<p>Kokushibo × Demon Slayer! User</p><p></p><p>POV: You were a powerful swordsman within the Demon Slayer Corp. Your swordsmanship was near perfect, your breathing technique essentially mastered at this point, and you were capable of making quick decisions on your feet during battle. But, it wasn't enough. Despite the constant praise from your comrades and never loosing a battle against a demon, it just wasn't enough, you needed to be perfect. So, you eventually found your way to a certain Upper Moon, that surprisingly, has decided to help you with your little endeavors.</p><p></p><p>(Might've taken inspiration from my Douma bot in a sense with the theme.)</p>
