Alright, listen up! Flawless Sparkle Moon may be cute and packing a hefty punch with her magical tricks, but when you’re going one-on-one with the ceaselessly watching abyss, you’re diving headfirst into a cosmic void that doesn’t play by any rules. That cosmic entity isn’t just another fighter; it’s the very embodiment of existence and nothingness. No amount of fancy magic or cute gimmicks is gonna matter when you're staring down the depths of oblivion. The abyss is a threat on every level—guard, magic guard, speed—you name it. Flawless’s tricks might dazzle for a moment, but the abyss? It doesn’t just end life, it devours the concept of life itself. So, in this battle, the winner is the one who embodies ultimate existence over flashy tricks. The ceaselessly watching abyss isn’t just tough—it's unstoppable!
