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.


New Generation

Miwa originally applied as an office worker, but was berated by the boss. As a result, she knocked him out after having enough of his words. She was handpicked, along with Shin Magaki (Kamen Rider Lance), by Shimura Junichi (Kamen Rider Glaive) to become the New Generation Riders for BOARD to capture the Undead released by the Albino Joker.

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.

Behind the scenes


Natsumi Miwa is portrayed by Yoko Mitsuya (三津谷 葉子 Mitsuya Yoko). As Kamen Rider Larc, her Suit Actor was Yuuki Ono (小野 友紀 Ono Yuuki).


  • She shares the same first name as Natsumi Hikari (Kamen Rider Kiva-la) from Kamen Rider Decade
  • Natsumi is the second official female Rider in the Kamen Rider Franchise.
    • Larc suffered the same fate as her Female Rider predecessors (Tackle & Femme) and died.
    • The Rouze Card she holds in her hand after her death is the 4 of Spades, Tackle Boar.
    • Ironically, her counterpart in Kamen Rider Decade, Haruka Miwa, survives the events of the World of Diend two-parter, in fact, all three of the Ace Riders in Decade survive while the originals in Missing Ace all died.
  • Larc's color scheme and use of a long-range weapon make her analogous to Garren, whereas Lance is analogous to Leangle and Glaive is analogous to Blade.
  • Sometimes, Natsumi's Rider alias is spelled as Lark (due to the kana used) or L'arc (due to her name coming from a French term).
    • "L'Arc" is French for "the bow".
