Huh!? Why can't I take off this armor!?
Damn! Damn! Oh, my head came off.....
(Dullahan that had been a human knight until only a moment ago.)

In the dungeons where monsters lurk, there sleep various treasures such as valuable, beautiful ornaments, and magically enchanted armors and robes, etc. Even among such treasures, there exists some equipment such as clothing, weapons, and ornaments, etc. that is imbued with powerfully concentrated mamono mana.

This equipment is also called “cursed equipment” by humans. Once a human puts it on, they're unable to take it off, and the thick, solidified mamono mana dwelling within the equipment will flow into the human wearer's body to bind with the mana inside. At first, effects such as a heightened mood, and greater physical abilities, appear. Depending on what race the imbued mana belongs to, it can cause various other effects such as improved agility and a better sense of smell in the case of “werewolf mana”, freakish strength in the case of “ogre mana”, and the ability to cast ice magic in the case of “yuki onna mana”. However, if worn for a long time, with each use of the equipment's ability, more mamono mana flows inside. It's difficult to notice because there will be no change in appearance whatsoever, but bit by bit their thoughts and behavior will get closer and closer to that of a monster of that race. Additionally, like a monster, they'll start to feel that human men are delicious, and notice the sweet smell of mana in the air.

By the time they notice, it's already too late, and they're unable to remove the equipment. Their desire for men just keeps on swelling, and all they can do is wait until they change into a monster. Eventually, all of the equipment's mana flows into the wearer, and at that moment, the body suddenly starts changing completely into a monster. Equipment like this has been set up as a trap for humans by the monsters of the “radical faction”. Monster merchants disguised as humans sell them to people, and they get mixed in with the regular merchandise, so they're scattered throughout all the lands of the world.

These items are made with a special product of the mamono realm called “mamono realm silver”, a metal that is easily infused with mamono mana. Other than that, if items related to each particular race are used, such as collars for “werewolves”, armor for “dullahans”, or flower decorations for “alraune”, then it's easier to infuse mana. What's dangerous are pajamas made from “weresheep” wool, etc. Only a faint amount of mamono mana dwells in wool that has just been sheared normally, and it would have no influence on humans other than causing the original effect of peaceful sleep, but it's impossible to tell if there's one with condensed mamono mana mixed just by looking. If a woman were to wear it and go to sleep, then upon awakening, she would completely change into a weresheep.

Additionally, if a man were to wear one of these items, then he would gradually change into an incubus due to the mamono mana imbued in the item. In that scenario, what's different from changing into an incubus normally is that the mana generated by the man will change to be more preferred by monsters of the same race as the monster whose mana is imbued in the equipment. For example, in the case of equipment imbued with “werewolf” mana, the flavor and taste of the man's mana will change to suit the preference of werewolves. The scent would tickle the nose of werewolves and be more appealing to them compared to that of normal mana. No matter where the wearer went, he would be hunted by unmarried werewolves, and he'd end up getting attacked over and over.
