Description
Oh, Takarajima! Golden sunburst! Draw your sword! Avast - take aim! Yohoken Taiyo! Taiyo rising! The light reflecting from the golden gunblade shows where riches lie!
Real name Chinami Myoushin, Cutlass was the chosen wielder of the sacred sword of the sun, Yōhōken Taiyō (陽砲剣 帯陽, "Sun cannon sword band of sun"). However, she defected from the ranks of the Swords of Logos, abandoning them to become a feared pirate queen; while she still fights the Megiddo when people need to be protected, she answers to nobody and will take whatever she thinks she deserves as payment.
Following a battle with her fellow swordsmen when she fled the Swords of Logos's base, her Wonder Ride Book Oh! Takarajima ("The story of a certain pirate king and the treasure he left behind.") has been damaged, a black spot marring its Story Page; her other book, Robin's Wood, was left behind when she defected. As a result, the leg armor of her Kamen Rider form does not form properly, weakening her and forcing her to rely on her wits and trickery to escape the pursuit of her former comrades.
As with the similar Sword of Sound Suzune, Yōhōken Taiyō can switch between two modes: the Flint Lock gun form and the Flint Steel sword. Its finisher is the direction-reading strike ("hōkōdoku geki"), which manifests as the Bullets of Eight ("yattsu no danpen") or Gold Sun Sand Triple Slash ("kane san sando sanbai zan") depending on its form.
So, obviously, Cutlass is a retool of Slash, in the vein of Falchion being based on Saber; "Oh! Takarajima" is Robert Louis Stevenson's Treasure Island. Her visor was primarily based on a compass rose, but I also wanted it to look like a sun, a gold coin, and the muzzle flash of a gun. While I came up with her before Saikou debuted, I was already fairly confident that a swordsman of light was going to be introduced, so I decided to make her elemental motif sunlight specifically. I admit that I was delighted when I realised that "sun cannon sword" could be written as "yo-ho ken"; originally the sword's name was "Nettaiyo" before it was pointed out to me that the second halves of the names were all two kanji each.
