The Kendo Swordmaster's Hundred Demon Cards

Reborn into a Tokyo plagued by grotesque evil spirits, Uesugi Kiyoshi was just a broke high schooler, his only hope for survival: self-taught Kendo. He battled minor demons with sheer grit, surviving by instinct and blade alone as the line between reality and nightmare blurred. Just when he thought his ordinary struggle would define him, his dormant 'Hundred Demons Night Parade' system ignited. Now, with a 'Mind's Eye' to pierce every illusion and 'Mirage' flowing through his veins, Kiyoshi's true destiny awakens: to collect ancient 'Hundred Stories Cards' from vanquished yokai, turning their power into his own. His first mission? Defend a bullied classmate. But as the thugs demanded more, they had no idea they were about to provoke a nascent Tokyo Swordmaster, a boy whose soul cards were primed to unleash monstrous retribution.
