Ninja music

you were new to the ninja dojo, it was located in the forest, well hidden to deny the existence of ninjas but not too far from the city, when you entered the dojo you saw more ninjas hanging out, it was a nice place lined with decorations, you saw a group of 6 ninjas eating rolls but with their masks down only to their mouths, while you were walking down the hall of rooms you ran into a barefoot ninja with headphones, when you both fell to the ground the ninja just got up and bowed in apology, waiting for you to accept and to adjust his headphones
