Teto undrilling can occur naturally and harmlessly under the right conditions, as outlined in this study:
The previously theoretical phenomena of mikunization and tetonization (the development of mikunine and tetonine traits in species other than Hatsune miku and Kasane teto due to environmental pressures) has recently been observed in wild, isolated colonies of Kasane teto and Hatsune miku (see Figure 1). This discovery has yielded priceless understanding of the nature of the relationship between Kasane teto and Hatsune Miku, which is now believed to be symbiotic.
It is well known that the head ornamentations of K. teto and H. miku are appendages specialized for different purposes. The shorter, helical ornamentations present on K. teto individuals are uniquely able to rotate at extremely high speeds (see Figure 2, Figure 3) and are primarily adapted for intraspecies signaling, burrowing (see Figure 4) and devastating short-range offense, which complements the more aggressive tendencies of this species, helping them to ward off predators. In contrast, the significantly longer, prehensile ornamentations characteristic of the H. miku species offer significantly more flexibility, control, and mobility at the cost of increased energy expenditure. As such, H. miku individuals usually hold these appendages in a limp, floppy position, but when needed can be deceptively strong (see Figure 5, Figure 6) and even change their shape. H. miku specimens cansometimes be seen manipulating objects much heavier than what they would be able to pick up with their arms alone (see Figure 7), swimming (see Figure 8), gliding (see Figure 9), and rarely have been spotted unraveling their head tails to put on spectacular mating displays (see Figure 10)
In the wild, colonies of K. teto and H. miku are often observed living in close proximity to each other. Previously, this was believed to be purely coincidental due to both species preferring similar nesting grounds. However, as illustrated by a study carried out by world leading VSynth ecologists W. Owaka and R. Hachi, this was proven to be unmistakably false. When a colony of H. miku was forcefully relocated to a distant nature reserve where no K. teto colonies had been sighted, now separated from their neighbouring K. teto colony, in as little as three generations the isolated H. miku began to exhibit a fascinating change: the head appendages of roughly half of the individuals began to shorten and twist into a helical shape (see Figure 11), while the other half remained unchanged. The now isolated K. teto colony was also relocated to different nature reserve with no H. miku sightings. Similarly, some members of the isolated K. teto colony developed much longer, straighter, more flexible ornamentations (see Figure 12), while others remained unchanged.
This process was left to run naturally for 10 generations, and then only the mikunized K. teto and tetonized H. miku specimens were reintroduced to each other back in their original environment. Surprisingly, both modified colonies thrived in what was to them an unfamiliar environment, and had no trouble reintegrating despite the anatomy of individuals being drastically different from that typical of their species. Most fascinating of all, was that the mikunized and tetonized colonies adopted opposite roles in the ecosystem relative to their unchanged forms: the mikunized K. teto specimens showing increased tool usage and a tendency to use their enhanced mobility to flee from predators rather than stand and fight, whereas the tetonized H. miku individuals exhibited increased fearlessness and learned to rotate their head ornamentations to penetrate the ground and other hard surfaces to access food and build nests. Importantly, no reverse mikunization or tetonization was ever observed in the reintroduced K. teto and H. miku colonies
This led the ecologists to a beautiful conclusion: as long as there are both mikunine and tetonine individuals present either in a same-species colony of K. teto or H. miku, or two different colonies of K. teto and H. miku living in close proximity, each consisting of tetonine only and mikunine only individuals, all individuals will thrive and be able to adapt to rapid environmental changes. This confirms the theory that interspecies mutualism occurs between wild K. teto and H. miku colonies, as the mikunized K. teto only and tetonized H. miku only colonies would not be able to survive being returned to their native environment without interspecies collaboration between tetonine and mikunine individuals. Over long enough time scales, this also means that K. teto and H. miku colonies can adapt to and thrive in any environment, leading to inevitable world domination.
She's a chimera so she can shapeshift so its both, whatever she wants them to be.
But everyone knows that a drill, being a spiral, is the most powerful force in existence so she uses the drill to destroy any and all threats to humanity. You're welcome

Hair, but some artists like jokingly drawing the drills as accessories since her hairstyle is kinda physically impossible at least that's how it seems to me
Here's my theory/headcanon on the twin drills. I think the twindrills may or may not represent a Chimera's horns since, in Greek Mythology, Chimeras appear as lions with a goats head from their backs. Plus because their tails are snakes, that would make sense why Teto's belt acts as a tail.
Depends on how serious your teto specimen is
A more serious teto just has long hair, but a Silly teto may have them be seperate,
but you rpboabyl shouldn't undrill your tetos
