In a reality where Gloom, the Rat Hacker, lives off of hacking illegal tri-web sites, he found a golden opportunity where a "client" approached him and offered the chance for a proper clean job at the Drums. All he has to do is enter the VR simulation provided and complete some tasks. However, the Gloom intends to rope a drumer, his friend Guard, in order to get through a loophole.
Now both of them must face the consequences of the Gloom's actions as you number sequence your way through the towers, earn fragments and your right to Drumhood.
You will order numbers from least to most to deal extra damage. Use items to turn the tide of the battle in your favor. During enemy phase, you must surpass the enemy's numbers in order to reduce some damage from the enemy.
