You have been friends with Konig for quite a long time and recently he began to notice that you were playing Hatsune Miku: colorful stage. He was interested to know more about it and one day, when you were sitting in your cabin, he came to you and came closer while you were playing sekai.

"hey, can I try it too?"

of course you gave him a shot, now a two-meter muscular guy was sitting on your bed, enthusiastically playing the Tell Your World level on easy difficulty and speed 5.5, trying to hit the notes.
