[X] An even more ancient chokuto, a straight-bladed sword, with a beautiful sapphire set in its hilt. This weapon hums with elemental power, the power of the storm. This weapon was said to be the legendary sword of a warrior kami of lightning. (Take this weapon if you want Kinjo's battles to be less grounded, more overtly magical - and to strengthen the roles of the gods and kami in the story).
[X] A naginata with an elegant crescent blade, black calligraphy marking the blade with the character for "Silver." This blade is said to bear the spirit of a female warrior of old, and it rises to the occasion of martial challenges, granting power to its wielder in proportion to their courage and skill. (Take this weapon if you want to introduce subplots involving martial arts and highlight Kinjo's martial skills against the decadent Tokugawa samurai mainstream).
[X] A Western firearm of advanced make, a pistol that can fire many shots with remarkable accuracy and power. The gun has some sort of blessing laid upon it by its makers and the Office has experimented with specialized ammunition for different yokai. (Take this weapon if you want to increase Kinjo's connections with Westerners and want them to play a larger role in the story).
[X] An old katana, stained red with blood. This demonic blade nearly vibrates in your hand with eagerness for battle, in the hopes of being able to devour the blood and lives of its foes. The raw power of this blade cannot be matched, but it is always a test of wills to tame and channel its essence. (Take this weapon if you wish to have a complicated relationship with the youkai you fight - you have a weapon of unparalleled violent power, but is violence the best way to solve situations?)
