"Legend has it that Dai Ryusaki created a mind-enhancing potion that was super powerful... The potion was deemed dangerous, so Ryusaki was arrested and the potion destroyed! Rumour has it that, before he arrested, Ryusaki was able to hide a Dark Scroll with the potion ingredients. To this day, though, no one knows if the Dark Scroll actually exists... or what its contents may be!"
