Hacka Doll

Hacka Doll(ハッカドール) are a group of Japanese Virtual Youtubers, also navigators from the Hacka Doll news app and characters from the anime series of the same name.

The channel mainly features Hacka Doll #1 (female, blonde hair) but there is also a video with #3 (male, blue hair). Hacka Doll #2 (female, pink hair), though she has yet to make a full video appearance, is sometimes seen in bumper panel art or during Hacka Doll #1's references to her.

Introduction Video
Hacka Doll #1's introduction.

Personality
Hacka Doll #1 is very energetic and always optimistic, but somewhat klutzy. Hacka Doll #2 is quiet and reserved compared to #1, but is quite airheaded herself.

Trivia

 * The first video aired was on March 31st. 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.
