Welcome to the Ina Week of Hololive Funkin', where she is the newest AniTuber that you and BF will face off against in a rhythm battle, since only by defeating her can you escape this world, and you get to do in on quite a whole lot of songs:
Weight Of The Universe
Our Nonstop Story
Bordering Final Story
Stand By Me
Defeat Ina from Hololive in some of the most funkin' songs out there!
You will make a choice between the story mode and free play mode, after which, in either case, give your best to reach the end of the songs by playing their notes according to the charts, which is how victory is achieved.
To do it, press arrow keys at the same time as the identical arrow symbols match above BF's head. Don't miss doing it too many times in a row, or you lose and have to start again from scratch. Good luck, enjoy!
