thinks of a way to defeat a person based on scents

“H552M. That’s got to be it!!”
When Kamijou reached for the heavy machinegun sticking out of the cargo door, the
professional gunner quickly grabbed him.
“Tell me how to shoot!!”
“Maya isn’t reliant on her Censer drones right now,” warned Luca. “She can’t be defeated
by physical attacks!!”
“That doesn’t matter! Listen, I’m going to start firing with this!!”
It was a lot like a three-legged race. Without a lifeline, Kamijou could be thrown outside
if the helicopter tilted and he worked with the gunner to forcibly aim at the flat wall of a
building up ahead.
Each shot was a huge bullet the same size as from an anti-materiel rifle. It was a poorly
aimed stream of bullets, but each one opened a fist sized hole in the wall, cracks spread
from those, those cracks connected, and the entire wall peeled away. It may have been
similar to piercing a window with an icepick to create a triangular hole.
But none of it actually hit Maya’s giant form.
“Don’t think your tricks can stop our feelings for Kamisato-kun!!” roared the ghost girl.
“!!”
Fran manipulated the screen of the card-sized terminal she pulled from her backpack.
Her UFO balloon had been floating around somewhere, but now she sent it toward the
ghost girl. Pirate Girl Luca’s spare bombs had been attached to it, but even that failed.
Maya swung her arm and they only blew away the wall of a nearby building.
The ghost girl with long black hair and white burial clothes was entirely unfazed. To target
the helicopter down by the ground, she swung her foot back like she was about to kick a
soccer ball. She built up enough strength to break a landmark broadcast tower.
“What do we do!?” shouted the gunner.
“It’s already over.”
The immediate reply was the one everyone had wanted but that no one had expected. Fran
and Luca gasped right along with the gunner.
“Maya was careful about what she ate to maintain just the right scent. I don’t know what
the exact ratio was, but messing it up is easy. When I was talking with the chemistry club,
they said there are basic smells just like there are primary colors. Use them and you can
overpower other, more sensitive smells.”
Henning’s theory had 6: Spicy, Flowery, Resinous, Fruity, Foul, and Burnt.
Amoore’s theory had 7: Camphoraceous, Musky, Floral, Pepperminty, Ethereal (as a
chemical), Pungent, and Putrid.
Unlike sight or taste, the classification was not complete, but that showed just how
complex a sense it was. For example, some neurophysiologists who researched smell
rejected the very idea of basic smells and – with two exceptions – it was not known why
humans detected those scents at all.
“That helped when we had no water during the heat wave. It was a luxury though, so when
we didn’t have any, we had to search out used coffee filters and teabags.”
This was Kamijou Touma’s goal.
“I targeted a windowless agricultural building where crops are grown. And with an H for
herbs and an M for mint!! The entire building is full of mint. Even if it’s all shriveled up
with the power out, blowing holes in the wall should release a dense aroma. And once you
breathe that in through your mouth or nose, you’ll lose that incense created from the
optimal balance!!”
It was unclear if ghosts really existed, but Maya did at least. By inducing psychological
instability with low-frequency waves and smells undetectable by human senses, she
created an environment where she could be seen and thus exist. It was a lot like passing
colorless light through a prism, so she could create the color or form that she wanted. And
that had transformed the slender and ethereal girl into a nearly undefeatable force.
“What…?”
But what happened when that fell apart? What if someone took a hammer to the prism
that split the light? Not even she would know how the light would scatter.
Goryou Maya’s beautiful face swelled out unnaturally.
The building-sized vengeful spirit could no longer maintain her own form. Her outlines
collapsed one after another, like her own bones were consuming her flesh.
“Kaaami…sssa…”
If she had come to a stop and calmed down, she might have been able to regain her form.
But.
Even if she had died and lost her physical body, she was still a girl in love.
“I will…do anything…for him!!!!”
There was no way she would stop. She stayed true to herself to the end.
Even as she crumbled away, she tried to kick at the road like there was a soccer ball there.
She did not give in. She would not hand Kamisato Kakeru’s fate to anyone she did not
approve of. None of them was a villain, but they had all chosen the wrong method.
Kamijou leaned out of the helicopter and clenched his right fist without thinking.
He considered jumping out at her if she continued pursuing them.
But she could not keep it up. By attacking as she fell apart, she ended up detaching her
own foot. The giant leg flew in a parabolic arc like someone throwing their shoe after
picking up speed on a swing.
