Help with a harmonica song

So, yes, I’ve decided to go down the long and treacherous path of learning a song that I heard in an anime -_-. The song in question is this :

I’m only a novice when it comes to the harmonica so I can’t figure it out by ear and googling for a tab has yielded no results. Has anyone found a tab for this or could anyone tab this out?
My humble thanks.
