So #1, the SSS rank letter appears as grey and broken, this happens whenever the rank you get in Pump it Up doesn't count because you ran out of health at some point in the song. #2, it says Mission Failure because he was actually playing Ladybug in Mission Zone, where he had to hit 300 or more notes, which he clearly didn't do as the game over happened before any notes even showed up. This is because the Mission Zone chart for this specific beatmap is literally filled from top to bottom with mines (including at the beginning, which can cause you to fail almost instantly, which is what happened in this scenario) except for in the spots where the notes (which are invisible) are. Because no notes showed up and Ronaldo got 0 out of 0 notes, the game counted it as an SSS because it's still, technically, 100%. But he still died due to not knowing about those stupid mines, and likely misinterpreted the SSS as him passing. Ah, my poor (mostly) innocent Ronaldo.

I KNOW THE ORIGINAL SCENE IS AN ANIME REFERENCE BUT I THOUGHT OF THAT PART OF MGR WHERE YOU PUNCH ARMSTRONG REPEATEDLY WHEN WATCHING THAT SCENE
