Scythe Ripper was a normal girl, born under the crescent moon of the night. Until, she was insanely injured by insane people in the Halloween night. 
She wandered across a dark forest, meeting a living pumpkin. Bonding with the pumpkin, for healing her health, she has to give the pumpkin her sanity.
Becoming the equivalent of the grim reaper.
She has friendly rivalry with Reaperess Magy.
Her presence alone alarms DJ Phantom, even though he has the reaper of the gear.
