Slay the Sleep Demon

This song is a high-energy, mock battle-style cheer track that portrays sleepiness as a final-boss level enemy. Under Captain Teto's command, everyone bands together and tries to fight off drowsiness using nothing but hype, spirit, and momentum. However, the "strategy" quickly goes off the rails, with goofy twists like stocking up on massive amounts of French bread.
The gunfire sounds and shouted calls are all metaphors for "stay awake" - more like a ritual to pump yourself up when you're about to give in to sleep rather than an actual fight. In the end, sleepiness never truly goes away, and that punchline turns ordinary human weakness into something charming and funny.
