Over Yon-dan, 4th grade are called Sensei, an instructor of Ken-do

I was asked to instruct kids in Do-jo with masters belonging the Do-jo.
They are over Nana-dan, 7th grade of Ken-do.
Yes, they are true masters of Ken-do.

I could not instruct kids in the Do-jo for some reasons,
Firstly I should recall my skill of Ken-do and the way of thinking for Ken-do.
I was 3rd grade, San-dan at 2014, I did not worth instructing other person.
Basically I had no confidence to my skill and know-how to instruct kids.

All kids in Ken-do Do-jo want to take on gears. But they cannot put them on till they can do basic moving and handle their Shinai, sward of bamboo.
