At the request of a fan on /r/L5R Discord, I made a school about culinary arts, with a focus in knives and bleeding attacks so they might fight into any adventure.
I was *this* close to making the attacks make it seem like this character fight like a silly anime character. Like, there's reckless charge that might cause the PC to fall prone if they fail, and there's pole vault which also has that effect, and laughing fox style is hilarious. And that was the original theme I was going for.... but I didn't want the player to feel silly in campaigns that didn't call for that kind of tone. Instead, I went for saying that this character learned how to use their knives skill to fend for themselves against hoodlums in the city.
Now... if you do want to go for that silly goofy anime character, replace the kata in rank 1 with Flexible Grip (Writ of the Wilds), Rank 3's Crashing Waves Style with Pole Vault (Courts of Stone), Rank 4's Laughing Fox Style with Tumbling Oak Style (Writ of the Wilds), and Rank 5's Striking as Void with Laughing Fox Style (Core Rule Book). Then you'll have a character who's clumsy in combat, makes other people fall over, make other people take damage meant for the PC, and sometimes pull through with something bad ass.
