These Demon Realm mushrooms have a remarkable ability to survive. Many can be found in damp forests and caves, yet these startling mushrooms that stand erect with a masculine appearance can even be found in harsh environments such as desert and volcanic regions, and frozen tundra. The part that looks like blue veins rising from the surface of the mushroom is something that formed because of the Demonic mana flowing through there. It is supposed that the more blue veins there are, the higher the quality of the raging mushroom. It has a spicy taste, which is unusual for a Demon Realm food, and it's used to accent a dish. According to the monsters of Zipangu, it goes very well with their staple food, which is white rice.
Basically, monsters have vastly superior physical abilities than humans. Unless a person is a thoroughly trained warrior or hero, they won't be able to beat a monster in a simple test of strength. This mushroom has the shocking power to reverse the status-quo. But it's not as if a human man who eats this mushroom will be able to obtain the freakish strength of a dragon just like that. To be more accurate, it causes the mana naturally released from a man's body to have the quality of severely weakening a monster's physical strength. Because of this, even a frail, scrawny, sickly, whelp of a man can appear to boast freakish strength and defeat Dragons and Minotaurs in a contest of strength.
However, it's not as if it can affect any given monster. Because the mana works in a peculiar way to exhibit the effect, unless a monster intentionally accepts it, it won't be effective. In other words, if the monster being dealt with was the wife of the man who ate it to begin with, or if the monster had intended to attack the man, or if the monster felt ready for sex. That is it's only effective on monsters that are prepared to receive a man's mana, and it's completely ineffective on others such as those who have their heart set on someone else, those who have a husband, and those with no interest in that particular man whatsoever.
Be that as it may, unmarried monsters will generally attack to copulate with men, so this mushroom should be effective against most available monsters. For that reason, there was a military unit in The Order of the Chief God that noticed the effect, and tried to use it to vanquish monsters. However, this mushroom has another effect which causes men to become violently passionate and lose their rational mind, filling their head with nothing but plenty of thoughts of mating with the female in front of them, effectively making them like an aroused male beast. Thanks to that, it can't be used in combat, and it is said that the soldiers of the order that headed off to vanquish monsters turned the tables on monsters that attacked and tried to rape them, raping them instead, and thus, they definitely became their husbands.
If a man eats this mushroom, he can turn the tables on any kind of monster that attacks him, pushing her over with what appears to be overwhelmingly superior physical strength and unilaterally raping her. Also, when men eat it, it also has the effect of exciting the penis more than usual, causing their erections to tower with great size and thickness. No matter how ferocious and sadistic she may be, a monster raped with such a penis will learn the joy of being violated as a female and raped by a male of overwhelming power, and she will develop a masochistic disposition and desire to be raped. In fact, I yearn for this a bit myself.
Once she's been treated like this, a monster won't be able to forget it, and she'll become enthralled with being violated by her stud. For that reason, it appears that huge amounts of these mushrooms are bought up by such monsters all at once.
Additionally, if a monster eats this mushroom, her ferocity will remarkably increase, and she'll become a sex crazed beast and attack a man. Even timid monsters like “Cockatrice” and innocent monsters like “Alice” will intently attack and copulate with men like wild beasts, so it can be used to spice things up for a fresh sexual experience. Also, if a human man and a monster eat these mushrooms at the same time, it'll be like a clash of two beasts, but the monster won't be able to overpower the male due to her strength weakening, and the human man will definitely end up winning and violating the monster.
