To answer your first question, there are scenes in the LN that depict the armies charging and I'm sure the anime will show this based on the most recent episode's depiction of the Demi-human's charge towards the human armies.

As far as your second question, I'm a little confused as to what you are asking. I'm not sure what videos or "portal music" you are talking about. if you could give some clarification I might be able to answer your question(s). That aside, I'm sure the anime will not disappoint the epicness of the armies charging into battle.
