Aipii

Aipii (あいぴー) was the third of the Four Kizuna AI, but since 14 June 2020, she is now, along with her sister Love-chan, in charge of their own channel called appropriately love-pii channel

Personality
Aipii's character is energetic and cheerful. She is fond of playing videogames and also she has a tomboyish personality (denoted for her short haircut, her hoodie and her shorts), in comparison to her sister Love-chan, who has a more delicate and refined demeanor.

Background
Originally, Aipii was one of the Four Kizuna AI, which was a initiative of the at the time Kizuna Ai's company, Activ8, to diversify Ai-chan's content. The project was ill fated because of a series of managerial mishaps and rumors, along with a series of scandals related with the mistreatment of virtual talents on other VTuber companies.

Eventually, several decisions were taken, such as giving Kizuna-Ai new "sisters" identification markers and a nickname. In the case of Aipii she was given a hairpin with the design of a yellow asterisk (*). Nonetheless, after a deep restructuring of A.I. Channel and the creation of Kizuna AI Inc., Aipii (and by extension her sister Love-chan) was given a new channel and she will no longer feature on the Kizuna AI's channel. The transition was concluded when she was given a new 2D avatar and "Aipii" become her official name.

Retirement
After a couple of hiatuses on the Love-pii channel, on the 08/17/2020 the official Kizuna A.I. Inc. Twitter announced that Aipii would cease all activities (retire) after the completion and release of Uinatsu. No official statement was given as to why Aipii would retire.

On 13 September, Uinatsu was released and Aipii officially retired. After a couple of days Love-pii channel was changed to loveちゃんねる, and her sister Love-chan returned to streaming.

On 16 September Aipii made her last to tell her fans that she saw the tribute video "Stargazer".
