|Nine Lives Breaker|
|Novel Debut||Chapter 98|
|Anime Debut||NEXT Episode 12|
The Nine Lives Breaker is a device in the Boku wa Tomodachi ga Sukunai series. It consists of multiple floating metal balls and a pair of cat ears. It is based on an attack used by Shenhua in a Kurogane no Necromancer video game.
As the name implies, the device is comprised of nine small metallic balls controllable via remote paired with a hair-crown designed with cat ears which react to the user's brain waves.
In the anime adaptation, Rika was shown using more than nine metal projectiles.
The user places a pair of fake toy cat-ears on their head; this is just a feint to trick the opponent into thinking the user controls the balls with them. Using a concealed remote, the user can control the numerous metal projectiles simultaneously to do their bidding, such as levitation or directing it to a certain target. As such, it can be used for intimidation or to inflict pain on others.
