Profile 8: Touya Kazemaru

Name: Touya Kazemaru

Affiliation: Tailed Beast Demon 7

Previous Affiliation: Demon Slayer Corps

Blood Demon Art:

Insect Mind - Touya has the terrifying ability to control and manipulate insects, turning them into deadly weapons and formidable allies in battle.

Techniques:

· Swarm Disaster: Touya summons a massive swarm of varying sizes and shapes of insects. These insects can overwhelm and disorient their opponents, biting and stinging them relentlessly. The sheer number and diversity of the swarm make it nearly impossible for enemies to defend against every attack.

· Insect Inverno: Touya creates fiery insects that spread rapidly. As they buzz around their target, they build up kinetic energy, eventually detonating in fiery explosions.

· Cocoon Shell: Touya generates a protective barrier from an intricate weave of silk threads his insect minions produce. This cocoon is incredibly tough and seems impenetrable, able to absorb significant damage before it starts to unravel.

· Carnivorous Monarch: Touya summons a gigantic, ravenous insect that can swallow its target whole. This monstrous creature is nearly indestructible from the outside and can dissolve anything it consumes within its acidic body.

Backstory: Touya Kazemaru was born into the prestigious Kazemaru lineage, a family for its long and storied history of fighting demons. From a young age, Touya learned the ways of the sword and the ancient techniques passed down through generations.

Unlike many of his ancestors, Touya did not possess a Breathing Technique, yet his natural abilities and combat prowess were so exceptional that he quickly rose through the ranks of the Demon Slayer Corps.

His agility, strength, and uncanny reflexes made him a force to be reckoned with, and it was widely believed that he would soon be officially recognised as one of the Hashira, the elite warriors of the Demon Slayer Corps.

However, Touya had no interest in titles or fame. For him, becoming a demon slayer was to protect his family, particularly his younger brother, Shuhei.

Touya's love for his family was the driving force behind his every action. He had taken it upon himself to bear the responsibility of protecting them, believing it was his duty as the eldest son. He had promised Shuhei that he would handle the world's dangers so his younger brother could live a peaceful life.

However, fate had other plans. Touya found himself facing the Tailed Beast Demon 7. The battle was fierce, and though Touya fought with everything he had, he was barely able to defeat the beast. Just as he believed the battle was over, the Upper Moon 3 demon suddenly appeared, turning the tide against him.

Wounded and exhausted, Touya realised he was outmatched. As the Upper Moon 3 toyed with him, the demon presented him with a cruel choice: die and leave his family vulnerable to the demons, or become one of them in the hope that he could protect them from within the darkness.

Torn between his duty as a demon slayer and his love for his family, Touya had to make an impossible decision. In his final moments as a human, Touya chose to become the very monster he had spent his life fighting.

He allowed the Upper Moon 3 to turn him into a demon, hoping that by doing so, he could find a way to keep his family safe from the horrors of the demon world. But in becoming a demon, Touya lost himself, his humanity slowly eroding as he took on the role of Tailed Beast Demon 7.

Though he retains fragments of his memories and his desire to protect his family, they are buried deep beneath the bloodlust and instincts of a demon. His hope that someone stronger would one day emerge to protect his family from him, and others like him is the last vestige of his humanity, a flicker of light in the overwhelming darkness that now consumes him.
