Aarb Gear (アーブギア Ābu Gia?) is a set of armor created by the Aarb people for Ultraman Hikari to become Hunter Knight Tsurugi. Initially, it was called the Avenging Armor (復讐の鎧 Fukushū no Yoroi?) before Hikari used it properly in his righteous heart, becoming Hero's Armor (勇者の鎧 Yūsha no Yoroi?). The armor grants the user additional weight to 3,000 t, being the lightest armor.
