Abilities & Powers
- Destroyer of Worlds - Her main weapon. A metallic gold-coated rifle, named "Destroyer of Worlds", which can transform into two modes: Rifle & Sword. The gun also had a symbol "VIII (Eight)" crafted on the gun's left. However, she also had multiple powers from other Puella Magi: like:

She also has the ability to clean soul gems, however if she absorb too much grief, she would turn against her allies.
If Shirakami had collected 8 Puella Magi powers, she can assume the ability called "Complete form", However if she had only 5 powers obtained, her form is dubbed as "Half-complete form"
She can activate them via her will power, The armor changes into a new one, and her chest armor changes too. The main 5 slots contain the soul gem symbols of Madoka, Homura, Mami, Sayaka, & Kyouko.She also can summon the 5 girls, as soild holographs. They can attack the witches via command or their will. Shirakami can also use the ultimate power called "Trump Card Finisher", which commands the 5 Magical Girls (Along with her ultimate shot) to finish of a witch with their attacks (for example: Madoka's ultimate arrow, Homura's multiple bazookas, Mami's Tiro Finale, and the KyouSaya Formation (which is the formation between Sayaka and Kyouko's sword & spear thrust)) in one time. This was similar to Kamen Rider Diend Complete Form's Final Attack Ride.
- She is an homage to the three characters:
- Ultraman Ginga & Rockman X: using multiple powers, and the parts change color corresponding to their forms.
- Kamen Rider Decade: also tasked to help the character's alternate reality counterparts, and also bears the "destroyer of worlds" title.
- Her costume somehow bears a resemblance to the White Wizard from Kamen Rider Wizard.
