Sword of Mikie?!
The text above the video says it's from the January 1986 issue of MicomBASIC. You're in luck!

Normally you can search the text of a magazine but for this one it's broken. So I found it in the raw text file which seemed to indicate is was on page 112, and then used web viewer to quickly locate the page.
You will need to type in the code yourself. But it's "only" one page split into four columns.
There are lots of "forgotten" games out there (dozens of type-in games in this one issue alone! though not all are for MSX). Some Japanese fans that I follow on Twitter have special software that will take a scan an recognise the code listing directly — removing the need for typing!

Wow! I'm saving those to type it as soon as I get some free time 
Thank you so much for that! 
I THINK I typed the first one

I placed some random text where there was japanese, but other than that I believe this should be right 
Now it will wait for a while, I have a whole (non msx) project to finish this month :/
