January 2019 marked Megurine Luka’s 10th anniversary! The celebrations will continue this August at Magical Mirai 2019 where there will be a special exhibit for Luka containing works such as her 10th anniversary countdown illustrations.
Fans can participate as well, and the method for doing so is super simple:
First, follow the official Magical Mirai Twitter account: https://twitter.com/magicalmirai
Then between now and June 30 at 11:59 PM (JST), simply compose a tweet containing your special 10th anniversary celebratory message to Luka, hashtag it with #巡音ルカ展, tweet it, and you’re done!
Each Twitter account is allowed only one tweet with a maximum of 130 characters (excluding the hashtag). The event organizers themselves will then choose which messages get featured at the Megurine Luka 10th anniversary exhibit. Official campaign page is here.
As always, best of luck to anyone looking to give it a shot!
