Chihiro Yuki's little sister, Hiyori, recently made a Twitter account.
The problem is, officially Anycolor does not acknowledge the fact that the character Chihiro Yuki has a little sister.
To skirt around this issue, Hiyori doesn't say directly that she's Chihiro's sister - she just retweets her a lot, and makes it known that she's a big fan, and Chihiro follows her while alluding to the fact that her little sister has made a Twitter account.
Hiyori isn't a VTuber nor makes any kind of content at all - it's just a personal account where she talks about anime and manga with her sister's fans who are now following her.
Some people might call it leeching.
Today Chihiro reveals to her audience via Twitcast that Anycolor has requested the deletion of her sister's Twitter account - her objection is "and she was having so much too".
So who was in the wrong here?
Is this the fabled Nijisanji freedom I keep hearing about? Talk about a draconian black company. Making totally unrelated people delete their twitter accounts.
