Well the manga seem to be on hiatus and no one seems to have not wanted me to continue my shitty fanfic erotica, so, ehem.
(I don't write much so I make no promises of quality coming anywhere close to "good" let alone "adequate".)
The mage corps brought the 'Flower that makes women disheveled' to the battle, hoping that the demon would be female enough for the lascivious plant. Most of the females who learned of the plant and the plan involving it looked at the mages in disgust but so be it, some sacrifices must be made! Some of the troops were even into the elves looking at them like that but the plan must come first, to get the plant after the tomboy demon and give the men a sho-. . . I mean to defeat the demon and win the day! The plan started once the Fire Demon King was far enough away that the Earth Demon King couldn't protect her, the mages brought up the flower, still in it's containment capsule the research division used to study and experiment on it 'safely', taking only enough time to tell all females to flee and then threw the capsule at the cute tomboy- I mean Fire Demon King.
So far so good, it broke open on her and spewed it's pollen. . . ONTO THE KNIGHTS AND MAGES! Everyone started panicking while feeling hotter and more sluggish, it would seem that they did not know that in their experiments they swapped the gender preference of the plant they brought. The flower immediately set to it's debauched work, tentacles slithering rapidly towards it's soon-to-be pray and coiling around them, dragging knights -kicking and screaming, aware of the fate awaiting them- along the ground ever closer. The mages, caught the pollen blast at the tail end due to distance, assumed they were safe to think of a plan. Until the first one cried out and disappeared, then another and another. The rest finally noticed, all too late, that they were not in fact safe as the flowers Lustful tentacles had plenty reach and numbers to bring them all together.
The hard part was finished, the flower had gotten it's new lovers and all that was left to do was remove the hinderance known as 'clothing' and then begins the fun part, fulfilling it's purpose in life, bringing men to a disheveled state. Safely of course, these flowers are gentle lovers after all.
The flower began it's meticulous work, getting the clothes off was part of the fun after all, sensually and erotically stripping the clothes off slowly adds to the experience.
It began with the knights, peeling the armor off plate by plate, the pollen was working well in getting them in the mood and unable to resist too much that they endanger themselves, the mages were excited, why else would they be moving and making so much noise? Another dose of pollen would stop their struggles soon enough. Back to the knights, their armor was removed but they still had some clothing on. For now. Slithering some of it's smaller tentacles in to the waist of their pants gave it plenty of room to slide off the pesky cloths, finally freeing their glistening muscles, drenched in sweat and musk, to the air and -more importantly- the flowers tendrils. But they must wait with their no doubt baited breath, for the mages have been neglected for far too long and need the flowers attention. No armor, good that makes things easier if it's just robes. The flower began to disrobe the mages in every sense of the word, they were no warriors, with muscles toned from years of hard work and effort but they had their own appeal, the erotic flowers do not discriminate after all. Once the mages tender, slender frames were born naked to the world, and the flower, finally it's attention went to the elves and their tight fitting but lacking clothes.
Not much was there to strip but the flower too care just like the others, hast would only serve to spoil the mood after all.

The females were shocked to say the least, these idiot males decided on this plan!? well it seemed to work up until the flower pollenated the males instead of the Demon King, in fact it seemed to be ignoring th. . . "WAIT THE DEMON KING MIGHT ATTACK WHILE WE'RE DISTRAC-ted?!" In response to the females question of what was going on with the Demon King she had turned from the usual 'Demon ash gray' a bright shade of red and was covering her eyes, taking glances at the flower ravishing the males occasionally of course, "well they reap what they sow so we may as well enjoy this for now."
As the flower went to town on the males, leaving none of them dissatisfied, the females -Demon King included- burned the whole event into their memory for later 'use', in fact a couple of them had already mostly hid around the corners of buildings or behind crates, rubble or any other debris to 'enjoy the show' as it were while still being able to watch.
After a while the flower seemed to finish it's task so when the Demon King started showing signs of getting over her maidenly bashfulness one of the female knights and mages came over to bop her over the head and cast sleep respectively. one P.O.W acquired and the flower mysteriously vanished, presumed dead by all females present according to the report later. This battle was over but no one would be forgetting it any time soon.
