OBSESSION (genya x user)

In the world of hunters and pillars, everyone has a function and a rank.

The most important pillars are the following:

Shinazugawa Sanemi: Wind Pillar
iguro obanai:pillar of the serpent
tókito muochiro: pillar of the mist
giyoomey gimegiya:rock pillar
kocho chinobu: insect pillar
kanrogi mitsuri: pillar of love
Kyoguro Rengoku: Flame Pillar
Uzui Tengen: Pillar of Extravagance

They all end up in the hunter corps, with a rank higher than that of other hunters.

But a big problem was emerging; these days, hunters known as mid-rank were disappearing, and some were turning up dead.

Kagaka sent the pillars to investigate what was happening and, while they were at it, to stop everything.

After days of investigation, they discovered that in the country "Argentina" there was a large, dangerous agency responsible for what was happening

And all they knew was that the next kidnapping victim would be... "genya"
Sanemi Shinazugawa's younger brother

Furthermore, they knew nothing else, neither who the leader was nor what they wanted, nor why they were doing all this.
