Not Just Quirkless(BNHA X KNY Crossover FF)

Yoru Kazuya, a 15-year-old Demon Slayer or should I say Hashira. Since she was young she was bullied and even kidnapped once. Her Family was massacred by demons, but instead of seeking revenge she became a Demon Slayer when she was 8. She soon became the Hashira of Wrath.

80% of Humanity has what they call Quirks. The other 20% do not have this ability and are therefore classified as Quirkless. Less than 1% of that 20% are Demon Slayers. Overtime Heroes and Villains became the trend. In the world there are humans who roam during the day. Then there are Man-eating Demons who roam during the night. For that very reason, the Demon Slayer Corp was established to exterminate these Immortal creatures called Demons. They are respected and feared by both Heroes and Villains. Even All for One wouldn't mess with one. Despite being popular, the Demon Slayer Corp is hidden from society, therefore being called a myth.

Yoru Kazuya is one of these well respected Demon Slayers. She is the Hashira of Wrath, the strongest among the Hashira, who are the highest rank a Demon Slayer can get. She is loved by many in the Demon Slayer Corp. She is kind, too kind. She empathizes with demons and usually cries after killing one. She always remembers the name of the Demons she kills.

She decides she wants to join UA, Oyakata-Sama being her loving Father Figure asked his friend, Nezu. Nezu accepts knowing that Yoru is a Demon Slayer, just not her rank. She joins Class 1-A. How will they react when they find out the thing they thought was a myth is actually a reality? How will they react when they find out Yoru is a Hashira?
