WBaWC Extra Stage Theme: The Shining Law of the Strong Eating the Weak HD

Extra Stage Theme: The Shining Law of the Strong Eating the Weak from Touhou 17 Wily Beast and Weakest Creature. 輝かしき弱肉強食の掟 A really good Extra theme especially with that electric guitar and piano. It reminds me of PC-98 era a lot. I just wonder who are the Strong and Weak in this stage?
