This article is about a/an rider in Kamen Rider Blade.

For the A. R. World version, see Haruka Miwa.

Natsumi Miwa (三輪 夏美) was Kamen Rider Larc (仮面ライダーラルク Kamen Raidā Raruku, Masked Rider Larc), a Rider who appeared exclusively in Kamen Rider Blade: Missing Ace as a member of BOARD.


New Generation

During an office job, Natsumi Miwa is refused a promotion by her boss and resigns. Later, while out walking, Natsumi is attacked by the Peacock Undead. Meanwhile, a mysterious figure watches the assault and starts to approach her. Later Shin Magaki bumps into a fleeing Natsumi, and both start running from the Undead. Natsumi and Shin continue running from the Undead.

Natsumi finds a steel pipe and tries to get Shin to cover her escape claiming that men are supposed to protect women. This fails and the Undead continues chasing them until an explosion destroys it. The mysterious figure approaches them, no longer hiding and throws them both Change Kerberos Rouse Cards. He then returns back to human form.

Junichi offers them both to be Kamen Riders. He also explains that the incident with the Undead ended once, but the power of the Kamen Riders is needed again. Natsumi and Shin refuse and give back the cards. Junichi says to himself that they will return, and that it is their fate is to become Riders. Behind Junichi is Kazuma Kenzaki, who becomes a garbageman. Natsumi and Shin walk away, with images of their Rider forms being shown.

Missing Ace

Natsumi's death

In the movie, she is the replacement of Kamen Rider Chalice for the team's long range fighter, she is armed with the L'arc Rouzer, a crossbow. Her weapon is based on the Garren Rouser and the Chalice Arrow. Her primary finisher is Ray Bullet, a supercharged energy arrow. Upon Kenzaki and Mutsuki regaining their respective belts as Blade and Leangle, Miwa and Magaki have grown jealous against them. Attempting to gain more power, obtains the King Category Club card from the dying Shin Magaki, and later she steals the remaining King Category cards from Junichi, until she was killed by the Albino Joker, who is actually Junichi Shimura in shadow, leaving the Four card in her hand.

After his death. Kotaro reveals to everyone that Junichi himself is the Albino Joker as both of his victims Natsumi and Shin hold the cards 4 and Jack (both of which are a pun of his name (i.e. "Jack" and "Shi")).
