Tetsugai

Publishing video is not stable.(My style)
If not publishing video, I may use other SNS.
Part of video also be available on Nicovideo(Japanese only), 
but you should watch on Youtube.

If you use my video to copy, please check the https://twpf.jp/Tetsugai_Leader (It is written only Japanese)

I can understand only Japanese and English. I am Japanese student.
So, I don't reply to the comment which used other languages.Please be careful.
