One day, in the Adventurers' Guild of the labyrinth city Mace, two middle-aged men sipped drinks and chatted about recent gossip.

"Hey hey!! Have you heard?? The Sharkhead Gang all fled overnight!!??"

"Word is, a guy in black armor wiped them out completely!"

"Just one person??? Unbelievable!!"

"Get real! That’s the same guy who clashed with the legendary Dragon Deity in the labyrinth recently!"

"I know, I know!!! Rumor says two girls helped him as assistants too!!"

"Yeah, yeah!! But even they don’t know his real identity."

"A man who wipes out the Sharkhead Gang and stands up to the Dragon Deity? Terrifying!!! Seriously, he needs a name—what’s he called??"

"Dragon Warrior!!"

"Hold up!!! You totally made that up, right??"

"Uh... yeah, I did, but it fits!!"

"What’s his actual name!!!"

"No one knows!!! For now, everyone just calls him the Black Knight."

"That’s even cheesier... How about Night Knight instead?"

"That’s no good either!!!! What about Kamen Rider???"

"No way!! Let’s go with Black Swordsman??"

"That feels incomplete without a weapon!! How about Grim Reaper?"

"Nope, nope!!! It’s gotta be Zero!!"

"That’s wrong too!!! Fans of that other big-name character will beat us up!!!"

"Partner of Justice??"

"That’ll get us all wiped out!!!"

"Tuxedo Mask then?"

"Where’s the tuxedo?! What kind of nonsense is this!!!"

"Yuzuru..."

"Stop!!! Let’s just call him the Black Knight!!!!!"

Stories about a lone figure began spreading through every street corner—how he conquered the labyrinth, how he outwitted and battled the Dragon Deity, how he heroically rescued damsels. No one knew his true name or face, but all agreed on one title: the Black Knight.
