I don't see how this would be any less realistic than Stallone single-handedly defeating a whole company of enemies in any of his numerous action movies. That's just how you make a tough hero character.

This seems to be going pretty decently. Production values aren't terrible at all. The English scanlation is obviously fully English, so it's interesting to listen to the dialogue, which has all the Japanese expressions and such, which got lost in the translation. A bit like watching the Japanese Skyrim gameplay, I guess.
