the author of Chainsaw Man was recently banned from Twitter for breaking the age restriction rules. He had an additional account by the name of Koharu Nagyama, who he portrayed as his little sister in 3rd grade.
Who would’ve guessed someone pretending to be an elementary school girl would get banned on Twitter, the new set of rules by Elon Musk are not a joke.
While it was obviously a joke account by Tatsuki Fujimoto to promote his two great mangas, Chainsaw Man and Fire Punch. Still, it doesn’t authorize pretending to be an elementary school girl on Twitter.
The editor of Chainsaw Man manga addresses that they’re working with Twitter to get this issue resolved as soon as possible and were soon able to get the account recovered and online.

Why was Tatsuki Fujimoto banned from Twitter?

The official editor for the Chainsaw Man manga tweeted later that the fake little sister account Koharu Nagyama wasn’t banned for impersonating Tatsuki Fujimoto’s little sister. But because Twitter doesn’t allow account anyone under the age of 13 to create an account.
Tatsuki Fujimoto created a new Twitter account to reply to his editor’s tweet and begged him to get the account reinstated.
This whole misunderstanding was caused by Tatsuki Fujimoto himself when he pretended to be his little sister to tweet his reactions to the anime series, this whole thing would’ve been avoided if he was didn’t keep his identity a secret.
Koharu Nagyama, the supposed little sister account has the following description “My name is Koharu Nagayama and I am in the third grade of elementary school. I made a Twitter account in Class. I like Fire Punch and Chainsaw Man. thank you.
This account was banned from Twitter a while back but it is currently live with all the former tweets and episode reactions.
Editor Shinhei Lin tweeted about the current situation regarding Tatsuki Fujimoto’s little sister and that they are currently conversing with Twitter to get this issue resolved: “We have been informed that Tatsuki Fujimoto’s younger sister Koharu-chan (@nagayama_koharu) has been locked due to her age. My brother is currently in contact with Twitter.”
Tatsuki Fujimoto and his new Twitter Account
After getting his official account banned due to the breach of age-related violations, Tatsuki Fujimoto created a new account by the name of Ashitaka Eva (@Ashitaka_Eva) and went live to clear the issue about his account getting banned:
While Fujimoto Tatsuki created the new account to address the issue, no one believed that was really him so he had to post the old concept art for the series, Chainsaw Man to prove that it really was him.
And much like hundreds of others, I also find the whole situation hilarious how Tatsuki Fujimoto had to jump hoops to prove it was him.
However, after his old account (Koharu Nagyama) was restored, Tatsuki Fujimoto deleted the new account.
