Bonnie Harris

A shapeshifter from the Overworld and the Second Lieutenant to Oliver West, Bonnie is an extremely bubbly and sweet girl who specialises in fighting as a frontliner with her sword and shield. Her short, chubby, but muscular body allows her to be a strong tank and a useful asset in the war, especially to her officer who specialises in ranged combat with a bow.

Sneaking into the Coreworld, Bonnie seaked out Riley after rumours broke out in the Overworld of a mortal who broke from Maria's mind control in an attempt to try and convince her and her allies to join them in the efforts in the war against Maria. Bonnie ends up joining the University that Shizuka, Fuyuko, and Riley attend as a BSc Sports and Exercise Science student and becomes one of Shizuka's flat mates.

Despite her constant denying, Bonnie is very obviously in love with Oliver.
