is one of the main protagonists of Kamen Rider Kabuto. The motif is that of a "Kuwagatamushi" or stag beetle. The name is a portmanteau of "kuwagata" and "attack"

is Gatack's user. Joining ZECT two years to kill the Worm that murdered his younger brother Ryou Kagami, whom he made promise him to work hard to become a pitcher, Kagami is a field agent of ZECT who also works with Hiyori at Bistro La Salle. He has a good heart but is hot blooded and will often act without thinking about the repercussions of his actions. When the Kabuto Zecter is completed, Kagami attempted to become Kabuto but the Zector chose Tendou as its user. Being the only member of his group to know Tendou's identity as Kabuto, Kagami supported him much to the dismay of his team. While finding the restaurant filled with Matsuwa addressed to him, Kagami meets Jyuka as she takes him to the Tendou residence. By the time he realized he's slacking off, Arata runs off as Jyuka has him promise to come back as she tells him he's the first friend Tendou made.

But on his way back to the Bistro La Salle, Kagami meets Ryou whom he set up a meeting with tomorrow. However, Tendou contacted Misaki of this and she came to the conclusion that the Ryou that Kagami met is actually a Worm. The next day, Kagami confronts Tendou about it, telling him he'll kill the Worm himself if it's true. However, once Ryou reveals himself as the Bellcricetus Worm, the Worm that had killed and mimicked his brother, Kagami could not bring himself to kill it as its death would erase all that remained of Ryou. As Kabuto arrives to save, he doesn't fight back against the Bellcricetus Worm until Kagami is forced to allow him to kill the Worm. Losing the chance to honor his vow, Kagami makes a new one to suprass Tendou as he receives Ryou's baseball from him.

Kagami was later chosen by the TheBee Zecter to become Kamen Rider TheBee after it rejected the previous user, Sou Yaguruma, and reacted to his desperation to protect the wounded Shadow members. Kagami, however, gave up his role as TheBee after he was torn between the orders of ZECT to eliminate Kabuto and his budding friendship towards Tendou.
