With having L5R on the brain, I've been deep-diving into Japanese-inspired media and was curious about this weapon, used by the Corrupted Monk in the recent game Sekiro: Shadows Die Twice .

Is this a naginata? A bisento? A zanbato? My first instinct is a nagamaki, but I'm not sure if there's no rules for those. I only have the Corebook, though, so if it was introduced in one of the subsequent books, please let me know!
