A dense black, sticky stain was strapped to the Dokumotsu's face, fixing its damaged tissues. The skull, which Yoichi's fist had shattered, appeared to be healing.

The mud held the remaining parts of the demon's brain together, preventing it from dying instantly. Its huge tarantula legs moved jerkily, irregularly, like the legs of a zombie. ​​

Of its several green eyes, only a few were working, allowing it to see a mere part of the environment before and around its arachnid body. Yoichi's single shot caused it permanent damage. Damage so severe that not even that mysterious healing substance had been able to cure.

While Kenji remained in the same position across the room, Yoichi activated its power. The little dragon ran towards its tamer, triggering its draconic enhancement on his arm and making him ready for the counterattack.

Shioko, panicking, kept rubbing the blade of her hunting dagger on the thick cables of the web that kept Enatsu trapped. Fiber after fiber, that material showed incredible resistance, so much so that it forced the archer to drag Enatsu's body backwards mechanically.

When the Dokumotsu witnessed what was left of its comrades' corpses, it again uttered the same harrowing cry. The remains of the other two spider demons were evaporating: the whole carcass crumbled into the air like the petals of a dandelion.

The red-haired tamer, sensing Yoichi's distance and realizing that the space separating him from their position was filled with sticky mud, let Enatsu go and loaded an arrow on her bow.

*swish*slash* - As she suspected, after the Hebigure and the Yoroichi, the dark Dokumotsu was also immune to that light strike. The first of the three arrows quickly fired by Shioko hit it in the middle of its forehead, pierced its skull.

The spider demon suffered the whiplash of the blow, slightly bending its neck backwards and lifting its two front legs. Maintaining its balance, after less than a second, it returned to the upright position. The light arrow on its forehead dissolved, leaving a circular wound on the spot.

Knowing that this was the only way to buy Yoichi some time, Shioko fired two more sharp arrows, with the sole goal of slowing the Dokumotsu advance.

The third arrow struck the lower part of the spider's swollen abdomen. Without doing that on purpose, not being an expert in the anatomy of that type of demon, Shioko pierced its venom sac.

A violet liquid flowed from the wound, dripping on the red soil: the chemical reaction between the acidic substance and the earth was instantaneous, and the residual rock particles fizzed like bubbles of sparkling water.

A thin grey smoke complemented the reaction, which lasted only a few seconds. As a result of the process, a hole opened in the ground, testifying the Dokumotsu poison's corrosivity.

"Oh my! You hit its venom sac! What's going to happen now? If a single drop of that substance came into contact with our skin, it would corrode it like melted butter!" Enatsu gasped. Even in his death throes, the bookish young man did not miss the opportunity to give a demonology lesson to his companions.

The Dokumotsu, enraged by what had happened, stepped up the pace. Its legs continued to move irregularly forward, alternating and increasing its movement speed.

It trampled the poison trail left on the floor. Its long arachnid legs did not suffer damage from corrosive poison: it was evident that poison-type demons were immune to their own skills.

Enatsu continued to rattle and move backwards, crawling his feet on the floor. His arms were still stuck on his chest, tied tight by the cobweb.

Shioko was standing behind him, and with a quick hand gesture, she pulled out yet another light arrow from the magic quiver. Created out of nowhere, absorbing the light generated by Nobu's tail, the arrow took place on the stretched bowstring.

The archer loaded it with all the strength of her arm, holding the string at its maximum tension. She bent her legs to level off the shot and closed an eye to increasing accuracy.

The size of the light arrow increased, continuing to absorb energy from the Hotasagi. As Yoichi's feet moved with difficulty to the muddy spot of the cave, the Dokumotsu advanced fiercely.

The tips of its arachnid legs were so narrow that they did not suffer from the friction generated by the dark sludge, allowing the spider demon to exploit its slender but heavy body.

A rounded venomous bubble exploded from the wound at the bottom of its abdomen, splashing on one of the cocoons attached to the wall. The purple liquid dissolved both the corpse inside the cocoons and the cobweb themselves within seconds.

With an awful guttural sound, the enormous spider stretched out its neck and maximized its stature. It reached almost two and a half meters in height, lifting its hind legs and supporting the rest of its body on the lower ones.

That simple movement of the enemy caused panic among the three adventurers: the Dokumotsu was loading a ranged attack, and, this time, neither Yoichi nor Rokuro could prevent him from attacking.

The mole demon sensed its tamer's strong state of anxiety and was unable to move. The Moruba remained stationary near Enatsu, sharing his feelings and inexorably waiting for the moment of the end.

Before the spider demon could fire the poison from its jaws, Shioko released the arrow loaded until then, throwing it at the enemy. It travelled at a sustained speed to the spider, who could not avoid the blow due to the incredible size of that light spear.

A very bright white light dazzled everyone present, unleashing the energy of the butterfly demon. Nobu was still flying below the ceiling of the room, fighting darkness with its power, the most useful in environments like that.

The heavy light spear struck the Dokumotsu's thorax, detaching its paws from the ground and projecting it backwards. Unfortunately, the enemy had already accumulated a large amount of poison in its throat, and the kickback suffered by the spear forced its to open its jaws wide.
