Unable to Persist for More Than Ten Seconds

Two blades appeared between Brooks' fingers. Thing as a cicada's wings, the hiltless blade twirled nimbly around his fingers, instantly dazzling the eyes of a large portion of viewers.

Knife set blades were the absolute most difficult daggers in the world to play with and were classified as creations of the Brooks clan. A few people would try to learn how to use this weapon, but after trying it out they ended up with various kinds of injuries and self-mutilations. Some even ended up with their fingers cut off.

The Brooks clan had a set of training methods secretly passed on that taught one how to use the knife set. This was obviously the clan's absolute secret and wasn't transmitted to outsiders.

Emily also didn't imagine she'd be able to see All-Mouthy King's battle the first week they paused their training. She was the most 'senior' of All-Mouthy King fans.
