[Demon Slayer] I Got My Kill Stolen Again Today

Kakain Ranka, an ordinary Demon Slayer Corps member with the strength of a Hashira... Huh? You want to know why? The first time news came in about the Twelve Kizuki... Kasugai Crow: Sorry, the information was wrong. The second time news came in about the Twelve Kizuki... Kasugai Crow: Huh? The Insect Hashira passing by killed them. The third time, Ranka gripped her Nichirin Blade in both hands and stared excitedly at the arrogant Lower Rank Four in front of her, barely managing to keep the corners of her mouth from turning up... "Hey! You, don't hurt my little sister!" Her big brother, the Feather Hashira, swung his sword and killed the demon in an instant, then gave her a smile that said, "I'm amazing, aren't I?" "..." "Xia, don't go! Your Nichirin Blade!" Kakain Ranka's greatest wish is to take down her big brother, the Feather Hashira, and claim his position.
