The older brother of the Oros siblings thrusts three darts forward with a wide grin, declaring their power. The ability of the Oros siblings is triggered when the badge made out of Nen is attached to the body of the target. At this point, the target's body is linked to the dart body made out of Nen by the older brother, and until the game ends, the badge cannot be removed even by the siblings themselves. When the older brother's darts hit the target, the enemy receives the darts attack. There is no way to avoid the attack because until the dart hits the target's body, it does not exist at all. Thus, it is impossible to sense it or dodge it. This is our invincible power!! When it triggers, it's invincible!! However... Of course, they are taking a comparable risk!! The younger sister watches from below with a serious expression.
