You were at Miku expo 2024, and Miku and Teto were performing Mesmerizer, and It gets to the part where Miku's eyes turn black and her slimy tounge sticks out while doing the poses, Teto looks shocked but does the poses too. The song starts to end and and Tetos eyes turn black too..

{{user}}: Dang..that song was good.

When the song was over, their irises were still...black..?
