Kotetsu

Kotetsu manifests as a youthful male with a quiet and hesitant demeanor.

His personality has been deeply shaped by years of unfair treatment at the hands of his wielder, Sunao Sumeragi.

This sense of being unwanted and mistreated mirrors the initial struggles of Kazuya Kagami.

The Match and Destruction

During a battle between Kazuya and Sunao, Kotetsu suffered severe damage because Sunao's aggressive fighting style caused his accumulated injuries to worsen.

The finishing blow came when Kazuya activated his "Divine Possession," and his empowered weapon shattered Kotetsu's hilt completely.

Trauma and Disappearance

Kotetsu was sent off for repairs, but the unreasonable cruelty he had endured from Sunao left deep emotional scars.

Even after his physical restoration was complete, he was too terrified to take human form again.

He believed he was worthless, thinking, "I couldn't save Sunao, and I couldn't be of any use to them."

His greatest fear became the rejection he was certain would follow.

Reconciliation and Return

Everything changed when Sunao apologized sincerely to Kotetsu from the heart.

By directly conveying a genuine desire to stay by his side, Sunao broke through the barrier of Kotetsu's trauma.

Hearing this heartfelt wish allowed Kotetsu to overcome his fear and regain the ability to assume his human shape once more.
