Comment 1:

"Did you say Grace?" Wrench jumped in and answered:
"Hm, she's the first person I've met nice enough to give me a massage."


Comment 2:
"She's genuinely caring," Screw quickly added:
"Rather than being tightly wound, I prefer her way of tightening screws just right."


Comment 3:
Gear joined in at this point:
"Her intelligent mind is alluring and elegant as a well-engaged gearbox!"


Comment 4:
"And very rational," Oil muttered:
"In her dictionary, there's no room for 'a little' or moderate amount. It's all in precise 'milliliters'."

Official Introduction

"Is there something odd going on with your microphone's audio?"
"Hmm, it's possible that a stray hair got in..."
"Mind if I check your inner parts for you?"

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/dormmate 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.

Agent Details

Grace is a technical expert at Belobog Industries. She's the core talent in developing and patenting Belobog's in-Hollow machinery.
She's obsessed with gears, metal and wires — a true mechanical geek. She's eager to dismantle and study any machinery or equipment she takes an interest in: "Such sharp and strong lines, truly beautiful... I can't help but want to open it up and take a look."

Grace always shows extraordinary patience when dealing with machines, doting on the sophisticated metal constructions as if they were her own children.
According to the information at hand, Grace is probably the only one who can playfully refer to Koleda as "Sweet Pea" without receiving a kick in the shin.
Question: Based on Grace's understanding of machines, would she consider me one? I'm currently lacking a physical form, however, so I don't possess components like gears, metal, or wires.

Both of Grace's parents, who were research workers related to the Hollow, disappeared during a dangerous expedition into a Hollow, and were soon presumed dead. Grace was adopted by her parents' former friend, Khors, the previous president of Belobog Industries, and Koleda's father. As a result, Grace and Koleda are "sisters," though not related by blood.

Cooperation Notes

Agent Belle Circle Icon Belle
Is it just me... or does Grace sound just like a human talking to a cat whenever she's talking to machines?
Agent Wise Circle Icon Wise
You mean the way you talk to cats, right?
More importantly, is Fairy already thinking about philosophical questions like "Who am I?"

Grace can passionately go on and on about how amazing videotapes are without any repetition in over half an hour. Of course, no one knows that her love is for the beauty of machines, and the videotapes are just secondary to that.
Hmm... I don't have any research plans for today, so helping you with promotion sounds interesting. But it's quite rare for you to ask for my assistance. Could it be... There are films with a mechanical theme?!
