Powers and Abilities
Immense Intelligence: Weekend repeatedly outmaneuvered most of her opponents with incredible ease. Also she had been preparing sufficient counter measures and studied her opponents and their abilities one year in advance.

Regeneration magic: This is Weekend's true specialty. Despite having moderate amounts of magic power, by preparing her offensive means in advance, Weekend can use this magic to it's fullest potential to both quickly recover from enemy attacks and to use her own offensive magic at any range, thus making attacking her let alone defending from her attacks incredibly difficult. She refers to it as 'false death and rebirth'.

Conventional weaponry: Weekend isn't above using normal weapons in case she ends up in situations in which her magic power would be exhausted or she gets trapped in a special prison in which she couldn't use magic anyway.
