Yuiitsu Muni no Saikyou Makenshi ~Oredake Norowareta Buki de Musou Suru~

Every awakener has their own unique [awakened-gear]. But Touya doesn't have his own [awakened-gear] despite being an awakener. Because of that, people call him [weaponless] and incompetent.

While working gathering mana stones, his team is attacked and killed. During the fiasco, a crest suddenly appears on his hand before he finds himself transferred into a room where a cursed [awakened-gear] (Dainsleif) awaits him.

Responding to the call of the sword, Touya gains ultimate power. With his new power, he slashes through his old problems and the people who mocked him. He set his eyes on what no human has yet accomplished, conquering the tower.
