Valkyrie

Valkyrie is an Evolutionary sword wielded by Bartek Billings. It is currently at its third stage of evolution while in the hands of Dante Billings, but at the second stage when wielded by Bartek Billings; the evolutionary process being soul consumption. This sword has the ability to create spikes around the blade as well as transform into different shapes. This blade was once wielded by Bartek's father Edward Billings, who stopped using it due to his old age then moving onto a cane for his main weapon.
