Robin Hood

Robin Hood (ロビンフッド) is a magic-assisted ranged projectile weapon used by the Knights of England. Most notably used during the British Halloween, it is designed to eliminate targets by firing arrows guided by magic, although it also has the capacity to launch unorthodox targets.

Etymology
The weapon is named after Robin Hood, a heroic outlaw from English folklore.

Appearance
The projectiles shot by Robin Hood consist of a streamlined arrowhead on a pole about 30cm long.

Principles
Robin Hood is a long-distance sniping weapon, which possesses a fair amount of destructive power, enough to take a target's should it hit. The magical arrow is guided to its target by the knights' spells.

The weapon was developed for military purposes by a unit serving under Princess Carissa.

British Royal Family Arc
The Robin Hood spell is first mentioned by Laura Stuart during the Sky Bus 365 terrorist incident, intending to have the Knights of England use it against the terrorists in the event that Sky Bus 365 makes an emergency landing, as they have intended after manipulating the plane's fuel gauge. However, it wasn't used as Laura's plans fall through, and moreover, the plane landed safely and the terrorists were already beaten.

Robin Hood was used by the Knights in an attempt to silence Lessar after she was caught by Kamijou Touma and Oriana Thomson. Oriana recognized the weapon, leading her to realize the involvement of the knights. The knights also made use of it during the events of the coup d'état, which followed after Carissa obtained the Curtana Original.

Magic God Othinus Arc
The weapon was used by the knights to shoot Loki (or rather his illusory body) on Carissa's command during the attack on the Sargasso in the North Sea.
