Language barrier aside, I was able to take away a few things from this video. I admit to making some assumptions, but I think they are solid.
She is a serious about models. She builds kits of all sorts (armor, ships, cars, motorcycles, etc), she paints them, weathers them, etc. I haven't see her use PE (Maybe I just haven't watched enough), but otherwise she does everything I do to my kits.
Without subtitles it is impossible to know for sure, but I suspect this was an out of the box build, which is why some of the fit issues weren't address with a bit of glue. She clearly was capable of fixing them if she wanted to, and because she didn't I think it is an out of the box build.
The Fujimi kit looks interesting. The fit was pretty good, and it looks like a bit of glue would have corrected those pieces that didn't fit great. This type of kit wouldn't be my go-to, but it has lots of appeal after a build with lots of fit issues and fiddly PE. It is something younger kids could easily help/do without worrying about messy stuff like glue and paint. The price seems high, but I have a 1/700 scale destroyer I am building/rebuilding which cost over twice that much once all the after market stuff was purchased. And at the distance most people are going to see it, it looks like a KONGO.
That was well worth the 25 minutes or so I spent watching it at lunch. Thanks for sharing.
