A Demonic Infection

"RUN!" A man shouted, swinging his sword to block a lightning-fast mushroom flying at his face.

The mushroom bullet deflected toward a tree, shattering several branches before flying to the sky. The swordsman could feel his arms tingle from the impact, but he stood still.

Tens of red, prolonged mushroom tentacles flew from the trees like whips, each shattering trees as they passed.

"It's a tentacle demon! Bring fire!" He shouted, deflecting each of the tentacles as the others behind him pointed their swords forward.

[Fire Wave] Their blades turned bright red, releasing a burst of flame and setting the bushes ablaze.

A sharp, ear-piercing cry burst from the woods, and a zombie-like man infested with mushrooms rushed out, burning as tentacles came out of his body.

The swordsman grunted, closing his eyes with a pained expression, "So you have fallen, Eren," He lunged forward, cutting the demon's head, "May you rest in peace."
