Is Ending 2 that you get stabbed during the 3rd Ascension game? Or is that not considered an ending.
If it's not an ending, how do you prevent that? I talked to people on the 1st floor about the green haired chick and one of them referred to a "hotel", but I don't see any hotels in the game.
EDIT: I used Mtool to bypass the bad ending in the last ascension match. From the switches and variables I changed I can tell that you'll miss a bit of content with "disabling" her friends who come to her rescue(it has something to do with sleeping pills, but I dunno what else). It just wasn't clear what the next step was. I was doing "dog races" with Hibika as a contestant and I'd done a lot of training, don't know where I was lacking any.
The save is attached below, if you use citizen cards you will win every time as I've given her 50k(not enough to buy cards).
