Sounds like things aren't going so well with the new guy. Did you ever ask him what style of Aikido he did before coming to your dojo? We have someone from Aikikai come to our dojo a year ago, with 12 years under his belt. It took him months to switch over to our way of moving. Younger kyu rank students probably would have a harder time with this- imagine learning 2 years of French and suddenly being switched over to Korean. Also, if he dosen't know how to do a techinique, don't belittle him for it. Beginners are beginners. And yes, beginners (often young, male ones) often crank techinique and then either flop down like a dead fish or never fall at all.
My main concern is why are you so happy about the idea of getting all the sempai to avoid him? Do you think your kohai are magically going to do better with him? As sempai, you should be preventing him from working out with your kohai and working on him. When we get a new belt in our dojo, Sensei says you take on the rank AND responsibility of that rank.
I get it- egotisical people suck. My Sensei has a dojo and a college dojo and I'm in both. And I've watched freshman do the same thing to me and to people who have been practicing longer than I have been alive.
At a year he should be doing better, but just remember- you and everyone in the dojo let this problem go on for that long. And he has been doing this despite being told not to. Don't just blame the kid, blame the parent as well.
Yeah. The funny thing is he has stated he trained at two dojo's both know for "hard"style Aikido. One Aikikai and another Yoshinkan. I watched the sensei from the Aikikai dojo on you tube and this guy does not move at all like the sensei. And the Yoshinkan school is well known for instilling basics into the ground also. I was surprised this guy moved like an AIkibunny. Taking this into account along with him stating several thousand hours of practice ( Shouldn't he be a Sandan or Yondan?!?!?) despite having being a very low kyu and not much to how for basic movement. We aren't trying to belittle him when we practice just trying to get the correct movement so he can do the technique, which he does not like.
I am not happy about the sempai not practicing with him but it does keep the peace in the dojo. He honestly seems not wanting any help or practice with sempai. He just wants to do what he "interprets" as correct and no one should tell him other wise. At least when he practices with mudansha, I think he is not intimidated by them and can just do what he wants. How can we help someone that does not want help? This guy supposedly also refuses to test in previous dojos. He skipped the last test at our dojo until sensei forced him to test. I honestly think there is issues of not taking pressure well and also maybe being a 5th kyu shihan attitude.
You are right about it being partially our fault. I told my Sensei early on when I watched the guy and practiced with him that there was an issue there. Nothing came of it. This guy obviously does not want to learn our style and is too good to relearn the basics. Slowly I started hearing things through the grapevine about his practice issues. No one did anything until I felt something had to be done. Since our "Talk" I haven't see him much although he still comes to class and avoids anyone he has issues with like the plague.
