Standard Equipment:

  • Springfield XD (スプリングフィールドXD Supuringuhuīrudo XD): Rentaro is in possession of a, as he states, normal black gun.

He has shown great mastery over said weapon, shooting a Stage I Gastrea repeatedly without showing any signs of fatigue and with the ability to maintain his stability throughout the process.
  • Black Bullet (ブラック・ブレット Burakku Buretto): With his gun, Rentaro's main projectiles of choice are Black Bullets, which are created from the very same object that keeps Gastrea away from the Monoliths, Varanium. He himself states that with said bullets, Gastrea will not be able to recover; giving him the upper hand when in combat. These Black Bullets were able to harm a Stage I Gastrea greatly,[86] in contrast to when Tadashima attacked with regular bullets; to no effect.
  • AGV Experimental Drug (AGV 試験薬 Shiken Kusuri): Rentaro was given five needles by Sumire that contain AGV Experimental Drug within. He was told by Sumire herself that this Experimental Drug contains artificial Gastrea Virus that grants him superhuman healing abilities,[88] and is only to be utilized as a last resort weapon;[89] the user may forfeit their humanity.[90] When Rentaro injected himself with a needle in his abdomen, he releases a loud and vigorous roar that intimidate those around him.[91]
  • Superhuman Healing Capabilities: After injecting himself with a sole dose, Rentaro's wounds begin to heal instantaneously. Additionally, Black Bullets, previously shot by Kagetane, exit his body, with the wounds healing themselves and appearing unharmed; smoke arising and evaporating into the air. The speed at which the wounds can heal themselves appears to be rather swift, as a wound caused by a bullet heals in a mere amount of seconds.
  • Flashbang (閃光弾 Senkō-dan): When Rentaro places a Flashbang into effect, a bright light and disturbing sound to the ears surround the area around his opponent; rendering two of their senses ineffectual. This non-lethal weapon is additionally used as a form of diversion for future assaults.
