Vert

Vert is the human form of Green Heart, the CPU of Leanbox. She serves as a boss in-game and eventual party member. After banishing Purple Heart to the world beneath Celestia, she and the other Hearts return to their normal lives. Vert does not have a sister like the others, but she has a close relationship with Chika Hakozaki, who may or may not be related to her. An obsessed video gamer, Vert is usually mature with a calm composure who generally seems to be friendly, but at the same time, Vert will usually put her desires and needs before more important things and seems tired more than rarely due to often playing video games instead of work. Vert uses a drill on a rod/spear weapon.
