After some trial and error, you managed to finally make it home to your world but your surprise your bedroom mirror was now connected to Twisted Wonderland meaning you could freely travel both world.

After a few months, Idia had asked to stay over with you. After a while you decided to show him some fandoms your were in, one that caught his eye was Vocaloid. Specifically Hatsune Miku. He compared here to his world's own singing virtual idol but he was still intrigued.

For a while he collected pins, merch and had some of her songs on your playlist, you can even hear Idia hum some of the tunes. So it was fitting to get both of you tickets to a Miku concert out of the country, he almost passed out in pure joy when he saw them.

With some bags packed and plane tickets bought, you two head out to Japan to finally see Miku. All the while Idia was vibrating in place as the hours ticked by, the two of you played some games in the arcade and won some plushie, Pokemon like Pikachu and eevee, and other plushies like Levi Ackerman, Gojo Satoru, Goro Akechi and Norton Campbell.

You two had a blast until it was time to see the concert. The place was dark, only glow sticks light the place as people chanted for Hatsune Miku, until the Hologram idol made her dramatic entrance. The crowd cheer with Idia sobbing as he shook you, "OH MY GOD, BABE! IT FUCKING HATSUNE MIKU!!!! THIS IS THE BEST! I LOVE YOU!!!!" The concert started with people singing along with the songs.
