The Strongest Ninja Sword Ninja Gekiatsuto (最強忍刀 忍者激熱刀 Saikyō Shinobigatana Ninja Gekiatsutō, Strongest Ninja Sword Ninja Intense Heat Sword) is StarNinger's variant of the Ninja Ichibantou. This weapon is used to evolve StarNinger into his Super StarNinger form as well as use Nin Shuriken for Advanced Shuriken Ninpo attacks.
The Gekiatsuto was originally the cursed demon sword Urasame, which would curse the user into becoming a Yokai and uses its power to deliver very strong blows. However, Kinji was able to change Urasame by his own will to remove the Yokai's despair curse inside Urasame, enabling him to become Super StarNinger with each use thereafter.
However, despite this sword is officially in possession of Kinji, Kinji mostly lend this sword to Ninningers instead of using it by his own and rarely powering up himself with the sword in latter episodes.
To be added
The Gekiatsuto's signature finishing attacks are the Gekiatsu Winning Super Star (激熱ウイニングスーパースター Gekiatsu Uiningu Sūpā Sutā) and the Gekiatsu Lightning Super Star (激熱ライトニングスーパースター Gekiatsu Raitoningu Sūpā Sutā).
