Saikyou Kensei no Mahou Shugyou: Level 99 no Status wo Tamotta Mama Level 1 kara Yarinaosu

Once, there was a legendary swordsman known as Raguna, the strongest of his time. He ventured alone into the mysterious Tower of Heaven, a dungeon no human had ever fully conquered. Pushing his limits, he reached the seventh floor—but there, his growth stalled at level 99. Refusing to accept defeat, he chose to reincarnate, keeping his formidable level 99 strength while starting anew from level one. This time, armed with even greater magic and powerful allies, he sets out to conquer the tower once and for all.
