This ancient weapon was once used by protectors of the realm, the so-called neon knights. The name comes from the fact that sword works on the principle of neon particles, which are at the core of all beings. The bearer of bracelets projects extremely sharp and deadly neon blade. Bracelets have self-regenerated energy tank, which is emptied when using. The sword can be used for attack or for defense, especially from solid projectiles.
