Just a few days ago during Niconico Tokaigi 2018, we were surprised with the Pearl and Marina amiibo bundle. During the event, attendees received a special concert of a hologram of Pearl and Marina. Very similar to the concert held at Japan Expo 2016, showcasing holograms of the Squid Sisters. During the event, the Squid Sisters made an appearance.

Nintendo Japan officially released the event from Niconico Tokaigi and you can view it here:

A concert poster was revealed back in December from the official Splatoon twitter account. Could we potentially see this concert come e3 or something special? You can download the concert’s poster at a dimension of 849 x 1200 below the tweet.
