Sashihara Rino has ‘officially’ been moved to HKT48. The staff has removed her profile from AKB48’s “Team A” category and it has been added to the HKT48 official member page. However, she is currently not under “Team H” or “Research Student”, she has a special category all to herself; “Team Undecided”.

Lastly, Sashihara has not been completely removed from AKB48’s homepage. Instead she has been moved to the bottom, below the research students under “HKT48”. Fans are unsure if this means she will be participating in the Tokyo Dome concert with AKB48 or if staff just wanted to keep her on AKB48’s page in some way.
