Yes, a Signauture Weapon from Ultraseven, also known as a Space Boomerang, it can also be detached and even can be used as a projectile, or even a melee weapon, it's also Seven's most well-known weapon if all of you Ultraman and Ultraseven fans know. The Ultra Series is owned Tsuburaya Productions by the way, and I DO NOT OWN THE ULTRA SERIES. Model from Asousa, NeoUltimo, JakkaeRont, and BigJohnnyCool.
