Trivia

 * The first video aired was on 31 March. Many initially thought this was an early April Fool's joke, but were both surprised and angered when the channel was confirmed official, asking why the three year old franchise had decided to suddenly make a VTuber channel. An apology video was later made, with Hacka Doll #1 addressing fan questions and complaints.
 * With the official announcement that the Hacka Doll franchise will be shut down on 15 August 2019, the channel is confirmed to remain, however it is unknown whether it will continue to produce more content in the future.
