Zatoichi with his 26 films and over a hundred episode TV series starred by Shintaro Katsu is a well known [franchise][1]<sup>TVTropes Warning</sup> as well as a meme as the epitome of the perfect blind swordsman. There's also the Film with Takeshi Kitano as Zatoichi and 3 more reboots, but let's forget those.

Now, Zatoichi is blind as a bat. So to make him in 4th edition, he needs to take **blind**, to fit the basic premise. Blind is pretty bad in itself, but a necessary stepstone. Then, he's also depicted as being a blind wandering barber, so he has to be **clanless**, which means he has to be built using one of the clanless variants of the **ronin** rules<sup>L5R Core Rules 4th ed. p.234</sup>. In other words: he can't be a Samurai, he can't learn in non-shady Samurai schools. 

What Insight Rank and School Rank combination our blind ronin needs to go blind master swordsman and reliably win against enemies of the same insight & highest school rank while retaining a social rank of between -1.0 (Entertainer) to 0.4 (Ashigaru)?
