Casey Jonas Williams, better known as Boomer, is a Heroine from Spiral Clicker, an indie dating sim from Changer. She is the Navy Commander of the Magic Kingdom.

== Appearance == Casey is 39 years old, stands at 5’11” (180cm), weighs a staggering 468lbs (212kg), and has 30E cup breasts; she isn’t obese, nor overweight. Her massive weight is due to her Magic Kingdom abilities (being able to float above the surface of water) giving her an incredibly large body density, which thus triples her weight from the standard 171bs (77kg).

When not using her abilities, Boomer weighs a far lighter 171lbs (77kg). This means that, whenever she’s using her powers, her weight triples, as a strange side-effect of her powers, which increases her body’s density by quite a bit, making her instantly sink if she were to be submerged in water. Hence a reason why she absolutely needs to use floaties, and even wears them alongside her black swimsuit specifically.

Boomer's main outfit, a striking contrast to her weaponry, is a Japanese-style school uniform, likely a variation of a seifuku. It features a long-sleeved top and a pleated skirt, both in a solid dark color (black or very dark blue). A blue bow is neatly tied at the collar. The most notable accessories are practical additions for her combat role: a set of brown or khaki harness straps are crossed over her chest, which are clearly used to secure the two large, green rocket launchers that are slung across her back. This combination creates a "schoolgirl with heavy weaponry" aesthetic.

Her underwear consists of a black bra and panties, both having red frilly details.

== Personality == Interestingly, Boomer never held any aggression at the one who bested her, at best displaying minor annoyance when she interrupted her doing weapon maintenance and their lowly status compared to what she might expect from someone capable to defeating her. Possibly out of gratitude as had she not been escorted to shore she could've sunk to the bottom of the ocean.

As her brainwashing proceeded, so to did any negativity to her conqueror, submitting fully to her new college life of learning her place within their harem and pleasing her Owner with dedication and being eager to please and do whatever is commanded, be it in a trance or wide awake.
