what's in a name?

I have been named. Niina-gosoke has given most of the instructors proper 'iai' names (his is of course Niina Gyokusui Toyoaki; no idea what his "real" name is.)
My name is Kuroda Renjosai Yonekuni

Kuroda is of course my last name ("Blackfield")
Ren is also my name, written as I tend to write it with the character 'hasu' (lotus flower, traditional Zen Buddhist symbolism, Buddha is often shown seated on a lotus blossom)
jo means 'to exceed', and sai means 'to purify mind and body', so Renjosai = "to exceed even the lotus in developing a pure mind and body"
Yone is the character 'bei' meaning rice, and kuni is the Japanese character 'hou' meaning country. In Japanese, America is written as 'rice country' (why they didn't use 'wheat country' is beyond me, but anyway the idea is 'rice' = 'food' = 'prosperity', America is the land of prosperity) So Yonekuni means 'he from America'
Regularly just Kuroda Renjosai is used, and since most folks just call me ren anyway, not much changes. But for official use (on certificates, etc.) the full name is used.
Now if I can convince my company to redo the Japanese on my business cards!

Practice was brutal, as always. Tanaka-sensei came again and after running through all 20 forms, we each worked on our own things, with Tanaka-sensei coming around and giving advice. Of course we all practiced the five forms we need for the upcoming competition end of June. I'm very nervous because I'm in the 4/5dan (highest) division, and besides squaring off against the best, that group includes my own instructor, Kanai-bashocho. I really want to do my best and see how far I can get, but do I beat my own instructor? Niina-gosoke always tell us "get better than your instructors! Your job as student is to excel past them!", but can I really beat her? I mean, first of all she's DAMN good, second of all she has the LaserEyeDeathBeam: one glance from her can freeze a raging bull in its tracks.

After the regular 2 hours, Niina-gosoke schooled us again in his Hour Of Pain. He showed us what the final diagonal cut of the first form shin is supposed to look like: the hands come out and down from overhead straight, just like with a typical straight down cut, but the wrists subtly angle the sword tip out so that the cut catches the opponent not straight in the forehead, but in the base of the neck and cuts down at a 30 degree angle through to under the ribs on the other side. The trick is you can't see that the cut is coming in diagonally. When the cut is down the hands are off to the side; that's the only indication that the cut was diagonal not straight. No telegraphing a diagonal cut by moving the hands to the side as the cut starts, or obviously opening the sword tip to the side to make the cutting angle. How the HELL do I do that?
