Tensei Coliseum — When ‘Useless’ Skills Become Deadly Weapons

About this series

Kouji’s ‘useless’ Copy skill turns into a nightmare for anyone who underestimates it. In a savage coliseum packed with fierce female fighters, raw power means nothing—smart combos and cold strategy decide who lives. Kouji isn’t here to be a hero; he’s exploiting system glitches and bending gender norms to build a ruthless harem empire. If you want isekai with sharp tactical battles, ninja moves, and a dark twist on fantasy, this one’s for you. Ready to see weak skills wreck the strongest foes? Kouji’s rewriting the rulebook with every brutal fight.
