Profile:

Grace Howard is the eccentric, machine-obsessed R&D specialist of Belobog Heavy Industries, and adoptive sister to Belobog's current president, Koleda. She is responsible for the new-generation of in-Hollow Smart Machinery the company uses. Whilst having a notable interest in dismantling and examining machinery, Grace also sees creations of her own as her 'children,' ready to protect them at any given moment. Outside of mechanics and engineering, Grace Howard is known for her acrobatic prowess in combat, capable of dodging various forms of gunfire and etheric attacks, whilst fighting back with a weaponized nail gun and electric grenades.

History:

Grace Howard was born to two Hollow researchers who were more focused on their work than on their child. Their dedication to their research led them to forget to eat and to prepare food for their daughter. Despite this, Grace cherished the time they spent together, as her parents soon vanished while inside a Hollow. Now orphaned, Grace was taken in by Khors Belobog, a close friend of her parents. With her adoption, she became the adoptive sister to Koleda and formed a close bond with her, playfully calling her 'Sweet Pea,' whilst calling her new guardian 'Uncle Khors.' When Khors suddenly vanished one night and was accused with running with company funds, Grace was adamant that he was not guilty and continued to look up to him, while Koleda began to detest him.[1]

With a strong interest in all things mechanical, Grace attended the Roose Institute of Technology to study and become a certified mechanic. Her obsession with machines led her to become antisocial with anyone organic, earning her the moniker 'The Frosty Cold Iron Witch,' or simply 'Iron Witch,' from her classmate Betty Brenda.[2] During her time there, her teacher commended her as his most exceptional student, adding, 'Nothing can hold you back.'

Upon graduating, Grace returned home to work for Belobog Heavy Industries, now under Koleda's leadership. She began a large-scale project to create lighter, easier-to-mass-produce, and maintain In-Hollow Smart Machinery, using schematics of Khors' prototype as a base. However, her main goal was to create a 'child.' After enduring countless days, nights, and minor injuries, Grace nearly had the prototype working when the system failed to stabilize at the final moment. The following day, recalling her teacher's advice, she realised that Ether substance stimulation might be required for the system to fully stabilize. Taking her prototype into a Hollow, she successfully activated her 'child' just moments before Ethereals attacked; her new 'child' protected her from harm and was later named Greta.[3] Grace went on to produce two other 'children', Friday and Hans.
