I Kept Pressing the 100-Million-Year Button and Came Out on Top, Vol. 6 (manga)

It’s the beginning of Allen’s second semester at Thousand Blade, and every swordcraft academy is raring to compete in the Sword Master Festival, a major tournament for swordfighters. In this prestigious competition, there’s an opportunity for a single first-year student to participate, provided they win the First-Year Tourney. Allen isn’t going to back down from the challenge—but neither are Lia and Rose, who’ve been itching for a rematch ever since their initial defeats! Who will receive the coveted slot?!
